Florida to EXECUTE ZIELER, Killed 2 Women in 1990,Moved in With Girlfriend & Lived FREE for 26 YEARS
“What’s that? Which one right here? All right. All right. I ain’t doing nothing to you. Relax. I’m calm. Zieler, are you okay? I’m fine. All right, relax. I’m calm. Relax. I used to box. I’ve taken a lot better shots than that. Yeah, I’m not messing. Relax. Relax. Don’t do that. You know, relax. I ain’t doing nothing to you. Relax.”
On the night of May 9th, 1990, a mother kissed her daughter goodnight, told her she loved her, and drove 5 minutes down the road to her boyfriend’s house. She fell asleep on the couch. When she woke up at 4:00 in the morning and drove home, both locks on her front door were engaged. She knocked. From inside her own apartment, she heard footsteps coming down the stairs. Nobody opened the door. She walked around to the back of the unit. The sliding glass door was wide open.
What she found inside that apartment would define the next 33 years of her life. Two women were dead, her daughter and her friend, gone in a single night in a home that was supposed to be safe in a city where nothing like this had ever happened before.
The killer left behind one thing he could not take with him: his DNA. And for 26 years, it sat in an evidence file with no name attached to it. He went back to his life. He got a girlfriend. He moved in down the road. He worked as a landscaper. He watched the anniversary news coverage every May and kept cutting grass. It took a pellet gun argument, a 2009 Florida law, and a national database to finally put a name to what had been waiting in that evidence file for over two decades.
What followed was one of the longest cold cases in Cape Coral history, a trial 33 years in the making. A courtroom performance so bizarre, it became part of the story itself. And a mother who made a promise at her daughter’s graveside and spent the next three decades making sure she kept it.
To understand how two women lost their lives on a quiet Thursday night, and how the man responsible lived freely among the same community for 26 years, we have to go back. Back to a household built on fear and violence. Back to a criminal record that started in the 1980s and never really stopped. Back to the very beginning of Joseph Zieler.

Joseph Adam Zieler was born in 1962 in Florida. His father, Robert Zieler, was a Cape Coral police officer. From the outside, the family looked like any other. A man with a job, a wife, a son growing up in a Florida neighborhood. But what happened inside that house was very different from what the neighbors saw. Robert Zieler was violent at home. He used physical force to control his family. For Joseph, growing up in that house meant living in constant fear of his own father. Not sometimes, every day. Fear was simply the air he breathed inside those walls.
His mother, Joanne, did nothing to change that. She showed no warmth and no affection toward her son. There was no safe side of the house to retreat to. Joseph had nowhere to go and no one to turn to. A psychiatrist who studied his background would later explain what that kind of upbringing does to a person. When a boy grows up watching his father use violence to get what he wants, he does not learn right from wrong. He learns that the person with power makes the rules. He learns that force is how problems get solved, and he learns that lesson every single day, whether anyone is teaching it to him or not.
Joseph had difficulty concentrating in school. He struggled to pay attention and to reason through problems. He passed his grades, but tests given to him decades later showed serious gaps in memory, in verbal reasoning, in his ability to shift from one thought to another. These were not new problems. They started early in a home that gave him nothing to build on.
By the time he was a teenager, the damage was showing up in public. He was arrested for grand theft auto and burglary. He was not stealing to survive. He was stealing because he had grown up learning that taking things from others was simply how the world worked. He had watched someone do it to his own family for years. The arrests did not stop. They got worse.
Through the 1980s, Joseph Zieler built a criminal record that followed a clear path. First, it was theft. Then it became more direct: battery, battery on a police officer, carrying a concealed weapon, dealing in stolen goods, resisting arrest with violence. He was no longer just taking things quietly. He was now willing to fight anyone who tried to stop him, including the police. Some charges were dropped. Others resulted in convictions, but none of the penalties kept him locked away long enough to change anything. He went in, he came out, and he went back to the same streets in Lee County, Florida.
He had figured out where the system’s limits were, and he stayed just inside them. He also had outstanding arrest warrants from Maryland and Chicago, problems he had simply left behind in other states and never dealt with. Police in Florida stopped him five times over the years in connection with the Chicago warrant. He walked away each time.
By the late 1980s, the Cape Coral and North Fort Myers area was his home ground. He knew the neighborhoods well, the apartment complexes, the back roads, the bars, the layout of the city. Cape Coral in 1990 was a growing city of about 75,000 people. Quiet, mostly residential, the kind of place where families came home from work, made dinner, and left their back doors unlocked because nothing bad had ever happened to tell them not to.
Zieler paid close attention to those neighborhoods. He noticed things most people walked past: who came and went, when lights went on and off, which doors were left open at night. He moved through the residential areas of Cape Coral quietly, without drawing attention to himself. One of those areas was an apartment complex on Southeast 12th Avenue called The Courtyards of Cape Coral Condominiums.
Jan Cornell lived there with her younger daughter. In the evenings, she sometimes heard noises outside her windows that she could not explain. They had been keeping her up at night. Neighbors around the complex had also noticed a man hanging around the property at odd hours. He did not live there. Nobody recognized him. He would appear near the edges of the complex, standing still, and then be gone.
Then on the evening of May 9th, Jan walked to her upstairs bedroom window and looked down. A man was standing below in the dark, staring straight up at her. He did not look away. He stood there for several minutes, looking directly at her. Then he smiled, and then he walked away. Jan stepped back from the window. She did not know that man. He was not a neighbor. He was not someone she had ever seen around the complex. He was a complete stranger who had stood in the dark below her window, stared up at her without any shame, and then walked away as if it was nothing.
The noises outside had been going on for several nights already, sounds she could not explain, movement in the dark that kept her from sleeping properly. During the day, it was easy to brush those things off. At night, it was harder. The Courtyards of Cape Coral Condominiums sat on Southeast 12th Avenue, three blocks from Cape Coral Hospital. It was a quiet, working-class complex: nurses, secretaries, laborers. People who came home tired, made dinner, and went to bed. The kind of place where back doors were left unlocked because nothing had ever happened to make anyone think twice about it.
That same man standing outside was Joseph Zieler. He was 27 years old. He had no steady job that anyone in the area could later identify. He lived in North Fort Myers, just a few miles away. He had been watching the complex for several days, learning who came and went, when the lights went off, when things went quiet. His years of burglary had taught him exactly how to study a property. He knew how to find the open doors. He knew how to wait.
What Zieler did not know was that May 9th was not a normal evening at that apartment. Jan Cornell’s older daughter had recently moved out for college, leaving a spare room empty. Jan had mentioned at work that she wanted to rent it out to help cover expenses. Her colleague and friend at Cape Coral Hospital, 32-year-old Lisa Story, had expressed interest. Lisa needed a place. Jan had a room.
On the afternoon of May 9th, Lisa brought her boxes over and moved in. It was her very first day there. She had not yet spent a single night in the apartment. That evening, Jan had planned to stay home, but her daughter and Lisa both encouraged her to go and visit her boyfriend, Donnie, who lived nearby. Jan hesitated. She had an early shift at the hospital the next morning, but everyone was already settled for the night, and Donnie lived close. She decided to go for a few hours. She kissed her daughter goodnight. Her last words to her were, “Goodnight, I’m going to Donnie’s. I love you.” Her daughter told her to have fun. Jan got in her car and drove to Donnie’s house.
That daughter, the one Jan had kissed goodnight, was Robin. Robin Marie Cornell was born on November 30th, 1978 in Cape Coral, Florida. She was in fifth grade. She loved jumping rope, playing outside, and scary movies. She was not the kind of person who drew attention through noise or drama. She drew it through something genuine. The way she listened, the way she engaged, the way she made people feel noticed. Teachers remembered her. Classmates remembered her. Her mother described her as funny, caring, and full of love for everyone around her. She had already decided what she wanted to do with her life. She wanted to be a writer. For a girl her age, that kind of certainty was rare. Most young people change direction every few weeks. Robin had made up her mind and meant it. That night she was home in the apartment she had grown up in. Lisa was in the next room. Her mother was 5 minutes away. The evening had been quiet and ordinary in every way. She had no reason to feel anything other than safe. She went to sleep.
In the next room, Lisa Story was also settling in for the night. Though for her, nothing about the apartment was familiar yet. She had moved her boxes in just that afternoon. She did not yet know which stairs creaked or where the light switches were in the dark. It was her first night there.
Lisa Diane Story was born on September 15th, 1957 in Ohio to Donna Howitt and Kenneth Story. She was the youngest in her family. She had grown up in Ohio and eventually moved south to Florida, where she built a life in Cape Coral. She worked as a secretary in the fundraising department at Cape Coral Hospital, the same hospital where Jan Cornell worked, which was how the two women had become friends. Outside of work, Lisa was a motorcyclist and a photographer. She moved toward experience. She was someone who filled her life deliberately. She was also engaged to be married. Her fiance, Randy Richards, was the person she spoke to every day without exception. He described her as outgoing, loyal, and deeply proud of everything she had built. He said the effect she had on the people around her was difficult to put into words.
She had recently bought a Seiko wristwatch and had it engraved for Randy’s upcoming birthday. To Randy: “Happy birthday, 5/11/90. All my love, Lisa.” His birthday was 2 days away. The watch was somewhere in the apartment that night, not yet wrapped, waiting. It was never found. Lisa had a wedding to plan, a new home to settle into, and a birthday gift to give. She went to bed that night with all of it still ahead of her. She closed her eyes in her new room and went to sleep.
Jan woke up on Donnie’s couch at around 4:00 in the morning. The television was still on. The house was quiet around her. She had not meant to fall asleep. She had told her daughter she would be back, and she had not come back. She got up quickly, grabbed her things, and drove home.
When she pulled into the Courtyards complex and walked to her front door, she stopped. Both locks were engaged. The deadbolt and the lower lock. That was wrong. She had specifically told Lisa not to use the lower lock because Jan only had a key to the upper one. She knocked. She waited. From inside the apartment, she heard footsteps on the stairs. Nobody came to the door. Jan stood outside in the dark, listening to footsteps inside her own home, and the door did not open. She waited another moment, then walked around to the back of the unit. The sliding glass door was wide open. She stepped inside.
The kitchen light was on. The apartment she had left calm and tidy just a few hours earlier had been completely turned over. Drawers were open. Things were scattered across the floor. In the living room, the ironing board was standing open. Arranged on top of it were photographs. Photographs of her daughters taken from the shelf and placed there carefully, deliberately.
Jan ran upstairs. She found Lisa Story in her bedroom. Lisa was dead. Jan ran out of that room and into the master bedroom. Her daughter was on the floor, face down. Jan turned her over. Robin was cold. Jan got down onto the floor beside her and tried to revive her, calling for help at the same time, staying right there beside Robin until the first responders arrived.
Outside, Cape Coral was still dark and quiet. The neighborhood had no idea what had happened behind the sliding glass door of that apartment. The Courtyards complex looked exactly as it always did in the early hours of the morning. Inside, Jan Cornell sat on the floor next to her daughter and waited for the police to come.
The call brought Cape Coral police to the Courtyards complex before dawn on May 10th, 1990. Officers arrived to find a scene that told a story in fragments. The back sliding glass door had been the entry point. The kitchen and common areas had been searched. Drawers turned out, contents displaced. The photographs on the ironing board had been placed there by someone who took the time to do it deliberately before leaving.
In the upstairs rooms, investigators found both victims. Lisa Story had been suffocated in her bedroom. She had been dead for some hours by the time Jan found her. Robin was in the master bedroom on the floor with a pillow nearby. Both had been sexually assaulted. In the bathroom, investigators found footprints. On a dining room chair, they found a pair of white socks. Near the back door, they found four keys. The apartment had been searched thoroughly. The killer had moved through every room, taken time to look through belongings, and had been deliberate enough in what he did that the arrangement of the photographs carried its own particular weight.
Items were missing. Lisa Story’s driver’s license was gone. Her credit cards were gone. Her checkbook was gone. And the Seiko watch she had purchased as a birthday gift for Randy Richards, engraved with his name and her love, was gone, too. Randy’s birthday was in 2 days. The watch had been sitting somewhere in the apartment, ready to be wrapped. It left with the man who had been there.
The killer had taken a shower before he left. Investigators found evidence of this in the bathroom. He had moved through the apartment, committed what he came to commit, taken what he decided to take, cleaned himself up, and walked out the same way he had come in.
The crime scene also contained something the killer had not managed to take with him. His own biological material. DNA was present on Robin, on the bedsheet, and on the pillowcase. Investigators collected it carefully, packaged it, and entered it into the evidence record of a case that had no suspect, no name, and no clear direction.
Cape Coral police launched a full investigation. Officers canvassed the neighborhood, interviewed every person they could locate with any connection to the Cornells or the Storys. The community was in shock. Cape Coral was not a city that had experienced something like this. The murders of a woman and a young girl in their own apartment in the night by someone who left almost no trace except what the science would eventually find. It sat heavily over the city in a way that nothing quite dispersed. The investigation had a piece of the killer. It had his DNA. The Cape Coral Police Department had the lock, as investigators would later say. They just needed the key.
In the days following the discovery of the two bodies, the Cape Coral Police Department worked through the evidence systematically. The crime scene at the Courtyards apartment had given them more to work with than many homicide investigations begin with. Biological material, footprints, physical artifacts, but it had also given them no name, no face, and no clear motive. The evidence pointed to a specific sequence. The killer had entered through the unlocked back sliding glass door. He had moved through the downstairs first, searching through the apartment with enough time and calm to go through drawers and open cabinets. Then he had gone upstairs.
The order in which the two women were attacked was something investigators reconstructed from the physical evidence. Story appeared to have been encountered first in her bedroom. Robin had come to investigate and been confronted in the master bedroom. Both had been suffocated. Both had been sexually assaulted. The assault itself was the source of the biological evidence. Semen recovered from the bedsheet, the pillowcase, and from Robin. The DNA profile extracted from that material was clear. It was complete. It was the kind of profile that, given the right circumstances, could be matched to a specific person with statistical certainty so absolute that it exceeded the capacity of ordinary numerical expression.
In 1990, however, the national DNA database that would eventually make that match possible did not yet exist in its current form. The technology was new. The databases were thin. And without a suspect to compare the evidence against, the profile sat in storage, accurate, intact, and waiting.
Investigators did not wait passively. They worked through the social world of Jan Cornell and Lisa Story with methodical thoroughness. Every male connected to either woman was interviewed. Family members, colleagues, friends, former partners, neighbors. The apartment complex yielded its own set of interviews as residents described what they had noticed in the days before the murders. Jan had mentioned the peeping Tom to several people. That detail led investigators to a specific individual who had been seen in the area in the days before May 9th. They found the man. They investigated him. They cleared him. He was not the real killer. They were thorough enough to document that approximately six people had been in or around the apartment on May 9th during the time Lisa was moving in. Each of them was looked at. None of them produced a match to the DNA profile in evidence.
The investigation spread outward. Hundreds of leads came in over the following months. Tips from the community, names suggested by residents, information that filtered in through the networks of people who knew the victims. Each lead was followed. Each produced nothing. Joseph Zieler was not among the names that surfaced. He had no known connection to Jan Cornell or Lisa Story. He had not been to the apartment, had not worked with either woman, had not been introduced through any mutual acquaintance that investigators could locate. From the perspective of the original investigation, he did not exist in relation to this case.
Two months later, in July 1990, he was arrested in Lee County on charges of battery and battery on a law enforcement officer. The charges were eventually dropped. He walked out of the system again, free and untouched. Not long after that, he walked into a bar called Bumbershoots in Cape Coral. He sat down and met a woman named Bonnie Nicely. She was married at the time. Her husband moved out. Zieler moved in. Just like that, he had a home, a partner, and a new chapter of ordinary life. Weeks after committing two murders in the same city, he settled into the North Fort Myers area with Bonnie, who had a son. The two of them worked as landscapers and handymen. They lived at 314 Byron Avenue in North Fort Myers, an address Zieler would occupy for 20 years.
The city grew around him. The case remained open. The Cape Coral Police Department did not let it go. The case passed from one investigator to the next as careers progressed and people moved through the department. Each new detective assigned to the file familiarized themselves with the evidence, the profiles, the gaps. The DNA profile was entered into the state’s system as the technology developed. In the late 1990s, when new advancements in DNA comparison became available, the Cape Coral police submitted the evidence profile to be compared against the state database. There was no match. The profile waited.
The murder of Robin Cornell and Lisa Story did not fade from Cape Coral’s collective memory the way some cases do. The city was large enough to sustain ordinary life, but small enough that an event of this magnitude left a mark that people carried for years. Neighbors who had lived near the Courtyards complex in 1990 still remembered where they were when they heard. People who had moved to Cape Coral in the months after still remembered the headlines, “Cape Woman, Girl Slain”, as their introduction to the city.
Jan Cornell made sure the case stayed visible. She was not a person who accepted the passage of time as an excuse for silence. She kept Robin and Lisa present in the public conversation about unsolved crimes in Southwest Florida. She spoke to reporters on the anniversaries of the murders. She kept in contact with investigators. She was a familiar presence to the Cape Coral Police Department across multiple generations of officers, the kind of victim’s mother who becomes embedded in the institutional memory of a department not because she is difficult, but because her dedication is absolute.
On the 24th anniversary of Robin’s murder, Jan told a reporter, “I’ll never stop until I find out who hurt them.” She had been saying something like that for more than two decades. She meant it every time. The case appeared on America’s Most Wanted three times across the years. Each appearance brought new tips, new calls, new names. The investigators followed every credible lead that came from those broadcasts. None of them led to the man whose DNA was sitting in the evidence file.
Zieler was not a person whose name came up in the tip lines. He had no known connection to the victims. He had been living 20 minutes away for the entire period, raising a son, working as a landscaper, getting stopped occasionally by local police in connection with old warrants, and moving through ordinary life without detection.
In 2010, Detective Kirk Grow of the Cape Coral Police Department gave an interview to the Cape Coral Daily Breeze. He was precise about the state of the investigation. “We have the killer’s DNA,” he said. “It’s just a matter of getting the right person.” Grow had been on the case for years by that point. He knew the evidence file in detail. He understood exactly what they had and exactly what they were missing. The DNA profile was not degraded or uncertain. It was not the kind of evidence that raised questions about its reliability. It was simply waiting for a name.
The department’s chief investigator, Christie Joe Ellis, had been with Cape Coral Police for the better part of her career. She had come up in the department as the Cornell-Story case was already a defining element of its history. She prayed about it. She later said she had prayed every day for 26 years that the case would be solved. She believed it would be. She told people that. She had the lock, she said. She just needed the key.
In the years between 1990 and 2016, Joseph Zieler continued to live his life in North Fort Myers. He worked with Bonnie as a landscaper and handyman. Their relationship was marked by domestic violence and substance abuse. Bonnie did not know about the murders of Robin Cornell and Lisa Story. She knew Zieler had been arrested as a young man for stolen property, battery, weapons possession. She knew he could be violent. She knew the household had not always been safe. But she did not know what had happened in the spring of 1990, a few weeks before she met him at a bar called Bumbershoots.
Zachary, the son she had, grew up in the household. He knew his father as a man who beat him, who choked him, who threatened to kill him. He grew up with a man he later described as a monster. A person who inflicted physical harm as a regular feature of domestic life. Zachary believed for much of his childhood that Joseph Zieler was his biological father. He later learned otherwise. While all of this was happening, the case stayed open. The DNA waited.
In August 2016, Zieler got into an argument with Zachary. On August 27th, 2016, a call came into the Lee County Sheriff’s Office from Lee Memorial Hospital. A 25-year-old man named Zachary Zieler had been brought in by his girlfriend. He had a wound on his chest. A pellet had broken skin near his heart. He told the hospital that he had been in an argument with his father and that his father had picked up a pellet rifle and fired it at him. The pellet had nicked Zachary’s heart. He could not breathe well enough to drive himself and had been brought in by his girlfriend. The wound was serious enough to require medical attention and serious enough to produce a criminal investigation.
Joseph Zieler was arrested on a charge of aggravated battery with a deadly weapon. It was a felony under a Florida law that had been passed in 2009. Anyone arrested for a felony in the state was required to provide a DNA sample, which was then submitted to the National Combined DNA Index System, CODIS, and compared against the profiles in the database.
Zieler was booked into the Lee County Jail. A DNA swab was taken from him as part of the standard booking process for a felony charge. The sample was submitted to the Florida Department of Law Enforcement and entered into CODIS. The comparison ran against the millions of profiles in the database: unsolved crimes, convicted offenders, cold cases going back decades. Among those profiles was one that had been sitting in the system since the late 1990s, waiting. It was the DNA recovered from the Courtyards of Cape Coral Condominiums on the morning of May 10th, 1990.
The result came back: a match. FDLE notified the Cape Coral Police Department. Chief Investigator Christie Joe Ellis received the phone call. She later described what she felt when she heard it. She said it was so surreal that her first response was to say out loud, “Are you kidding me?” She had worked toward this moment for years. She had prayed for it. And when it came, it came from a direction no one had been watching. A pellet gun argument in North Fort Myers, an arrest for a crime that had nothing to do with the case she had spent a career on.
Cape Coral Police immediately moved to confirm the match. Detectives drove to Lee County Jail and interviewed Joseph Zieler the following day, September 22nd, 2016. They sat across from him and asked him about the murders of Robin Cornell and Lisa Story. He listened to the question. He did not show visible alarm and then he told the detectives that he had been in a motorcycle accident in 1998 and had sustained a brain injury that destroyed his memory of everything before that year. He said he had no memory of the period surrounding the murders. He did not know those women. He had never seen that apartment. He never once asked what had happened to them.
The detectives noted that detail. A person who is genuinely confused or distressed by an accusation of murder typically asks questions. What happened? When? Where? Who was it? Zieler asked nothing about the victims. He gave his answer about the motorcycle and offered nothing else.
After the interview, investigators secured additional DNA samples from Zieler: saliva and hair. Those samples were sent to FDLE for independent confirmation. While Zieler was still in the jail on the pellet gun charge, FDLE confirmed the second match. The DNA from the apartment on Southeast 12th Avenue, the biological material collected from Robin and from the bedsheet and pillowcase in the early morning of May 10th, 1990, belonged to Joseph Adam Zieler.
Police Chief David Nulan called a press conference. On September 28th, 2016, he stood before the cameras and said, “We got him.” Jan Cornell was at home when detectives came to her door to tell her. She later said there was no way to describe the feeling. “It was like winning the lottery of justice,” she said. “Every prayer, every word, everything came full circle.”
The arrest warrant for Joseph Zieler was signed on September 27th, 2016. He was charged with two counts of first-degree murder, two counts of sexual battery, and one count of burglary. He was held without bond. The following morning, he appeared in Lee County Court, showed no emotion, and was assigned a public defender.
But from inside the jail, he started making phone calls to Bonnie Nicely. Bonnie had spent 26 years with this man. She had lived with him, worked alongside him, and built her entire daily life around him. When detectives first came to her door about the DNA match, she was angry and devastated. She cooperated fully. She handed over letters Zieler had sent her from jail, letters that now made a terrible kind of sense. In one of those letters, he had written, “I can’t help what transpired before I met you. I can only say it stopped. It stopped because of you. If I lose you now, I’ll slip away back into what I once was. I don’t want this thing to creep back in and become violent again.”
The jail calls were recorded. In one of them, Zieler told Bonnie, “Back in 1990, I did go through this before and nothing bit me in the ass, so there’s a very good chance it won’t.” In another call, he talked about having a backpack and making an escape. When Bonnie confronted him directly about the DNA, he told her he was being framed. He could not explain how his DNA got there. He just kept telling her not to leave him. Bonnie ended the relationship in November 2016.
The DNA analysis confirmed the match across multiple samples. The probability that the DNA belonged to anyone other than Zieler exceeded 1 in 83 quintillion, a number so large that prosecutors told juries the human mind simply cannot hold it. In November 2016, a grand jury formally indicted Zieler on the murder charges. His public defender was eventually replaced by private defense attorneys, Lee Hollander and Kevin Shirley. The case that had waited 26 years for a name now had one. It entered the courtroom, where it would remain for the better part of seven more years.
Between Zieler’s arrest in 2016 and his trial in May 2023, seven years passed. Capital murder cases move slowly. The charges were serious, the evidence complex, and both sides needed time to prepare. Zieler sat in Lee County Jail through all of it. He was in his 50s and his health was declining. He also began writing letters to the Cornell family suggesting that a relative of his had committed the murders. When confronted about the letters, he first denied writing them, then admitted it and said he was defending himself. Jan Cornell received those letters. She had buried her daughter and spent 26 years fighting for justice. And now the man whose DNA was found on her daughter’s body was writing to her with alternative theories.
The pre-trial period also produced a significant legal problem. Jury selection began in February 2023, but the panel was dismissed after being given incorrect information about parole eligibility. A new jury was not seated until May 2023. That gap mattered. In April 2023, Governor DeSantis signed a new law reducing the death penalty recommendation threshold from unanimous to eight votes out of 12. Whether that new law applied to Zieler’s case became a question that would follow him into the appeals process.
In May 2023, a new jury was seated. The trial began. Jan Cornell walked into the Lee County Courthouse as the first witness for the prosecution, 33 years after finding her daughter on the floor of that bedroom. Jan took the stand on May 16th, 2023. She told the jury about her daughter: funny, caring, a lover of scary movies, a young person who had already decided she wanted to be a writer. She told them the last words she had said to her: “Good night. I’m going to Donnie’s. I love you.” Then she told them what she had found when she came home, the locked door, the footsteps, the open sliding glass door, the ransacked apartment, the photographs arranged on the ironing board, and her daughter on the bedroom floor.
Zieler sat a few feet away throughout her testimony, looking directly at her. He did not look at the photographs the prosecution placed before the jury. The prosecution kept their case simple. Three items: Robin Cornell, a pillow, and a bedsheet, all carried Zieler’s DNA. That was the case. DNA analyst Vicky Belino walked the jury through the technical details. The probability that the DNA belonged to anyone other than Zieler was 1 in 83 quintillion, a number so large that the FDLE stopped reporting beyond 1 in 700 billion because, as prosecutors explained, the human mind cannot process anything bigger.
The defense challenged the DNA on two grounds: that the evidence had been mishandled over 26 years, and that hair samples appeared to be missing from the evidence packaging, which they called tampering. Prosecutors responded that biological material is consumed during testing and that there was no evidence of interference. The defense also argued there was no motive. No prior connection between Zieler and the Cornells had ever been established. They suggested the attack felt personal, that whoever did it had a reason to target Jan specifically. They offered no alternative suspect.
The jury listened to both sides and the evidence continued. The prosecution built their case layer by layer. Officers who responded on the morning of May 10th, 1990, described exactly what they found: the open sliding glass door, the ransacked apartment, the photographs arranged on the ironing board, the biological evidence collected from the upstairs bedrooms, the footprints in the bathroom, the white socks on the dining chair, and four keys near the back door.
Detective Kristy Joe Ellis testified about the investigation, the hundreds of leads pursued over 26 years, the suspects interviewed and cleared, and the moment in 2016 when the CODIS match came in. She described getting that phone call as something she had prayed toward for her entire career.
The jury then watched the 2016 interrogation video. They saw Zieler sit calmly across from detectives and describe the motorcycle accident, the brain injury, the memory loss. He said he did not know the victims and had never seen their apartment. He never once asked what had happened to them. Deputy James Divins then testified that when he had interviewed Zieler on the day of the pellet gun arrest, before Cape Coral police connected the DNA, Zieler had said nothing about any memory problems. He spoke clearly, remembered his parents’ names, and mentioned that he had been with Bonnie for 25 years. The memory loss story only appeared when Cape Coral detectives arrived with questions about the 1990 murders.
Bonnie Nicely testified for 90 minutes. She confirmed Zieler had no memory problems across their entire time together. She could barely look at him. She read the letter he had sent her from jail, the one where he wrote that he feared what he might become without her, that violence was something he was trying to keep down. The jury heard the recorded jail calls. Zieler telling Bonnie nothing would bite him in the ass, talking about a backpack and an escape, insisting he was being framed when she confronted him about the DNA. Zieler, watching Nicely from the defense table, later called her a liar.
The defense pushed their tampering argument: missing hairs in the evidence packaging, too many hands on the evidence over too many years. Prosecutors responded that biological material is consumed during testing and that every step in the chain of custody was documented. There was no tampering. There was science.
After several days of testimony, Zieler made a decision that surprised everyone in the courtroom. He told his attorneys he wanted to take the stand. Joseph Zieler took the witness stand on May 18th, 2023. He was 60 years old, physically diminished by health conditions his attorneys had documented, but alert and deliberate in the way he answered questions. His defense attorney Kevin Shirley questioned him first. Zieler’s initial answers were composed. He said he did not know Robin Cornell or Lisa Story. He said he had never been in their apartment. He said he had never seen the photographs his attorneys showed him of the building and the unit. When Cape Coral detectives had shown him those same photographs during the 2016 interrogation, he said he had not recognized the location. He maintained that position on the stand.
He was asked about his whereabouts on the night of May 9th, 1990. He said he was in Maryland. He was asked about the DNA. This is where his testimony became something the courtroom had not anticipated. Zieler told the jury that it was not possible for his DNA to be at the crime scene in the way the prosecution described, but rather than simply denying the DNA was his, which the science made impossible, he offered an explanation. He said that several months before the murders, he had been in an intimate encounter with Jan Cornell. He said that was the only way his DNA could have found its way into that apartment, onto those surfaces, onto the victims.
The courtroom absorbed this. Jan Cornell had testified that she did not know Joseph Zieler. She had never met him, never seen him before his arrest. She had looked at investigators in 2016 when they showed her his name and photograph and told them she had no idea who he was. There was no connection between them, no professional relationship, no social overlap, no mutual acquaintance who could have placed them together. Zieler’s explanation required the jury to believe that a woman who claimed complete ignorance of his existence had actually been in an intimate relationship with him months before the murders. He offered no corroboration for this claim. He produced no witness, no communication, no detail that could be checked against any independent record. He then called Jan Cornell a pig, saying that if his DNA was on the bedsheet, it was because she did not wash her sheets. The jury was watching him.
Prosecutors then cross-examined Zieler. The exchange was heated from the beginning. They pressed him on everything. The DNA, his alibi claim of being in Maryland, the letters he had written to the Cornell family suggesting his relative had committed the murders. Zieler had initially denied writing those letters. When shown documentation proving he had written them, he admitted it and said he was defending himself. He confirmed he had addressed them to the entire Cornell family. He confirmed he had been convicted of five felonies. He confirmed outstanding warrants for Maryland and Chicago at the time of the murders and said he had been stopped five times in Florida in connection with the Chicago warrant. He said he had not been guilty of the assaults on the two women. “I knew they arrested the wrong person,” he said.
During cross-examination, Zieler had an outburst. He pulled a piece of paper from inside his jacket and thrust it toward the jury. The judge immediately intervened and reprimanded him sharply. Shirley said afterward that Zieler’s conduct on the stand did not help.
The defense rested its case after Zieler’s testimony. Closing arguments followed. Prosecutor Dan Feinberg asked the jury, in the closing moments of his argument, to think about the 60 to 70 seconds before Robin Cornell lost consciousness, the period of time before she was suffocated. He asked them to hold that in their minds. Defense attorney Kevin Shirley argued that the state had not proven beyond a reasonable doubt that the murders were premeditated, cold, and calculated. He argued for the possibility of reasonable doubt.
The jury went to deliberate. It took them approximately 3 hours. They returned a verdict on May 18th, 2023. Guilty on both counts of first-degree murder. Joseph Zieler was convicted of the murders of Robin Cornell and Lisa Story. After 3 hours of deliberation, the jury came back. Guilty on count one, guilty on count two. Two counts of first-degree murder proven beyond a reasonable doubt. As the verdict was read, Zieler turned toward the camera and smirked.
Jan Cornell was in the courtroom. Randy Richards was in the courtroom. They had both waited 33 years for this moment. Jan said they had lived in fear and sadness for all of it. Randy said he hoped Lisa and Robin were smiling a little more. Cape Coral Police Chief Anthony Sizemore said he was grateful the day had finally come.
The case now moved into the penalty phase. The jury would reconvene to decide between death and life in prison. Under Florida law, the prosecution first had to prove at least one aggravating factor beyond a reasonable doubt. If they cleared that bar, the jury would weigh those factors against whatever mitigating circumstances the defense presented before making their recommendation.
Under the April 2023 law signed by Governor DeSantis, passed after the Parkland trial in which a jury could not unanimously recommend death for Nikolas Cruz, a death recommendation now required only eight votes out of 12, rather than a unanimous decision. The prosecution had four aggravating factors. The defense had 42 mitigating circumstances. Zieler went back to his cell and waited.
The penalty phase began on May 23rd, 2023. The same jury that had convicted Zieler reconvened to decide between death and life in prison. The final decision would rest with Judge Robert Branning, but the jury’s recommendation carried enormous weight. Jan Cornell took the stand again. This time she was not describing the crime scene. She was describing what the 33 years after it had been like. “We’ve lived in fear,” she told the jury. “We have lived in sadness. We miss them both.”
Randy Richards followed her. He described Lisa as outgoing, loyal, and deeply proud of her work. He talked about her parents, how her death had broken them visibly, how her mother deteriorated year by year in the aftermath. He said losing Lisa had not been a single moment of grief. It had been a continuous condition across three decades.
The prosecution then laid out their four aggravating factors. Zieler had prior convictions for violent felonies. The murders were committed during a burglary. The murders were cold, calculated, and premeditated. And the murders were especially heinous, atrocious, and cruel. Each factor was grounded in the specific facts of what happened inside that apartment.
The defense presented their mitigation. Attorney Kevin Shirley told the jury this was the most difficult decision they would ever make. He pointed to two circumstances in particular. Zieler had been fighting HIV and AIDS for 7 years, and he had suffered serious childhood abuse. Dr. Julie Harper, a forensic psychiatrist, testified about Zieler’s background. His father was physically abusive. His mother showed no warmth. He grew up frightened every day. Harper diagnosed him with major depressive disorder and mild neurocognitive disorder. She said his inability to stop talking when the judge told him to was not defiance. It was a neurological limitation called poor conceptual shifting. A neurologist added that Zieler also had Parkinsonism, a degenerative condition that does not respond to standard treatment. The defense submitted all 42 mitigating circumstances for the jury to weigh.
Closing arguments in the penalty phase carried a different weight than those in the guilt phase. The guilt phase asked whether Zieler did it. The penalty phase asked what he deserved for doing it. Prosecutor Daniel Feinberg placed photographs of Robin and Lisa before the jury and walked through each aggravating factor. He ended the same way he had ended the guilt phase closing, asking the jury to hold in their minds the 60 to 70 seconds before Robin Cornell lost consciousness. He said nothing more and sat down.
Defense attorney Kevin Shirley argued with genuine emotion that the 42 mitigating circumstances deserved real weight. He asked the jury to consider whether the crime truly met the legal definition of cold, calculated, and premeditated. He reminded them that a death sentence could not be undone. Zieler declined to testify. He sat and listened.
The jury deliberated for 5 hours. They came back 10 to 2 in favor of death. All 12 jurors unanimously agreed that all four aggravating factors had been proven beyond a reasonable doubt. 10 of the 12 decided those factors outweighed everything the defense had presented. Judge Branning scheduled a Spencer hearing for June 26th, 2023, the final proceeding before he would impose the official sentence. Defense attorneys signaled they would use it to file a motion for a new trial and argue that the conviction should be overturned. Jan Cornell and Randy Richards went home and waited.
On the morning of June 26th, 2023, Joseph Zieler arrived at the Lee County Courthouse in Fort Myers in shackles. The Spencer hearing was scheduled, a proceeding that would give him and his attorneys the opportunity to present arguments to Judge Branning before the final sentence was announced. Before the hearing formally began, defense attorneys filed a motion for a new trial. They argued that Zieler had received ineffective assistance of counsel, that the jury had been biased, and that the judge’s conduct during the trial had been prejudiced against the defense. These were serious legal arguments, each one capable, if successful, of unwinding everything that had come before.
Judge Branning heard the arguments. He considered the motion carefully. Then, chaos entered the courtroom. Zieler, sitting at the defense table, motioned to his attorney, Kevin Shirley. He waved him over with what appeared to be urgency. The gesture of a man who needed to say something privately, something he did not want picked up by the microphones. Shirley walked over and bent down, leaning in to hear what his client was going to say. Zieler raised his elbow and struck Shirley across the side of the head.
Two bailiffs immediately tackled Zieler to the floor. They held him there, restrained him, and removed him from the courtroom. The gallery watched. The judge watched. Kevin Shirley stood up and straightened himself. He turned to the judge and told him he was fine. He was a former boxer, he said. He had taken better shots than that. Shirley spoke to reporters after the incident. He said Zieler had waved him down in a way that appeared to be a request for a private conversation, that the gesture was designed to draw him close enough for the strike to land. He said he did not know why his client had done it.
Zieler was escorted back into the courtroom approximately 10 minutes later. He had one more thing he wanted to say. He refused to allow any of his family members to speak on his behalf in the proceeding. Then, he addressed the court directly. “I have nothing to do with this,” he said. “I maintain my innocence.”
Judge Branning denied the motion for a new trial. He declined to overturn the conviction. He proceeded to the sentencing. Judge Branning looked at Zieler and read the sentence aloud. He stated that the aggravating factors in the case far outweighed the mitigating circumstances presented by the defense. He addressed the nature of what had happened in that apartment on the night of May 9th, 1990. The deliberate entry, the attacks on two people who had no warning, no means of escape, and no connection to anything Zieler could justify. He addressed the fact that Joseph Zieler had spent 33 years living in the same community where this crime had occurred, with full knowledge of what he had done.
“The court concludes that under the laws of the state of Florida,” Judge Branning said, “the defendant has forfeited his right to live.” He sentenced Zieler to death on count one, the murder of Lisa Story. He sentenced Zieler to death on count two, the murder of Robin Cornell. He sentenced him to life in prison for each of the two sexual battery counts. He sentenced him to 15 years for the burglary charge. Two death sentences, two life sentences, 15 years on top.
Outside the Lee County Courthouse, Jan Cornell spoke the words she had been carrying for 33 years. “Nothing can take the place of hearing the words today that justice for Robin and justice for Lisa has happened. He will never see a free moment. He will never hurt another individual on this earth. For that, I could not be more grateful.” She thanked the Cape Coral Police Department, the prosecutors, and everyone who had worked the case across multiple decades. Then, she said what she had needed to say since 1990. “They were here. They lived. Some evil monster cut their lives so short, so unfair. But now they have peace, and now we can let them have peace.”
Zieler was transported to Florida State Prison in Raiford and placed on death row. He was 61 years old, carrying two death sentences and concurrent life terms. His attorney immediately announced an appeal. In August 2023, he was formally processed onto Florida’s death row, where his case entered the automatic appeals process that begins with a direct appeal to the Florida Supreme Court.
Florida’s death row housed one of the largest condemned populations in the United States. As of Zieler’s arrival in 2023, the state had several hundred inmates awaiting execution, the result of decades of capital sentences that had accumulated across a legal system with lengthy appeals processes and relatively infrequent execution dates. Zieler arrived with two specific and significant legal questions following him. His defense team at the appellate level, new attorneys separate from the trial team, identified the issues most likely to generate appellate review. They were precise and procedural, the kind of arguments that capital appeals are typically built around, not claims of innocence, but claims that the process by which the outcome was reached was flawed in ways that the law required to be corrected.
The first issue was the jury selection error from February 2023. That first jury panel had been told, incorrectly, that a life sentence would not include parole eligibility. At the time of the murders in 1990, parole was a legal option in Florida. Telling a jury that parole was impossible when it was not was a factual error with potential implications for how those jurors understood the full weight of the sentencing decision they were being asked to make. The panel had been dismissed and a new one seated, but the appellate team argued that the episode tainted the overall process.
The second issue was the application of the April 2023 sentencing law. Zieler’s trial had formally begun in February 2023 with jury selection. The new law reducing the death recommendation threshold from unanimous to eight votes was signed in April 2023 after that initial process had started. Zieler received a 10 to 2 recommendation under the new threshold. His attorneys argued that applying a law passed after his trial began to his sentencing process was a constitutional violation, that the law effective at the time his trial commenced should have governed his sentencing, and that under the previous requirement, the 10 to 2 vote would not have been sufficient to recommend death.
The third issue the appellate team raised was the DNA evidence itself. Specifically, the handling of the evidence over 26 years, and the defense’s contention that material had been improperly managed or altered.
On October 9th, 2023, the trial court submitted the full record to the Florida Supreme Court. The court issued a briefing schedule two days later. Zieler’s case became the first direct appeal to reach the Florida Supreme Court under the 2023 capital sentencing statute. The first case in which the court would be asked to rule on whether that statute applied to trials that had begun before its passage. This made the Zieler case something beyond a single man’s appeal. It was a legal question with implications for every capital case in Florida that had been prosecuted under similar circumstances.
The briefing proceeded over the following months. Written arguments were submitted by Zieler’s appellate attorneys and by the state’s legal team. The Florida Supreme Court read the briefs, reviewed the record, and scheduled oral arguments. On January 9th, 2025, it was announced that oral arguments in Joseph Zieler v. State of Florida were scheduled for February 5th, 2025. Jan Cornell’s name was not in that case caption. She was not a party to the appeal. But she knew what it meant, and she had known since the day in June 2023 when Kevin Shirley announced the appeal was coming. Jan Cornell had spent 33 years waiting for justice. She was prepared to wait through whatever came next.
On February 5th, 2025, seven Florida Supreme Court justices heard oral arguments in Joseph Zieler v. State of Florida in Tallahassee. Zieler was not present. His attorney, Steven Beloten, made one central argument. The law in effect when a trial begins should be the law that governs it. Zieler’s trial began in February 2023. The new sentencing law lowering the death recommendation threshold was signed in April 2023. Under the law that existed when his trial started, a death recommendation required a unanimous jury vote. His jury was not unanimous. Therefore, Beloten argued, the death recommendation should not stand. He also challenged the DNA chain of custody and the weighing of aggravating versus mitigating factors.
Christina Pacheco argued for the state. She told the justices nothing had been done wrong. The DNA was properly handled, the trial was properly conducted, and the sentencing law applied at the time of sentencing, not at the time jury selection began. She asked the court to affirm both convictions and both death sentences.
The court issued no ruling from the bench. No execution date had been set. Florida does not schedule executions while a direct appeal is pending. Zieler stayed on death row, 62 years old, his health continuing to decline, waiting. Florida carries out executions regularly. Florida does not let death sentences sit forever. The state has one of the most active execution schedules in the country. Men who sat on that same row—Gary Ray Bowles executed in 2019, Wade Wilson whose execution was carried out in 2024—went through the same appeals process Zieler is now inside. They argued. The courts ruled. The dates were set.
Unless the Supreme Court overturns his sentence, Joseph Zieler will almost certainly face the same end as the men who came before him on that row. A scheduled date, a final statement, and a lethal injection in the execution chamber at Florida State Prison. The system that could not find him for 26 years now has him. And it is not letting go.
