A 4-year-old girl threw herself between her mother and a knife. She didn’t run. She didn’t hide. At 4 years old, she turned toward the blade, not away from it. That child’s name was Hennessy Mullings, and on the night of June 27th, the year 2000, she became the youngest victim in one of the most disturbing murder cases in Florida’s modern history.

 The man who killed her had been living inside that apartment for weeks. He ate their food. He slept under their roof. He was family. And when it was over, when the screaming stopped and the lights went dark, he climbed out through a window, walked about 100 m, hid in the bushes, and told police he had been out jogging.

 He had fresh wounds on his hands. He had blood on his shirt. He had the audacity to lie. His name is Richard Andrew Knight, a Jamaican immigrant who arrived in the United States in 1998, overstayed his welcome in this country, and on one night in June 2000, ended three lives in a matter of minutes. Three lives because Hennessy’s mother, Adacia Stevens, was 6 weeks pregnant at the time of the attack.

 For 26 years, Richard Knight fought the state of Florida through appeal after appeal, claim after claim, insisting he was innocent, insisting the system had failed him. And on May 21st, 2026, at exactly 6:13 in the evening, the state of Florida answered. Hit subscribe, turn on the notification bell so you won’t miss our deep dive drops, and stay with me because what happened in that apartment that night, what was uncovered during the investigation, what was revealed at trial, and what took place in Knight’s final hours on this earth, none of it is easy to hear, but

it needs to be told for Hennessy, for Adacia, and for the child who never got to take a first breath. Before we step inside that apartment on the night of the murders, you need to understand who Richard Andrew Knight was and how he ended up there. Knight was born in Jamaica, according to court records.

 He did not grow up in a stable household. As a toddler, his biological mother abandoned him on a bus. A stranger found him and brought him to a police station. No one knew his name. No one knew his exact age. He was assigned a placeholder birthday, July 6th, 1978, and a placeholder name, Mark, while he sat in institutional care.

 A child with no identity, no family, no history. He was eventually taken in by a family that raised him as their own. But the damage of those early years ran deep. Court records indicate that between the ages of 8 and 11, he endured repeated sexual abuse at the hands of a neighbor. He later developed a seizure disorder, experienced chronic severe headaches, and suffered blackouts that his attorneys would later argue went untreated for decades.

In 1998, Richard Knight immigrated to the United States. He did not return when his visa expired. He remained illegally and almost immediately began accumulating a record that would signal exactly what kind of man he was becoming. Before the night of the murders, Knight had already faced serious accusations.

 He had been accused of indecent sexual assault against a 16-year-old girl. He had been accused of physical assault against a 12-year-old child. He had no employment, no stable income, no permanent home. By June of the year 2000, Richard Knight had reached a point that many people who knew him could see coming, desperation without direction, and a temper that had already demonstrated its reach.

 That was when he turned to the one person who had not yet closed their door on him, his cousin. Hans Mullins lived in Coral Springs, in Broward County, Florida, a quiet residential area near Fort Lauderdale. He shared his apartment with his girlfriend, Adacia Stevens, a 24-year-old woman described by those who knew her as warm, protective, and deeply devoted to her family.

 Adacia and Hans had a daughter together. Her name was Henecia Mullins. She was 4 years old, and at the time of the murders, Adacia Stevens was 6 weeks pregnant. When Richard Knight came to them with nothing, no money, no job, no place to go, Hans Mullins allowed his cousin into the home. It was a gesture of family loyalty, a decision made with the best intentions, but from the very beginning, Adacia did not want Richard Knight there.

She saw something Hans may have been unable to see in his own cousin. She felt the tension. She witnessed the behavior. She knew that having a grown, unemployed, directionless man living in a small apartment with a toddler and a pregnancy was not something she could accept long-term. The arguments between Adacia and Knight grew frequent.

 They centered on the same recurring issue, Knight’s failure to contribute, his refusal to make plans to leave, and Adacia’s growing insistence that he do so. The household had become a powder keg, and on the night of June 27th, 2000, Hans Mullins was not home. He was at work. At approximately 9:00 p.m. that evening, Hans called the apartment and spoke briefly with Adacia.

She told him she was getting ready for bed. She told him Richard was still inside the apartment. That was the last time Hans Mullins ever heard Adacia Stevens’ voice. What happened inside that apartment in the hours that followed has been reconstructed through physical evidence, crime scene analysis, and the testimony presented at trial.

 It is not easy to describe, but it is necessary. Sometime after that final phone call, Adacia Stevens made a decision. She had had enough. She was going to tell Richard Knight that night that it was time for him to leave, not tomorrow, not next week, tonight. She went to him. She told him directly. What followed was not a calm conversation.

 A heated verbal exchange erupted, and then, without warning, Richard Knight reached for a knife and attacked Adacia. What happened next is the detail that, even after 26 years, remains the hardest to process. Little Hennessey woke up. She was 4 years old. She saw a man pulling a knife on her mother, and rather than run from the room, rather than hide under her bed or scream from a distance, that child moved toward him.

 She threw herself at Richard Knight in an attempt to protect her mother. He stabbed her multiple times. After killing the child, Knight turned back to Adacia. Wounded, terrified, and fighting for her life and for the life of the unborn child she was carrying, Adacia managed to move to the kitchen. She tried to reach another knife.

 A struggle broke out between them. According to court records, the first knife broke during the attack on Hennessey. Knight retrieved a second knife and used it to continue the assault on Adacia, who had crawled to the living room. He overpowered her. He stabbed her repeatedly until she stopped moving. Three lives ended in that apartment that night.

 Adacia Stevens, 24 years old, her unborn child, 6 weeks along, and Hennessey Mullins, 4 years old, who in her final moments acted with a bravery most adults would never find, the apartment fell quiet. Richard Knight turned off the lights, pushed open a window, pulled the curtains back, and climbed out into the night. At 12:21 in the morning, a neighbor living in the unit above dialed 911.

 He had been hearing it for a while, loud banging from below followed by the desperate screams of a woman and what sounded like a small child. By the time Officer Vincent Saxes arrived at the building, just 8 minutes after that call, the screaming had stopped, but not everything was still. Officer Saxes observed lights on in the master bedroom and the hallway of the apartment. He knocked, no answer.

 He walked around the perimeter of the building. By the time he completed that loop, he noticed something that told him everything he needed to know. The lights inside had been switched off, and a window that had previously been slightly open was now fully open, with the curtains hanging outward. Someone had just left through that window.

 The officer shone his flashlight inside. Blood in the dining room, blood in the master bedroom. He entered the apartment. He found Hennessy Mullings first. She was curled in a fetal position beside a closet door. Then he found Idessia Stevens in the living room. Within minutes of that discovery, a second officer conducting a sweep of the surrounding area spotted a man crouching near some bushes approximately 100 m from the building.

She approached him. His name, he said, was Richard Knight. He claimed he lived in the apartment but had no key and hadn’t been inside for some time. He claimed he had been out jogging. He was wearing regular clothes and athletic shoes. His story might have seemed plausible to someone who hadn’t looked carefully, but this officer looked carefully.

 There were scratches across his chest, fresh wounds on his hands, and blood, visible, undeniable blood staining his shirt. Less than an hour after the attack, Richard Andrew Knight was taken into custody. Inside the apartment, crime scene investigators recovered multiple blood stained knives, the weapons used to kill both victims.

 Forensic analysts found skin cells beneath Idessia Stevens’ fingernails, evidence that she had fought back, clawing at her attacker in her final moments. DNA testing would tie that evidence directly to Knight. There was, however, one piece of evidence that Knight’s defense would later seize upon, a latent fingerprint found on the blade of one of the murder weapons.

 That fingerprint did not match Richard Knight. As of his execution date, that print has never been conclusively identified. Knight’s attorneys argued this was proof of reasonable doubt. Prosecutors argued the totality of evidence, the DNA, the blood on his clothing, the wounds on his hands, his presence at the scene, his flight through the window, left no doubt about what had happened in that apartment. Richard Andrew Knight Jr.

 was formally charged on August 15th, 2001, with two counts of first-degree murder in the deaths of Edecia Stevens and Hennessy Mullings. Because Edecia was pregnant at the time of the attack, prosecutors argued that three lives have been taken. Though legally, the charges centered on the two confirmed victims.

 The evidence against him was described by investigators as overwhelming. Yet the trial did not begin until 2006, nearly six years after the murders. Florida’s legal process, particularly in capital cases, is methodical and frequently delayed by pre-trial motions, evidentiary hearings, and the sheer volume of documentation involved.

 When the trial finally began, prosecutors laid out a case built on physical evidence, witness testimony, and forensic analysis. They presented the blood stained clothing, the DNA from beneath Edecia’s fingernails, the timeline of Knight’s movements that night, the eyewitness account of the officer who found him hiding in the bushes, bleeding, lying about jogging at midnight.

 The jury deliberated and returned a verdict of guilty on both counts of first-degree murder. In March of 2007, Richard Andrew Knight Jr. was sentenced to death. The Florida Supreme Court, in upholding the conviction, described the nature of the crimes using language rarely deployed in legal documents. The murders were ruled to have been heinous, atrocious, and cruel.

Knight maintained his innocence. He pointed to the unidentified fingerprint. He pointed to what his attorneys described as an incomplete picture of his mental health history and traumatic childhood presented at the sentencing phase. He argued the jury never heard the full story of his life, the abandonment, the abuse, the neurological issues, the seizures.

 The courts heard those arguments and rejected them repeatedly. Richard Knight spent nearly two decades on death row at Florida State Prison near Stark, Florida. During that time, he filed appeal after appeal in state court, in federal court, all the way to the United States Supreme Court. His legal team challenged the constitutionality of his sentencing.

They challenged Florida’s lethal injection protocol, arguing that a provision allowing prison staff, without formal medical training, to perform an invasive venous cutdown procedure without anesthesia, if four access could not be established, constituted cruel and unusual punishment under the 8th Amendment.

 That concern was not purely theoretical. Just hours before Knight’s scheduled execution, the state of Tennessee halted the execution of another death row inmate, Tony Carruthers, because prison personnel had been unable to establish intravenous access, precisely the scenario Knight’s attorneys had been warning about for weeks. Knight’s legal team filed an emergency stay application to the Florida Supreme Court, citing Carruthers’ case as proof of the risk the court declined to intervene.

 South Supreme Court denied Knight’s final petitions that same afternoon. On a personal level, Knight had reportedly found religious grounding during his years on death row. He identified as a follower of the Hebrew Israelite faith and expressed belief in Yahweh. Whether that faith represented genuine transformation, or simply the refuge that extreme confinement often produces in the human mind, is a question no one outside his own conscience could answer.

What is documented is this. He maintained his claim of innocence until the end, and he faced his death, by all accounts, without visible fear. May 21st, 2026 began like any other day inside Florida State Prison, with the particular institutional quiet that those walls have known for decades. Richard Knight woke at 5:00 in the morning.

 He showered. He spent the day largely alone. No family members visited. No relatives made the journey to be present in those final hours. No one came. When prison staff informed him he could order a last meal, a custom extended to every death row inmate in Florida before execution, Knight refused it. He declined the standard prison meal as well.

 He also turned down the offer of a spiritual advisor who could have been present with him in his final moments. He made those choices alone. At approximately 5:30 in the evening, Knight was transferred from his holding cell to the execution chamber. At precisely 6:00 p.m., the scheduled execution time, the curtain to the death chamber was raised.

Knight was already strapped to the gurney, arms extended outward, and intravenous lines secured in place. The room held prison officials, a physician, and a small group of authorized witnesses. The warden stepped forward. “Do you wish to make a final statement?” Richard Knight looked up, and he spoke four words.

 “I want to give thanks to Yahweh, the most high.” That was all. The execution began immediately. Knight closed his eyes. He barely moved as the three-drug protocol entered his system. First, the sedative, then the paralytic agent, then the agent that stopped his heart. After approximately 10 minutes, a physician entered the chamber, conducted a brief examination, and made the official pronouncement.

 Richard Andrew Knight, 47 years old, was declared dead at 6:13 p.m. He was Florida’s seventh execution of 2026, carried out under a pace of capital punishment that Amnesty International had, just days earlier, specifically cited as among the most aggressive in the developed world. Governor Ron DeSantis had overseen 19 executions in 2025 alone, a single-year record in Florida since the death penalty was reinstated in 1976.

No one from Knight’s family was in that room. No one was there for him. The contrast to the crime itself, to the family shattered in a Coral Springs apartment 26 years prior, was not lost on those who covered this case. Hans Mullins lost his girlfriend, his daughter, and his unborn child in a single night.

 He lost them to someone he had welcomed into his home. Hennessy Mullins was 4 years old. She acted, in her final moments, with more courage than most of us will ever be called to demonstrate. Odessia Stevens was 24. She had her whole life ahead of her, a family she was building, a child she was carrying, a future that ended on a kitchen floor because a man she asked to leave refused to go quietly.

 Their names deserve to outlast his. This case is a reminder, as so many cases on this channel are, that evil does not always arrive wearing a warning sign. Sometimes it arrives wearing the face of a relative. Sometimes it walks through a door you open yourself. And sometimes the most dangerous person in the room is the one who believes the rules simply do not apply to them.
