Florida Death Row Inmate Executed: Triple Family Murder, Sets Bodies on Fire. Last Words: “No apologies”

After 33 years, 4 months, and 29 days on death row, David Joseph Pitman faced his fate in Florida. He was 53 years old when the lethal injection ended his life inside the chamber at Florida State Prison. By then, his name was already etched in the state’s history as the man responsible for one of Polk County’s most brutal family massacres.

At 6:12 this evening, Pitman was pronounced dead, still insisting with his final breath that he was innocent of the crimes that condemned him.

It was May 2nd, 1990, in the quiet Mulberry community of Polk County. The spring air carried no warning of the violence about to unfold. Inside a modest home on the outskirts of town lived Clarence and Barbara Knowles, a middle-aged couple, along with their 20-year-old daughter, Bonnie. They were ordinary people going about the rhythms of family life, unaware that the night would be their last.

The phone lines had been cut. The house, wrapped in shadows, stood vulnerable in the silence. Neighbors slept peacefully, never suspecting that behind the walls of the Knowles residence, terror was breaking loose.

Sometime after midnight, the intruder struck. Clarence, Barbara, and Bonnie were each attacked with savage force. Blades tore through flesh in a frenzy of violence that left no chance of survival. The floors ran slick with blood, the walls echoing with the final cries of a family caught in the crosshairs of vengeance.

But the crime did not end there. As the life drained from the victims, flames soon roared through the rooms. The house, once filled with the warmth of family, became an inferno designed to erase evidence of the carnage inside. And outside, their stolen car was later found burned as well—a final effort to cover tracks. By dawn, three lives were gone, their home reduced to ash, and a community left in horror.

Investigators arriving at the scene were confronted not just with the destruction of a family, but with the beginning of a case that would span decades—one that would eventually lead to the execution chamber, where David Pitman met his end.

But to understand how David Pitman, a young man, became the name tied to one of Florida’s most chilling family murders; how one night of violence destroyed three lives and condemned another to decades on death row; and why his case still raises questions about guilt, mental capacity, and the death penalty, we have to go back. Back to May 2nd, 1990. Back to a modest Mulberry home just off the back roads of Polk County. Back to the night when Clarence, Barbara, and Bonnie Knowles were trapped inside their house of fire and blood and never made it out alive.

David Joseph Pitman entered the world on December 10th, 1961, in circumstances that would shape a lifetime of pain. Born into extreme poverty in Florida, David’s earliest memories were of violence and fear. His mother would mercilessly beat him and his siblings with belts, broom handles, and two-by-fours, starting when David was just four years old. The abuse wasn’t occasional; it was systematic. David’s mother confessed she would whip him with a belt, sometimes every day. When asked about her treatment of her children, she described David as a “child no mother would want.”

The psychological damage ran deeper than physical wounds. She would threaten her children that if they called Child Protective Services, while she might go to jail for a day or two, “when they let me out, you’re going to the hospital.”

David’s father brought additional chaos to the household. Diagnosed with paranoid schizophrenia, he created an atmosphere of unpredictability and mental instability. The combination of an abusive mother and mentally ill father created what one expert would later describe as an almost totally dysfunctional family environment.

At school, David’s problems became more apparent. Teachers noticed his inability to focus and learn at the same pace as other children. He was placed in classes designed for emotionally handicapped and autistic students. His IQ tests consistently showed scores in the low 70s, indicating significant intellectual limitations. Despite these clear signs of developmental issues, David’s family lacked the resources to provide proper help.

The physical abuse left lasting marks beyond bruises. David suffered multiple head injuries during his childhood, including being hit with either a brick or a rock. At age six, he passed out while trying to siphon gasoline from an old car with a hose—an incident that may have caused additional brain damage. These injuries, combined with the ongoing trauma, created a foundation of cognitive and emotional problems that would follow David throughout his life.

When David did receive some professional help, it was brief and inadequate. A psychiatrist prescribed Ritalin for his attention deficit disorder and saw him four or five times. However, the family couldn’t afford to continue the visits or medication. The treatment stopped, leaving David without the support he desperately needed.

According to later reports, David’s sexual abuse began between 8 and 9 years old. He was raped three or four times by one man and sexually assaulted on two other occasions by another individual. This trauma, according to later psychological analysis, contributed to David’s adult behavior patterns of taking extreme risks and projecting an image of toughness that nothing could penetrate. By the time David reached adolescence, the damage was extensive. The boy who entered his teenage years carried wounds that went far beyond what anyone could see on the surface, setting the stage for the troubled adult he would become.

As David moved into young adulthood, his intellectual limitations became more apparent in practical situations. Despite his cognitive challenges, he managed to develop some mechanical skills. He learned to work with tools and eventually built his own tow truck. David’s criminal behavior began during this period, though initially, it was relatively minor. He had encounters with law enforcement that suggested poor impulse control and difficulty understanding consequences. His 1985 conviction for aggravated assault established a pattern of violence that would become relevant in later legal proceedings.

During his late teens and early 20s, David began using alcohol and drugs as a way to cope with his psychological pain. He would drink at least two to four drinks daily, and his substance use increased during periods of stress. This self-medication provided temporary relief from the constant anxiety and depression that resulted from his traumatic childhood, but it also impaired his already limited judgment.

In the mid-1980s, David Pitman met Marie Knowles, a young woman. Their relationship developed against the backdrop of David’s unresolved trauma and continuing psychological problems. Marie came from what appeared to be a more stable family situation, though her own life had its challenges. Marie’s parents, Clarence and Barbara Knowles, lived in Mulberry, Florida, in a modest home at 500 NE 4th Street. Clarence was 60 years old, Barbara was 50, and they had raised their daughters in what neighbors described as a quiet, working-class household. The family included Marie and her younger sister Bonnie, who was 20 years old at the time she would meet David.

When David and Marie married, they quickly started a family. Their first child, Cindy, was born on January 13th, 1986. Robin followed on March 17th, 1987, and their youngest, Wendy, was born on December 27th, 1988. The three children became the center of the family’s life, but David’s psychological problems made him an unpredictable father and husband.

The young family lived in difficult financial circumstances. David’s intellectual limitations and lack of education made steady employment challenging. His drinking problem continued, and he struggled with the responsibilities of marriage and parenthood. Marie increasingly relied on her parents for support, both financial and emotional. The three children spent considerable time with their grandparents and eventually moved in with Clarence and Barbara Knowles full-time.

David’s relationship with the extended Knowles family became strained as his behavior grew more concerning. Family members noticed his quick temper and inappropriate responses to normal family conflicts. His drinking increased during periods of stress, and his decision-making became even more impaired. The intellectual disability that affected his judgment was compounded by alcohol abuse and untreated mental health issues.

The marriage began deteriorating as Marie recognized the extent of David’s problems. His inability to maintain steady employment, combined with his drinking and unpredictable behavior, created constant tension. Marie found herself effectively raising three young children while dealing with a husband whose cognitive and emotional limitations made him more of a burden than a partner.

By 1989, the situation had reached a breaking point. Marie discovered that David’s problems extended beyond intellectual disability and substance abuse. That year, Bonnie Knowles, Marie’s 20-year-old sister, reported to authorities that David had raped her. The incident had allegedly occurred when she was 15, making her a minor at the time of the assault. However, the case was dropped by state prosecutors who determined that too much time had passed since the alleged crime.

This revelation devastated the family relationships and created additional stress for everyone involved. The Knowles family now viewed David not just as a troubled son-in-law, but as a potential predator who had victimized their youngest daughter. Marie was forced to confront the possibility that her husband was capable of sexual violence against a family member who was essentially still a child when the alleged assault occurred.

The failed prosecution of the rape case created lasting resentment and fear within the family. David knew that the allegations had been made, and he understood that the Knowles family viewed him with suspicion and hostility. Clarence and Barbara found themselves in the difficult position of supporting their daughter while protecting their younger daughter and grandchildren from someone they now viewed with deep suspicion. They encouraged Marie to consider ending the marriage while also taking practical steps to ensure the safety of everyone in their household.

Throughout 1989 and into early 1990, the relationship between David Pitman and the Knowles family deteriorated rapidly. What had begun as typical in-law tensions, complaints about money, and David’s inability to hold steady employment, evolved into something far more concerning. As David’s behavior became increasingly erratic and threatening, the family found themselves walking on eggshells around someone they now feared was genuinely dangerous, measuring their words and actions against the possibility of triggering his volatile temper.

The situation became more complicated when Marie served David with divorce papers while he was incarcerated in state prison on charges related to his 1985 conviction for aggravated assault. The original assault had occurred during a period when David’s frustration with his inability to control his circumstances had boiled over into physical violence against someone he perceived as disrespecting him.

The incident had taken place at a local bar where David had been drinking heavily, and according to court records, he had attacked another patron with a broken beer bottle after a verbal disagreement escalated. The 1985 assault case had revealed disturbing details about David’s capacity for sudden, explosive violence when his limited coping mechanisms were overwhelmed. Witnesses testified that David had seemed calm one moment and then erupted into savage violence the next, attacking his victim with a ferocity that shocked even the other bar patrons who were accustomed to occasional fights. The victim had required extensive medical treatment for lacerations to his face and neck—wounds that came dangerously close to causing permanent disfigurement or death.

David had been sentenced on March 12th, 1986, to a split sentence that included 18 months in state prison followed by 3 years of supervised probation. He served his initial prison term and was released in late 1987, beginning what should have been a period of rehabilitation and reintegration into society. However, David’s intellectual limitations and resistance to authority had made him a poor candidate for successful probation completion.

The probation period was designed to provide him with counseling and anger management services while monitoring his behavior to prevent future violent incidents. David was required to attend regular meetings with his probation officer, participate in court-ordered anger management sessions, submit to random drug and alcohol testing, and avoid any criminal activity. He was also prohibited from consuming alcohol and required to maintain steady employment—conditions that proved extremely difficult for someone with his cognitive limitations and psychological problems.

David violated the terms of his probation repeatedly, initially through what seemed like minor infractions such as missed appointments with his probation officer and failed drug tests that revealed continued alcohol and substance abuse. However, these violations revealed his fundamental inability to comply with court orders and his lack of understanding about the consequences of his non-compliance.

The violations escalated over time, moving from administrative failures to more serious behavioral problems that demonstrated his continuing dangerousness. He had threatened his probation officer during a meeting when confronted about missed sessions, telling the officer that he knew where he lived and that people could get hurt if he was pushed too hard. These threats had been documented and reported to the court as evidence of David’s deteriorating compliance with probation terms.

David had also been arrested for disorderly conduct during domestic disputes with Marie—incidents that violated his probation conditions regarding criminal activity and demonstrated that his violent tendencies were now focused on family members rather than strangers. These domestic incidents had become more frequent and more severe, with neighbors calling police multiple times to report shouting, threats, and sounds of violence coming from the Pitman household.

His current incarceration had resulted from the accumulation of these probation violations, which had eventually overwhelmed the court’s patience with his repeated non-compliance. The judge had revoked David’s probation and ordered him to serve the remainder of his original sentence, plus additional time for the violations. This incarceration period was what provided Marie with the opportunity to serve divorce papers while David was unable to physically retaliate.

David’s release from state prison in early 1990 marked the beginning of the final, most dangerous phase of his deteriorating relationship with the Knowles family. He emerged from incarceration bitter, humiliated, and consumed with rage over the divorce proceedings that had progressed without his input or consent. The months of forced separation from his family had not provided him with time for reflection or rehabilitation. Instead, they had allowed his resentment to fester and his plans for revenge to crystallize into specific, actionable threats.

Upon his release, David discovered that his world had fundamentally changed during his absence. Marie had established a life independent of his control. The children were thriving under their grandparents’ care, and the Knowles family had organized their household around his permanent absence. The legal proceedings for the divorce had advanced significantly with temporary custody arrangements, asset division proposals, and restraining order petitions all filed while David was powerless to intervene from his prison cell.

The restraining orders that had been put in place during David’s incarceration legally prohibited him from contacting Marie or going near the Knowles residence. He viewed the restraining orders as further evidence of the conspiracy against him rather than as legitimate legal protections for his estranged family. David’s first weeks of freedom were marked by increasingly desperate attempts to reestablish contact with Marie and regain access to his children.

He began by trying to approach Marie at her workplace, timing his visits to coincide with her lunch breaks and shift changes. When security personnel at her job site intervened and reminded him of the restraining order, David became argumentative and threatening, requiring police intervention on multiple occasions. The confrontations at Marie’s workplace revealed David’s deteriorating mental state and his inability to accept the reality of his situation. Witnesses reported that he seemed genuinely confused about why he wasn’t allowed to speak with his wife, alternating between pleading for reconciliation and making veiled threats about what would happen if she continued to refuse his attempts at contact.

His speech was often rambling and repetitive, circling back to the same grievances and justifications while becoming increasingly agitated when people failed to agree with his perspective. David’s behavior during these workplace incidents demonstrated the dangerous combination of his intellectual disability and his escalating paranoia. He couldn’t understand why Marie’s co-workers and supervisors viewed him as threatening, interpreting their fear and hostility as further evidence that they had been turned against him by the Knowles family. In David’s distorted thinking, everyone who supported Marie’s right to divorce him was part of an elaborate conspiracy designed to destroy his life and steal his children.

When direct approaches to Marie proved impossible due to legal restrictions and workplace security, David began focusing his attention on the Knowles family home where his children were living. He knew that the restraining order prohibited him from approaching the residence, but his desperation to see his children and his anger toward the grandparents who were harboring them overwhelmed his limited impulse control.

David began conducting surveillance of the Knowles house, parking his distinctive homemade wrecker truck in locations where he could observe the family’s daily routines without being on their property. He would sit in his vehicle for hours watching as Clarence and Barbara took the children to school, went grocery shopping, or played in the yard. These surveillance sessions fed his obsession while providing him with detailed information about the family’s schedules and security arrangements.

The surveillance behavior represented a significant escalation in David’s stalking pattern, moving from random drive-bys to systematic observation and intelligence gathering. Neighbors began reporting the presence of David’s truck in their neighborhood, expressing concern about his obvious monitoring of the Knowles family. The truck itself had become a symbol of menace in the community as residents learned to associate its presence with potential violence and instability.

During these surveillance sessions, David’s resentment toward Clarence and Barbara intensified as he watched them providing his children with the stability and care that he felt should be his responsibility. In his distorted thinking, the grandparents had stolen not just his wife but his role as a father, replacing him in his children’s affections and daily lives. He observed their interactions with growing rage, interpreting every moment of happiness and security he witnessed as further evidence of the injustice being done to him.

David’s obsession with his lost family began consuming every aspect of his daily life. He had difficulty maintaining the employment that was required as a condition of his release, as he spent more time conducting surveillance and planning confrontations than focusing on work responsibilities. His few friends and family members reported that he talked about nothing except the divorce proceedings and his plans for dealing with the Knowles family.

The federal investigation into equipment theft charges that had been proceeding during David’s incarceration was now reaching a critical phase, with federal agents preparing to file formal charges that could result in decades of additional prison time. David’s obsession with his family situation made it impossible for him to focus on his legal defense or take the steps necessary to minimize the consequences of the federal charges. His attorney reported difficulty communicating with David about his defense strategy as every conversation devolved into rambling complaints about his family situation.

As winter turned to spring in 1990, David’s behavior became increasingly erratic and threatening. The Knowles family’s fear had evolved from general concern about David’s threats to specific terror about what he might do during one of his surveillance missions. They had installed additional security measures and maintained constant vigilance. But they understood that their safety ultimately depended on David’s choices—choices that his deteriorating mental state made increasingly likely to result in violence.

By May 10th, 1990, David’s psychological state had deteriorated to a point where those who encountered him described a man barely recognizable as the person they had known. His father, Eugene Pitman, would later testify that David seemed different during his visits, displaying an agitation and fixation that went beyond his usual problems. David’s conversations had become entirely consumed with elaborate plans for confronting the Knowles family and reclaiming what he viewed as his stolen life.

The upcoming court date for his divorce proceedings, scheduled for late May, had created a sense of urgency that pushed David closer to the edge of action. He understood that the legal system was moving toward a permanent resolution that would formalize his loss of Marie and the children. The finality of this prospect became an obsessive fear that drove increasingly desperate thinking about how to prevent what seemed inevitable.

On May 12th, David made what would be his final attempt to resolve the situation through legal means, appearing unannounced at his divorce attorney’s office in an agitated state. The attorney, who had been struggling to maintain professional representation of someone whose behavior had become increasingly erratic, reported that David was confused about basic legal concepts and seemed unable to understand that his threats against his estranged family were actually harming his case rather than helping it.

During this meeting, David demanded that his attorney find a way to stop the divorce proceedings and force Marie to return to him with the children. When the attorney explained that such actions were legally impossible and that David’s threatening behavior had actually strengthened Marie’s case for permanent separation, David became enraged and accused the attorney of being part of the conspiracy against him. The attorney’s notes from this final meeting described David as beyond rational legal consultation and exhibiting signs of what appeared to be paranoid thinking that made effective representation impossible.

David’s inability to comprehend basic legal concepts, combined with his escalating threats and delusional expectations, led the attorney to file a motion to withdraw from the case. David’s reaction to his attorney’s withdrawal was to interpret it as further evidence that everyone was working against him, including the legal professionals who were supposed to be helping him. This perceived betrayal eliminated what had been his last connection to legitimate resolution of his problems, leaving him with only violence as a means of achieving what he wanted.

The loss of legal representation coincided with news that the federal equipment theft charges were likely to be filed within days, creating additional pressure on David’s already fragmented thinking. The federal investigation centered on a sophisticated operation where David had allegedly been stealing heavy construction equipment from job sites across central Florida and selling the machinery through his towing business to unsuspecting buyers who failed to verify the equipment’s legitimate ownership.

The scope of the federal case was extensive, involving multiple counts of interstate transportation of stolen property, conspiracy to commit theft, and racketeering charges that federal prosecutors had been building for over 18 months. David’s distinctive homemade wrecker truck had been identified at numerous construction sites where expensive equipment had subsequently disappeared, creating a pattern that federal investigators had methodically documented through surveillance footage, witness interviews, and forensic analysis of tire tracks and other physical evidence.

The stolen equipment included bulldozers, excavators, generators, and other heavy machinery worth hundreds of thousands of dollars that David had allegedly transported using his wrecker to remote locations where the identifying numbers could be altered or removed before sale. Federal agents had traced some of the stolen equipment to buyers in neighboring states, establishing the interstate commerce elements necessary for federal jurisdiction and significantly increasing the potential penalties David faced.

The investigation had revealed what prosecutors characterized as a criminal enterprise that had been operating for several years, with David allegedly working with associates who helped identify valuable equipment at construction sites and provided information about security measures and work schedules that would facilitate theft. The conspiracy charges alone carried potential sentences of up to 20 years in federal prison, while the racketeering counts could add additional decades to any sentence.

Federal agents had executed search warrants at David’s business location and residence, seizing records that documented his financial transactions and revealed patterns of income that appeared inconsistent with his legitimate towing operations. Bank records showed large cash deposits that occurred shortly after reported equipment thefts, creating circumstantial evidence that supported the prosecution’s theory about his criminal enterprise.

The asset forfeiture component of the federal case had frozen David’s bank accounts and placed liens on his property, including his towing equipment and the homemade wrecker that was central to both his legitimate business and his alleged criminal activities. This financial pressure had made it impossible for him to retain private legal counsel for either his federal case or his divorce proceedings, adding economic stress to his existing psychological problems.

David understood that once the federal charges were filed, he would probably be arrested and returned to prison for a period that could last decades, potentially extending well into his 60s or 70s if he were convicted on multiple counts. The federal sentencing guidelines for his alleged crimes, combined with his existing criminal record, virtually guaranteed that any federal conviction would result in a lengthy prison term that would effectively end his chances of rebuilding relationships with his children or having any meaningful life after incarceration.

The timing of the federal charges was particularly devastating because they threatened to finalize his separation from his family just as the divorce proceedings were reaching their conclusion. David’s limited intellectual capacity made it difficult for him to understand the complex legal processes involved in both cases, but he clearly grasped that the combined effect of the criminal charges and divorce would permanently remove him from his children’s lives during their formative years. The prospect of losing the remainder of his life to federal imprisonment while his family moved on without him became the final trigger for his decision to act violently.

In his distorted thinking, the federal charges represented the ultimate injustice—punishment for crimes he believed others committed with impunity while he was being singled out for persecution by law enforcement agencies that were working in conspiracy with his estranged family to destroy his life completely. David’s paranoid interpretation of the federal investigation prevented him from recognizing that his own criminal behavior had created the legal consequences he faced. Instead, he viewed the charges as further evidence that everyone was working against him, reinforcing his belief that violent action against the Knowles family was justified as a response to the systematic destruction of his life that he believed they had orchestrated.

The psychological pressure created by the imminent federal charges pushed David beyond his already limited capacity for rational decision-making and into the realm of desperate violence that would ultimately cost four people their lives and seal his own fate as a condemned man.

David spent May 13th and 14th in intensive preparation for what he decided would be his final confrontation with the Knowles family. He gathered supplies that would be needed for his plan, including gasoline for destroying evidence and tools for gaining entry to the house if necessary. His preparation was methodical and thorough, demonstrating that despite his intellectual limitations, he was capable of complex planning when motivated by overwhelming rage and desperation.

During this final preparation period, David’s behavior became noticeably different, even to casual observers. Neighbors reported seeing him driving slowly through their area multiple times per day, sometimes stopping to stare at the Knowles house for extended periods before moving on. His presence had become so routine that some neighbors had begun timing their own activities to avoid encounters with him.

The intensity of David’s surveillance during these final days created considerable fear within the Knowles household as family members could sense that his behavior had shifted from general threats to active preparation for violence. Clarence and Barbara discussed whether they should leave their home temporarily, but the presence of the children and their limited financial resources made evacuation seem impractical and potentially unnecessary if David was simply engaging in intimidation rather than actual planning.

On the evening of May 14th, David made his final visit to his father’s house, ostensibly to spend time with his stepsister, Bobby Joe, but actually to establish the alibi that he believed would protect him from suspicion after the murders. His conversation with family members that evening was described as strangely calm and focused, lacking the agitation and rambling complaints that had characterized his recent interactions.

As the evening of May 14th progressed toward the early morning hours of May 15th, David waited for the opportunity to implement the plan he had spent weeks developing.

As the clock moved past 2:00 a.m. on May 15th, 1990, David Pitman made his final preparations at his father’s house on the outskirts of Mulberry. Bobby Joe Pitman, his stepsister, who had provided him with companionship throughout the evening, prepared to leave at her usual time of 2:30 a.m. Her departure would remove the last witness to David’s whereabouts and provide him with the window of opportunity he had been waiting for.

The timing of Bobby Joe’s departure was not coincidental. David had carefully observed her routine during previous visits and knew that she consistently left at 2:30 a.m. to return to her own home. This predictable schedule had become part of his plan, as it would give him approximately 40 minutes to carry out his intended actions before anyone might expect him to be accounted for again.

After Bobby Joe’s car disappeared into the darkness, David gathered the supplies he had prepared for this moment. The gasoline he had acquired was loaded into containers that could be easily transported, and he had ensured that he possessed the tools necessary for gaining entry to the Knowles residence if the doors were locked. His preparation demonstrated a level of methodical planning that contradicted any suggestion that what was about to occur would be impulsive or unpremeditated.

The half-mile walk from his father’s house to the Knowles residence on NE 4th Street took David approximately 13 minutes. David’s approach to the Knowles house revealed the extent of his advanced planning and his detailed knowledge of the property’s layout. Rather than approaching the front door directly, he moved to the exterior of the house where the telephone line entered the building. Using a sharp instrument he had brought for this purpose, David severed the phone line, ensuring that none of the family members would be able to call for help once his attack began.

With the phone line disabled, David approached the front door of the house where his estranged wife’s family lay sleeping. The house was quiet and dark, with no indication that anyone inside was aware of the danger that had just arrived on their doorstep. Inside, Clarence and Barbara Knowles were sleeping in their bedroom, while 20-year-old Bonnie was in her own room.

According to the prosecution’s reconstruction based on jailhouse informant testimony, David knocked on the front door with sufficient force to wake the occupants, but without creating the kind of disturbance that would alert neighbors. Bonnie Knowles responded to the knocking. David identified himself and requested entry, likely claiming that he needed to discuss the family situation or see his children.

The decision by Bonnie Knowles to open the door to David represented a tragic miscalculation about his intentions and mental state. Bonnie’s decision to admit David into the house reflected the complex dynamics that often exist in domestic violence situations where victims feel compelled to manage their abuser’s behavior through accommodation rather than confrontation. Her choice may also have been influenced by concern for the sleeping children and a desire to prevent David from creating a disturbance that would wake and frighten them.

Once inside the house, David moved immediately toward Bonnie’s bedroom, where she had allowed him entry. David’s interaction with Bonnie quickly turned violent when she refused his sexual advances. He attacked her with a hunting knife, stabbing her multiple times before cutting her throat to silence her screams for help.

The sounds of the violent assault on Bonnie awakened Barbara Knowles, who came from her bedroom to investigate what was happening to her daughter. David encountered Barbara in the hallway outside Bonnie’s room and immediately attacked her to prevent her from escaping or calling for help. He stabbed Barbara three times with wounds to her neck and chest that caused rapid fatal bleeding within approximately 5 minutes.

The commotion in the house woke Clarence Knowles, who attempted to reach the telephone in the living room to call for assistance. David intercepted him before he could complete the call, attacking him with the same knife he had used to kill the two women. Clarence was stabbed multiple times with wounds that caused him to collapse and die in the living room area of the house.

Bonnie had suffered eight stab wounds, five of which were potentially fatal, along with the deep cut across her throat. Barbara’s three stab wounds included one to the neck and two to the chest, with the chest wounds proving immediately fatal. Clarence’s multiple stab wounds had caused massive blood loss that resulted in his death within minutes of the attack.

The entire sequence of murders took place within a span of approximately 10 to 15 minutes. According to the prosecution’s timeline, each victim was killed in a different location within the house: Bonnie in her bedroom, Barbara in the hallway between bedrooms, and Clarence in the living room area, indicating that David had pursued family members as they tried to flee or seek help after being awakened by the initial attack.

After completing the murders, David’s actions demonstrated the same methodical planning that had characterized his approach to the house. He poured gasoline throughout the residence, creating the conditions for a fire that would destroy physical evidence of his presence and potentially mask the true cause of the victims’ deaths. The accelerant was distributed in multiple rooms, indicating that David had moved systematically through the house to ensure maximum destruction.

The timing constraints that David faced—needing to complete the murders, set the fire, steal Bonnie’s car, drive it to a disposal location, abandon it, return on foot to burn the vehicle, and flee the scene, all within his 40-minute window—required efficient execution of a complex plan.

At approximately 3:10 a.m., as David was implementing the final phases of his plan, newspaper delivery man David Hess observed a burst of flame on the horizon that marked the moment when the Knowles house became fully engulfed in fire. Hess contacted the Polk County Sheriff’s Office to report the fire, providing the first official documentation of the tragedy that had just unfolded on NE 4th Street in Mulberry.

While emergency responders were being dispatched to the scene of the house fire, David was executing the next phase of his plan with the same methodical precision that had characterized his approach to the murders. He had taken Bonnie’s car keys during the attack, and her brown Toyota now served as his means of escape from the immediate area. The vehicle represented both transportation and evidence that needed to be destroyed, requiring David to balance his need for mobility with his understanding that the car could link him to the crime scene.

David drove Bonnie’s Toyota approximately half a mile from the burning house to a construction site on a dirt road off Highway 60, a location he had likely selected during his surveillance activities as suitable for his purposes. The construction site was isolated enough to avoid immediate discovery, but accessible enough that he could return on foot to complete his plan for destroying the vehicle. His choice of this location demonstrated the same advanced planning that had characterized every aspect of his actions that night.

At the construction site, David abandoned the Toyota in a ditch beside the road, positioning it in a way that would facilitate the fire he intended to set. The location was far enough from the house to avoid immediate connection by investigators, but close enough that David could return on foot within his self-imposed timeline. The vehicle’s placement also suggested that David understood how fire would spread through the car and wanted to ensure maximum destruction of any evidence it might contain.

At 3:32 a.m., the Polk County Fire Department received the official dispatch to respond to the house fire that David Hess had reported. The 18-minute delay between Hess’s observation of the flames and the official dispatch reflected the normal processing time for emergency calls, but it also provided David with additional time to implement his plan without interference from authorities who were focused on the more obvious emergency at the burning house.

The fire department personnel arrived at the Knowles residence at 3:46 a.m. to find a structure that was already fully engulfed in flames that extended beyond the building itself into the surrounding yard area. The intensity of the fire and its rapid spread indicated the presence of accelerants, though the firefighters’ immediate priority was containing the blaze and determining whether anyone might still be trapped inside.

Within minutes of the firefighters’ arrival, a significant explosion occurred that brought down part of the living room roof, creating additional hazards for the emergency personnel and further intensifying the blaze. The explosion was likely caused by accelerant vapors that had accumulated within the enclosed spaces of the house, creating conditions for rapid combustion when exposed to the advancing flames.

While firefighters battled the blaze at the Knowles residence, David was completing the final phases of his evidence destruction plan. He had returned on foot to the construction site where he had abandoned Bonnie’s Toyota, carrying additional accelerant to ensure the vehicle’s complete destruction. The burning of Bonnie’s Toyota was intended to eliminate any physical evidence that might link David to the crime scene, including fingerprints, blood evidence, or other trace materials that could have been transferred during the murders or his escape from the house.

At 6:30 a.m., construction worker James Trope arrived at his job site and immediately noticed the brown Toyota positioned in the ditch with an orange glow emanating from the back of the vehicle. The car had been recently set on fire, with flames still visible and smoke rising from the burning interior. Trope’s discovery of the burning vehicle provided investigators with their first direct link between the house fire and criminal activity occurring at a separate location.

Trope’s testimony would prove crucial to the prosecution’s case as he not only discovered the burning vehicle but also observed what he described as a homemade wrecker truck near the scene. More importantly, Trope witnessed a man running away from the burning car, providing the first eyewitness account of someone fleeing from a crime scene related to the Knowles family murders. The construction worker’s description of the fleeing suspect was limited due to distance and lighting conditions, but his identification of the homemade wrecker truck provided investigators with a specific lead to pursue.

The truck’s distinctive appearance and David’s known ownership of such a vehicle would eventually create a direct connection between him and the evidence destruction at the construction site. The timing of Trope’s arrival at 6:30 a.m. placed David at the construction site approximately 3 hours and 20 minutes after the initial house fire had been observed, providing investigators with a timeline that would later be used to reconstruct David’s movements and test the feasibility of the prosecution’s theory about how the crimes had been committed.

As dawn broke on May 15th, 1990, the true scope of the tragedy was beginning to emerge. Firefighters had controlled the blaze at the Knowles residence and were beginning the careful process of searching for victims within the burned structure. At the same time, law enforcement was responding to the report of the burned vehicle at the construction site, beginning to piece together evidence that would eventually reveal the connection between these seemingly separate incidents.

As firefighters completed their suppression efforts and the structure cooled sufficiently to allow entry, the systematic search for victims began under the direction of fire marshal investigators who had recognized the suspicious nature of the blaze. Deputy Fire Marshal Steve Knowles, whose shared surname with the victims was purely coincidental but would later create additional emotional weight for his testimony, led the careful examination of the burned structure.

The first body discovered was that of Clarence Knowles, found in the hallway between the kitchen and a bedroom in a position that suggested he had been attempting to move through the house when he was attacked. The location of his body, combined with the medical examiner’s later findings about his injuries, would support the prosecution’s theory that Clarence had been killed while trying to reach a telephone or escape the house after being awakened by the sounds of violence.

Barbara Knowles was discovered in the hallway between two bedrooms, positioned in a way that indicated she had been moving toward the sounds of disturbance when she encountered David and was killed. Bonnie Knowles was found in the bedroom on the northwest side of the house in what had been her private space within the family home. The location of her body and the extensive nature of her injuries supported the prosecution’s later argument that she had been David’s primary target and that the other family members had been killed to eliminate witnesses to her murder.

The absence of the three young children from the burned residence initially created hope among investigators that they might have escaped or been removed to safety before the fire began. However, the subsequent investigation revealed that the children had not been present in the house during the attack, having been staying elsewhere that night—a fortunate circumstance that spared them from witnessing or becoming victims of the violence that claimed their grandparents and aunt.

While investigators processed the scene at the Knowles residence, reports were coming in about the burned vehicle at the construction site that James Trope had discovered. The connection between the house fire and the car burning was not immediately apparent, but the proximity of the two incidents and their timing suggested they were related elements of the same criminal enterprise.

As news of the triple murder began to spread through the small community of Mulberry, investigators started receiving calls from residents who had observed suspicious activity in the neighborhood during the relevant time period. Several callers reported seeing unfamiliar vehicles in the area around the Knowles house, while others mentioned observing someone walking through the neighborhood during the early morning hours when most residents were asleep.

The community’s response to the murders reflected both the shock of violent crime occurring in their quiet neighborhood and the genuine affection that residents had felt for the Knowles family. Clarence and Barbara had been well-regarded members of the community, and Bonnie had been popular among her peers, making their violent deaths particularly devastating for those who had known them.

Marie Pitman’s notification about her family’s murder created immediate complications for the investigation, as detectives had to balance their need to interview her as a potential source of information with sensitivity to her grief and trauma. Marie’s estrangement from David and her ongoing divorce proceedings made her a crucial witness regarding his threats and behavior, but her emotional state made extended questioning difficult during the initial phases of the investigation.

The investigation into David’s whereabouts during the crucial time frame began with interviews of his known associates and family members, including his father Eugene and stepsister Bobby Joe. These interviews were conducted carefully to avoid alerting David to the fact that he was under investigation while gathering information about his movements and behavior during the relevant time period.

Bobby Joe Pitman’s account of spending the evening with David at their father’s house provided investigators with important timeline information, but it also raised questions about David’s activities after her departure at 2:30 a.m. Her description of David’s demeanor that evening would later be analyzed for signs of the psychological preparation that often precedes planned violence.

Eugene Pitman’s interview revealed details about David’s recent visits and his increasingly obsessive conversations about his divorce and the Knowles family. The elder Pitman’s observations about his son’s deteriorating mental state provided investigators with background information about David’s motivation while also establishing patterns of threatening behavior that supported the emerging theory about his involvement in the murders.

By the afternoon of May 15th, less than 12 hours after the murders had been committed, Detective Day and his team had developed enough information to identify David Pitman as their primary suspect. The combination of his known threats against the family, his opportunity during the time frame established by witnesses, and the physical evidence linking him to the scene created a compelling case for his involvement in the triple homicide.

The decision to arrest David was complicated by the need to gather sufficient evidence to support the charges while preventing him from fleeing the area or destroying additional evidence. Investigators had to balance their desire to take him into custody quickly with the requirement to build a case that would withstand legal challenge and result in conviction.

On May 16th, 1990, less than 36 hours after committing the murders that would ultimately cost him his life, David Joseph Pitman would be taken into custody and formally charged with the triple homicide that had shocked the community and set in motion the legal proceedings that would culminate in his execution.

David’s reaction to his arrest was described by the arresting officers as surprisingly passive, lacking the resistance they had expected based on his violent history and the severity of the charges he was facing. His calm demeanor during the arrest process was later interpreted in different ways by prosecution and defense attorneys. The prosecution saw it as evidence of his premeditation and psychological preparation for the consequences of his actions, while the defense would argue that it demonstrated his confusion and intellectual limitations.

During the arrest, officers observed David’s physical appearance and demeanor for signs of recent involvement in violent crime. They noted scratches on his hands and arms that could have been consistent with physical struggle. Though David’s work as a mechanic and tow truck operator could also explain such injuries, his clothing was collected as evidence for forensic examination, particularly for traces of accelerant that might link him to the arson at both crime scenes.

The Miranda warning was read to David with particular care given his documented intellectual disabilities and the serious nature of the charges he would face. Detective Day wanted to ensure that any statements David made during questioning would be admissible at trial, requiring clear documentation that he understood his rights and waived them voluntarily. David’s intellectual limitations made this process more complex as investigators had to balance their need for information with legal requirements for protecting his constitutional rights.

While David was being processed and questioned, investigators continued gathering evidence to support the charges against him. The forensic examination of his clothing revealed traces of gasoline consistent with the accelerant used at both crime scenes, providing physical evidence that linked him directly to the arson. Additional evidence included soil samples from his shoes that matched the dirt at the construction site where Bonnie’s car had been burned.

The search warrant executed at David’s residence and vehicles uncovered additional evidence supporting the prosecution’s case. Investigators found maps of the area around the Knowles house with markings that suggested surveillance activity along with materials that could have been used in the commission of the crimes. His homemade wrecker truck, which had been observed at the construction site, was impounded for detailed forensic examination.

The community’s reaction to David’s arrest was mixed, reflecting both relief that someone had been taken into custody and shock at the identity of the suspect. Many residents had known David through his towing business and his family connections in the area, making it difficult for them to reconcile their image of him as a troubled but harmless individual with the brutal murders he was accused of committing.

Marie Pitman’s response to her estranged husband’s arrest was complicated by her simultaneous grief over her family’s murder and her relief that the person she had feared for so long was finally in custody. Her cooperation with investigators became crucial to building the case against David as she possessed intimate knowledge of his threats, behavior patterns, and psychological state during the period leading up to the murders.

The children, David’s own daughters, who had been spared from the violence by their absence from the house that night, became central figures in the case’s emotional impact. Their loss of their grandparents and aunt, combined with their father’s arrest for the murders, created a tragic situation that would affect them for the rest of their lives. The custody arrangements that had been contentious during the divorce proceedings now became critical decisions about their future care and protection.

On May 17th, 1990, David made his first court appearance for a bond hearing where the full scope of the charges against him was formally presented. The prosecution argued that the premeditated nature of the murders combined with David’s history of violence and threats made him an extreme flight risk who should be held without bond. The brutality of the crimes and the strength of the evidence against him supported their argument for continued detention.

David’s court-appointed attorney faced the difficult task of representing someone whose intellectual limitations made effective communication challenging while also dealing with overwhelming evidence of guilt. The attorney’s initial strategy focused on ensuring that David’s constitutional rights were protected during the legal proceedings while beginning the long process of investigating potential mitigating factors that might influence sentencing if convictions seemed inevitable.

The bond hearing revealed additional details about the prosecution’s case that had not been previously disclosed, including witness testimony about David’s presence at the construction site and the physical evidence linking him to both crime scenes. The strength of this evidence convinced the judge to deny bond, ensuring that David would remain in custody throughout the lengthy legal proceedings that lay ahead.

As David was returned to the Polk County Jail following his bond hearing, he began the transition from suspect to defendant in what would become one of Florida’s most complex death penalty cases. The jail’s housing arrangements placed David in proximity to other inmates who were facing serious charges and looking for opportunities to improve their own legal situations through cooperation with authorities.

Among these inmates was Carl Hughes, a 33-year-old federal prisoner who was confronting the possibility of spending the rest of his life in prison for HUD fraud charges that could result in an 85-year sentence. Hughes had entered a plea of guilty to his federal charges on April 25th, 1990, just 3 days before the Knowles family murders occurred. His sentencing was still pending, creating enormous incentive for him to find ways to demonstrate cooperation with law enforcement that might result in a more lenient sentence.

Throughout his incarceration, Hughes had made multiple offers to testify against other defendants in exchange for consideration from prosecutors. David’s limitations made him particularly vulnerable to manipulation by more sophisticated inmates like Hughes, who recognized that David’s need to talk about his grievances could be exploited for personal advantage. Hughes began encouraging David’s rambling monologues about the Knowles family, carefully listening for details that might prove valuable to prosecutors while appearing to be a sympathetic listener to David’s complaints.

According to Hughes’s later testimony, David began providing detailed accounts of the murders without any prompting or questioning from his cellmate. Hughes claimed that David spoke about the killings as if they were justified responses to the family’s treatment of him, showing no remorse for the violence he had inflicted on three innocent people. The alleged confessions included specifics about how David had gained entry to the house, the sequence in which he had killed the family members, and his methods for destroying evidence.

Hughes reported that David described cutting the telephone lines before approaching the house, ensuring that his victims would be unable to call for help once his attack began. This detail was particularly significant because it had not been released to the public, suggesting that David possessed knowledge that only the actual perpetrator would have. Hughes also claimed that David had provided details about the layout of the house and the locations where each victim had been killed.

The alleged confession included David’s description of Bonnie Knowles letting him into the house when he knocked on the door and his subsequent attack on her when she refused his sexual advances. Hughes testified that David had described stabbing Bonnie multiple times and cutting her throat to stop her screams, then killing Barbara Knowles when she came to investigate the commotion, and finally murdering Clarence Knowles as he attempted to use the telephone.

David Pounds, another inmate housed in the same area of the jail, provided corroborating testimony about David’s alleged admissions. Pounds was facing his own serious criminal charges and dealing with significant mental health issues, including major depression with psychotic features that required psychiatric treatment during his incarceration. Medical records from June 1990 documented his fragile psychological condition and his need for medication to manage his symptoms.

Pounds’s account of David’s confessions was similar to Hughes’s testimony, though he claimed to have heard the details during a different time period. The timing discrepancies in the cellmates’ accounts would later create questions about the reliability of their testimony, but prosecutors viewed the similarities in their stories as corroboration rather than evidence of coordination between the witnesses. Both inmates reported that David had shown no remorse for the murders, instead expressing satisfaction that he had dealt with the family members who had caused him so many problems. They claimed that David had described the killings in graphic detail, including his use of accelerants to destroy the house and his systematic approach to eliminating all potential witnesses to his crimes.

As summer progressed into fall 1990, David’s case moved through the preliminary stages of the legal process while prosecutors built their evidence and prepared for trial. As David Pitman’s 1991 trial approached, both sides faced significant challenges. Prosecutor Hardy Pickard’s case relied heavily on jailhouse informants Carl Hughes and David Pounds, whose credibility was questionable due to their self-serving motivations for cooperation. The physical evidence included gasoline traces on David’s clothing and witness James Trope’s identification of David’s truck at the car burning site, but these had alternative explanations and reliability issues, respectively.

Defense attorneys Robert Norgard and Robert Trogolo faced the formidable challenge of creating reasonable doubt against detailed jailhouse informant testimony and physical evidence linking David to the crime scenes. Their primary strategy focused on attacking the credibility of key prosecution witnesses Carl Hughes and David Pounds by emphasizing their powerful incentives to fabricate testimony in exchange for reduced sentences.

The defense made the risky decision to have David testify on his own behalf, during which he claimed he was sleeping at his father’s house during the murders and denied making any confessions to cellmates. However, this strategy backfired when David’s father, Eugene, testified for the prosecution, directly contradicting his son’s alibi and severely damaging David’s credibility while supporting the prosecution’s timeline.

The defense attempted to present alternative theories, particularly suggesting that Marie Pitman and her new partner might have committed the murders due to custody disputes and her alleged methamphetamine use. They presented witnesses who testified about Marie’s drug use and claimed she had received money from life insurance policies after her parents’ deaths, but could not establish her physical presence at the crime scene or demonstrate her capability to commit multiple murders and arson.

The most significant setback came when the court excluded evidence about alternative suspects Jesse Watson and Aaron Gibbons, despite defense discoveries that these crack cocaine users lived near the Knowles residence and that Gibbons allegedly knew and had dated Bonnie Knowles. Without this potentially powerful alternative suspect theory, the defense lost a crucial avenue for creating reasonable doubt.

The defense extensively presented mitigation evidence about David’s intellectual limitations, childhood trauma, low IQ scores, special education placement, and history of severe physical and sexual abuse. Family members testified about the dysfunctional home environment.

After hearing all the evidence and testimony, the jury began their deliberations to determine David Pitman’s guilt or innocence on the charges of murdering Clarence, Barbara, and Bonnie Knowles. The case had presented them with competing narratives about what had happened on the night of May 15th, 1990, and conflicting evidence about David’s involvement in the crimes.

The jury’s verdict came swiftly and definitively. On April 19th, 1991, exactly one year after the murders, they found David Joseph Pitman guilty on three counts of first-degree murder. They also convicted him of two counts of arson and one count of grand theft auto. The jury acquitted him of the burglary charge, but the multiple murder convictions meant that David was now facing the possibility of the death penalty.

Under Florida law, the same jury that had convicted David would now hear additional evidence during the penalty phase to determine whether he should be sentenced to death or life in prison. The second phase of the trial focused on aggravating and mitigating circumstances that would influence the ultimate punishment.

The prosecution presented evidence of aggravating circumstances that supported a death sentence. They established that David had a prior conviction for a violent felony, the 1985 aggravated assault conviction. They argued that each murder constituted a previous capital felony in relation to the other murders since all three victims were killed during the same criminal episode. Most significantly, the prosecution argued that the murders were especially heinous, atrocious, or cruel. The evidence showed that each victim had suffered multiple stab wounds and that Bonnie Knowles’s throat had been cut. The prosecution emphasized that Bonnie had experienced conscious pain and suffering before her death, making her murder particularly cruel.

The defense team mounted an extensive mitigation case designed to save David’s life by presenting evidence that explained his actions and demonstrated factors that warranted mercy. They called seven family members to testify about David’s background and the circumstances that had shaped his life. The family testimony revealed the full extent of David’s traumatic childhood. His mother, Francis Marie Pitman, took the stand and admitted to the severe physical abuse she had inflicted on David and his siblings. She testified that she had disciplined him severely and acknowledged that he was a difficult child to deal with.

Multiple family members testified about David’s educational difficulties and his placement in classes for emotionally handicapped and autistic students. They described his struggles with basic learning tasks and his need for repeated explanations of simple concepts. This testimony supported the defense argument that David suffered from significant intellectual limitations.

Dr. Henry Dee provided comprehensive expert testimony about David’s psychological condition. He explained that David’s father was a paranoid schizophrenic and that David himself suffered from severe attention deficit disorder with hyperactivity and organic personality syndrome. Dr. Dee described how childhood physical and sexual abuse had combined with organic brain damage to create severe psychiatric disability. The expert testimony painted a picture of a deeply damaged individual whose capacity for normal judgment and impulse control had been severely compromised.

Dr. Dee testified that David had experienced a childhood replete with abuse, both physical and sexual, and that his family and school system had failed to provide appropriate interventions. Dr. Dee also testified that David was not beyond redemption, expressing his belief that David’s psychological problems could be managed through proper medication and counseling. This testimony was intended to demonstrate that life imprisonment would serve society’s interests while preserving the possibility of rehabilitation.

The defense presented evidence of David’s drug and alcohol abuse as additional mitigation, though they acknowledged that substance abuse could be viewed as both mitigating and aggravating, depending on the jury’s perspective. They argued that David’s substance use represented an attempt to self-medicate severe psychological pain rather than simply recreational drug use.

Despite the extensive mitigation case, the prosecution argued that the aggravating circumstances substantially outweighed any mitigating factors. They emphasized the brutal nature of the crimes, the vulnerability of the victims, and the deliberate planning evidenced by the cut phone lines and use of accelerants.

On April 25th, 1991, the jury returned their sentencing recommendation. By a vote of 9 to 3, they recommended that David Pitman be sentenced to death for each of the three murders. Following Judge Tim J. Strickland’s formal sentencing on April 25th, 1991, at age 29, he was transported to Florida State Prison’s death row, joining approximately 300 other condemned inmates.

David’s mandatory direct appeal to the Florida Supreme Court began on September 16th, 1991, challenging various trial aspects, including the admission of prejudicial evidence about his prior crimes, unreliable identification testimony, and the exclusion of alternative suspect evidence. His attorneys argued that jailhouse informant testimony was insufficient to support conviction and that the trial court improperly applied the “heinous, atrocious, or cruel” aggravating circumstance while failing to properly weigh mitigation evidence. After 3 years of consideration, the Florida Supreme Court affirmed David’s convictions and death sentences on September 29th, 1994, rejecting all defense arguments.

On the morning of September 17th, 2025, David Joseph Pitman woke at 5:45 a.m. in his death row cell at Florida State Prison, knowing it would be his last day alive. At 63 years old, he had spent 34 years and 4 months on death row—more than half his life—waiting for this moment while his attorneys pursued every possible legal avenue to save him.

The Department of Corrections followed established protocol for execution days. Throughout the day, protesters began gathering outside Florida State Prison. Approximately 45 people from Our Lady of Lourdes Church in Daytona Beach made the 2-hour journey to witness the execution and voice their opposition to capital punishment. Led by Father Philo, they brought speakers, tents, signs, bug spray, and lawn chairs, prepared for a long vigil.

“We believe that Jesus, the presence of Christ, needs to be at every execution,” Father Philo explained to reporters. The church members positioned themselves behind a wooden sign marked “Opponents” and began praying with signs containing Bible verses and quotes like “Thou shalt not kill.” Floridians for Alternatives to the Death Penalty also attended, working alongside the church group to make their opposition heard. Grace Hannah, an organizer for FADP, told reporters, “None of us are going to wake up tomorrow and be safer because David Pitman is dead.”

Inside the prison, a different scene was unfolding. Polk County Sheriff Grady Judd had traveled to Raiford to witness David’s execution personally. Judd had been one of the first responders to the Knowles house fire in 1990 and had waited 35 years to see justice carried out. Marie Pitman, David’s ex-wife, attended the execution along with other family members of the victims.

At 6:00 p.m., the execution procedure began. David was strapped to a gurney in the execution chamber and connected to the lethal injection apparatus. The state used its standard three-drug protocol: a sedative to render him unconscious, a paralytic to stop his breathing, and a drug to stop his heart.

David’s final words reflected his lifelong insistence on his innocence. “I know you all came to watch an innocent man be murdered by the state of Florida. I am innocent. I didn’t kill anybody. That’s it.” As the lethal drugs were administered, David took a few deep breaths before becoming still. Witnesses reported that the procedure proceeded without complications.

At 6:12 p.m., David Joseph Pitman was pronounced dead, becoming the 12th person executed in Florida in 2025 and setting a new record for the state.

Outside the prison, the protesters had fallen silent at 6:00 p.m. when the execution began. At 6:15 p.m., just after David’s death, a ray of sunshine pierced through the clouds above the prison, creating rainbow-like colors in the sky. The church members interpreted this as a sign that God was present during the execution.

Sheriff Grady Judd emerged from the prison to address reporters, flanked by surviving family members. He held up David’s 1990 mugshot next to a family photo of the Knowles family, telling reporters, “I want you to see, not the guy today, but I want you to see the guy that we arrested back in 1990. He was evil then. He was evil to the end. His last public statement was a bold-faced lie. He never changed.”

Marie Pitman, who had endured 35 years of legal proceedings since her family was murdered, told Sheriff Judd after the execution, “Now I can move on.” James Geddes, nephew of Barbara and Clarence Knowles, served as the family spokesman. “Today has brought a measure of closure to this tragic event 35 years ago. Justice has been served. These were good people who were dearly loved by their extended family.”

Floridians for Alternatives to the Death Penalty issued a statement condemning the execution: “Tonight, we the people of the state of Florida killed David Pitman, an intellectually disabled man. We killed a man who was broken and beaten as a child. A child his own mother described as one that no mother would want.”

David’s execution marked the 31st in the United States in 2025, representing a 10-year high, largely driven by Florida’s record-breaking pace. With David’s death, Florida had executed 118 people since the death penalty was reinstated in 1976.

The case concluded with the same questions that had haunted it for 35 years. Did the state execute a man whose intellectual disability should have protected him from the death penalty? Were the brutal murders of the Knowles family the product of a damaged mind that deserved treatment rather than execution? These questions would continue to resonate long after David Pitman’s voice was silenced forever.

As the protesters packed up their signs and the witnesses returned home, the David Pitman case entered history as one of Florida’s most controversial executions—a reminder of the complex intersection between childhood trauma, intellectual disability, and society’s ultimate punishment.

The story of David Joseph Pitman reminds us that justice, even when delayed, eventually arrives. Three lives were stolen in one night of unimaginable violence, and decades of appeals could not erase that truth.
