On April 8th, 2025, almost exactly 25 years after he killed Miami Herald worker Janet Aosta, Michael Anthony Tanzy was executed by lethal injection at Florida State Prison in Rayford, Florida. He was 48 years old. Before the drugs entered his veins, he ate one last meal. And then a man who once told detectives he killed because he was having too much fun opened his mouth one last time.

 What came out was not what anyone expected. But before we get to that, we need to talk about her because Janet Aosta didn’t die quietly. She died terrified, bound, and alone on the side of a road in the Florida Keys on what was supposed to be her lunch break. She had worked at the same newspaper for 25 years. She was just reading a book in her van and a stranger walked up and knocked on her window.

That moment changed everything. This is her story and his Janet Aosta was the kind of person who showed up every single day for 25 years. She worked in the layout department of the Miami Herald, one of the most recognized newspapers in the country. Her job was to decide where stories went on the page, where the ads landed, how the whole paper came together.

 She wasn’t flashy. She wasn’t looking for attention. Her coworker and close friend Carolyn Green described her simply. Janet was the nicest person you’d ever want to meet. On April 25th, 2000, a Tuesday, Janet went on her lunch break. She drove to the Japanese garden on Watson Island, a small, quiet spot in Miami she loved. She parked her van.

 She pulled out a book. She was just reading. She never came back. When she didn’t return from lunch, her co-workers started to worry. They pulled her personnel records. And then they noticed something strange. Her bank card had been used in Key West. Key West is over 160 miles away from Miami. Something was very wrong.

 Here’s what the court records tell us happened that afternoon. A 23-year-old man named Michael Anthony Tanzy walked up to Janet’s van. He asked her for a cigarette just like that. Casual, simple. And then without warning, he punched her in the face. He grabbed her wrist. He pressed a razor blade against her and threatened to cut her from ear to ear if she didn’t cooperate. Janet was terrified.

 She complied. Tanzy got behind the wheel of her van and started driving south. He made a stop at a gas station in Homestead about 30 mi south of Miami where he bound her hands and gagged her with rope. He drove further south. He forced her to perform sex acts. He threatened her again. He stopped at a bank and used her ATM card to drain money from her account.

 He stopped at a hardware store and bought duct tape and razor blades. And then he kept driving past Miami, past the city limits, past Homestead, down into the Florida Keys, one of the most remote stretches of road in America. The drive took hours. Janet was bound. She was gagged. She was in the back of her own van.

 And then on an isolated stretch of Kajjo Ki, roughly 20 miles from Key West, Tanzy stopped the van. He told her he was going to kill her. And then he strangled her. When she struggled, he stopped, placed duct tape over her mouth, her nose, her eyes, and then he strangled her again until she was gone.

 He buried her body in a secluded area covered by mangroves. Then he got back in her van and he drove to Key West. The whole ordeal from the moment he approached her van to the moment she died lasted approximately 4 hours. What did Tanzy do after killing Janet Acasta? He went shopping. He bought new clothes. He bought food. He bought marijuana.

 For 2 days, he lived freely in Key West, spending her money, wearing new things, eating well. On April 27th, 2000, 2 days after the murder, police spotted him getting into Janet’s van in downtown Key West. They arrested him on the spot. When detectives asked him why he killed her, Tany didn’t hesitate. He said, “If I had let her go, I was going to get caught quicker. I didn’t want to get caught.

 I was having too much fun. After his arrest, investigators learned something else. Something that changed the entire profile of who Michael Tanzy was. He confessed to another murder. 8 months before Janet Aosta was killed. On August 11th, 1999, a 37-year-old mother of two named Caroline Holder was working her shift at a coin laundry in Brockton, Massachusetts.

 She was stabbed and strangled. Her body was found at the laundromat. The case went cold. After Tanzy’s arrest in Florida, he confessed to killing her, too. He was never charged for Caroline Holder’s murder. He was never extradited. He never stood trial for what he did to her because his death sentence in Florida meant he was already facing the ultimate punishment.

A Miami police detective named Frank Kasanovas put it plainly. What we have here is a fledgling serial killer. Two women, two states, both strangled. Both killed within months of each other. Caroline Holder’s family never got a trial, never got a conviction, never got to sit in a courtroom and watch justice move.

 They got a confession and that was it. Now, a quick look at who Michael Tanzy was before all of this. He was born on February 27th, 1977 in the suburbs of Boston. His childhood, by all accounts, was brutal. His father was physically abusive and became more violent as he was diagnosed with pancreatic cancer. One of Tanzy’s childhood friends said his father once slammed his head into the side of a truck.

 His father died when Tany was around 8 years old. After that, a teenager in his neighborhood began sexually abusing him. This continued for years. His mother struggled to be present. Tanzy had problems in school, academically, and socially. He fought with other kids constantly. He couldn’t hold himself together. By the time he was a young adult, he had been diagnosed with PTSD, polyubstance dependence, ADHD, antisocial personality disorder, and several other conditions.

 At 21 years old, he was arrested in Brockton for stealing a van, and breaking into a home. He was sentenced to 18 months, but served only six. He was released in August 1999. Within days, Caroline Holder was dead. Eight months later, Janet Aosta was dead. His defense would later argue that his childhood trauma shaped him into who he became, that the abuse he suffered as a child left him fundamentally broken.

The court heard all of it. The jury still voted unanimously for death. Tanzy was indicted on some of the most serious charges Florida law allows. firstdegree murder, carjacking with a weapon, kidnapping with intent to commit a felony, armed robbery with a deadly weapon, two counts of sexual battery with a deadly weapon.

 He initially pleaded not guilty. Then, shortly before trial, he changed his plea. He pleaded guilty to first-degree murder, carjacking, kidnapping, and armed robbery. The penalty phase went to a jury. They deliberated and they came back unanimous. Every single juror recommended death. The judge agreed. In 2003, Michael Anthony Tanzy was formally sentenced to death. He was 26 years old.

He would spend the next 22 years on death row. Over the next two decades, Tanzy’s legal team filed appeal after appeal. They challenged the constitutionality of his sentence. They argued procedural errors. They sought federal habius relief. Denied. They went to the 11th Circuit Court of Appeals. Denied.

 They even challenged his sentence under Hurst versus Florida, a landmark case that changed how Florida handles death penalty juries. The Florida Supreme Court reviewed it and found the error in Tanzy’s case was harmless beyond a reasonable doubt. Every door was closed. And then on March 10th, 2025, Florida Governor Ron De Santis signed Tanzy’s death warrant.

Execution date, April 8th, 2025. In the weeks that followed, Tanzy’s lawyers made one final unusual argument. They argued he shouldn’t be executed because of his body. Tanzy, listed in court documents as 6′ 3 in tall and weighing up to 383 lbs, was described as morbidly obese with severe chronic sciatica, a painful nerve condition affecting his back.

 His lawyers argued that forcing him to lie flat and be restrained for lethal injection would cause him extreme pain before the drugs even began. They argued his size might prevent the sedative from working properly, meaning he could potentially feel everything. Being in this position and suffering severe sciatic nerve pain would require the Department of Corrections to torture him simply to establish and maintain two working intravenous sites.

 The defense wrote, “The Florida Supreme Court rejected the argument in a 23-page opinion, calling the claims untimely and meritless, noting Tany since at least 2009. His team then went to the US Supreme Court with an emergency petition to stay the execution. On April 8th, 2025, just after 3 p.m.

, the Supreme Court denied it. No dissents, no comment. Three hours later, Tanzy was strapped to a gurnie. The Florida Conference of Catholic Bishops had written to Governor Dantis asking for mercy, asking that his sentence be commuted to life without parole. They cited his childhood trauma, his abuse, his broken upbringing. Dantis did not respond publicly.

 The execution moved forward. On the morning of April 8th, 2025, Michael Tanzy woke up at 4:45 a.m. Florida Department of Corrections spokesman Ted Verman confirmed it simply. Inmate Tanzy woke up this morning at 4:45 a.m. He was provided his last meal and he has remained compliant. His only visitor that day was a spiritual adviser.

 No family, no friends, just a minister and silence. Outside the prison, around 70 protesters gathered on the lawn, holding signs, holding candles, holding each other. Some came to protest the execution. A few came to support it. Inside the prison walls, the machinery of the state moved quietly forward. His last meal, Tanzy requested a fried pork chop, bacon, a baked potato, corn, a soda, ice cream, and a candy bar, a full heavy meal. He ate it.

 He met with his spiritual adviser, and then he waited. At 6:00 p.m., witnesses were escorted into the viewing room adjacent to the execution chamber at Florida State Prison. There were 24 people in the room. among them Janet Aosta’s sister Julie Andrew, her niece Jennifer Vanderweir. They had waited 25 years for this moment.

 Staff from the Florida Department of Corrections instructed all witnesses to remain completely silent throughout the procedure. Michael Tanzy was already inside the chamber. He was lying on a gurnie covered almost entirely by a white sheet with only his left arm exposed. That’s where the intravenous lines were placed. Despite the defense’s concerns about his eyes, the lines were established without complication before the first drug was administered.

 The team warden prompted Tany for any final statement. His voice came through a speaker in the witness room. Low, measured, unemotional. He said, “I want to apologize to the family of Janet Acasta and Caroline Holder for taking their lives.” He paused and then he recited a verse from the Bible. Luke 23:34, the same words Jesus spoke from the cross.

 “Heavenly Father, please do not blame those who do not know what they’re doing.” No one in the witness room reacted. The room stayed silent. Then the executioner entered the chamber. Florida uses a three drug protocol. First, a sedative to render the person unconscious. Second, rockuronium broomemide, a paralytic to stop muscle movement.

 Third, potassium acetate to stop the heart. Roughly 3 minutes after the first drug was administered, Tanzy’s chest began to palpitate. It fluttered. Three prison staffers stood inside the chamber watching. The team warden stepped forward, leaned over the gurnie, and called out Tanzy’s name loudly twice to confirm unconsciousness. No response.

 The female executioner returned to the chamber. At 6:12 p.m., the team warden spoke through the speaker into the witness gallery. The sentence of the state of Florida versus Michael Tanzy has been carried out at 6:12 p.m. Michael Anthony Tanzy was dead. There were no apparent complications. It was the third execution in Florida in 2025.

 The 11th in the United States that year. Janet Aosta’s sister, Julie Andrew, was in that room. She watched every second of it. After it was over, she walked out of Florida State Prison and said, “It’s over. It’s done. Justice for Jana happened.” My heart just felt lighter and I could breathe again. 25 years. She had been carrying that weight for 25 years.

 Janet’s coworker and friend, Carolyn Green, who had worked alongside Janet at the Miami Herald for years, said simply, “It makes me want to cry. That’s why I haven’t spoken about it. Janet was the nicest person you’d ever want to meet. For Caroline Holder’s family, the woman killed in Massachusetts, there was no trial, no conviction, no courtroom moment.

 But Tanzy’s apology in those final seconds was the closest thing they ever got to an acknowledgement. Whether that was enough, only they can say. In the years leading up to his execution, Tanzy corresponded with a pen pal. In one letter, he wrote, “I’ve taken full responsibility for my actions, and I’m feeling content. Prison saved my life.

 I would have never made it to 30 years old. I thank God for re-entering my life and giving me the opportunity to find balance and change through his word.” He also believed that life without the possibility of parole would have been a more fitting punishment than death. Whether that belief came from genuine reflection or from a desire to stay alive is something no one can know for certain. What we do know is this.

 Two women are dead. One man is dead. And the question of whether justice was served is one people are still arguing about today. Janet Acasta went to her favorite spot on her lunch break. She was reading a book. She had worked at the same newspaper for 25 years. She was 49 years old. She had done nothing wrong.

 And in the span of 4 hours, everything was taken from her. Michael Tanzy spent 22 years on death row. He was fed, housed, given legal representation, and given the chance years and years to reflect on what he had done. Janet Aosta had no such time. Caroline Holder had no such time. And now Michael Tanzy is gone, too.

 The state of Florida called it justice. His defense called it revenge. The Catholic bishops called it unnecessary. Janet’s sister called it relief. And the question this case leaves behind, the one that no execution can fully answer, is this, when someone takes a life, what does justice actually look like? And is there any sentence, any punishment, any outcome that can truly give back what was lost? Think about that.
