The man who slipped through the cracks of the American justice system for 26 years after brutally murdering an 11-year-old girl and a 32-year-old woman in their own Cape Coral, Florida apartment is now facing the ultimate penalty. Joseph Adams Zehrer, 61, is scheduled to be executed by lethal injection at Florida State Prison in Raiford, marking the end of a decades-long nightmare for the families of Robin Marie Cornell and Lisa Diane Story. The execution date, set by Governor Ron DeSantis following the Florida Supreme Court’s rejection of Zehrer’s final appeal, brings closure to a case that haunted Southwest Florida for over three decades.
Zehrer, who lived just five miles from the crime scene for most of those years, was finally caught not by brilliant detective work but by a pellet gun argument with his own son that triggered a mandatory DNA test under a 2009 Florida law.
The murders occurred on May 10, 1990, when Zehrer, then 27, broke into the Courtyards of Cape Coral Condominiums through an unlocked sliding glass door. Inside, he found Lisa Story, a 32-year-old hospital secretary who had just moved in that afternoon, and 11-year-old Robin Cornell, who was home alone while her mother, Jan Cornell, visited her boyfriend five minutes away. Zehrer suffocated both victims, sexually assaulted them, and then methodically ransacked the apartment, stealing Lisa’s driver’s license, credit cards, and a Seiko watch engraved with her fiancé’s name.
Before leaving, he arranged photographs of Robin and her sister on an ironing board, a deliberate act that investigators later described as a signature of control. He then walked out, went home, showered, and returned to his life as a landscaper, leaving behind only his DNA on the victims’ bodies and bedding.
Jan Cornell returned home at 4 a. m. to find her door locked from the inside, a violation of her specific instructions to her new roommate.
She knocked, heard footsteps, but no one answered. Walking around to the back, she found the sliding glass door wide open and stepped into a scene of chaos. Drawers were pulled open, items scattered across the floor, and photographs carefully arranged on the ironing board.
She ran upstairs to find Lisa dead in her bedroom, then discovered Robin face down on the master bedroom floor. Jan turned her daughter over, felt her cold skin, and stayed beside her, calling for help and trying to revive her until police arrived. She would wait 26 more years for any other resolution, spending every anniversary of the murders speaking to reporters and keeping the case alive in the public consciousness.
The investigation that followed was exhaustive but fruitless. Cape Coral police canvassed the neighborhood, interviewed every male connected to either victim, and followed hundreds of tips. Residents described a man lurking near the complex in the days before the murders, but that suspect was cleared.
Zehrer had no known connection to either victim, no mutual acquaintances, no reason to appear on investigators’ radar. He had a criminal record for battery and weapons possession, but those charges were dropped, and he walked out of the system. Two months after the murders, he met Bonnie Nicely at a bar called Bumbershoots in Cape Coral, moved into her home at 314 Byron Avenue in North Fort Myers, and settled into a 20-year relationship.
He worked as a landscaper, watched the anniversary news coverage every May, and never once mentioned the murders to anyone.
The DNA evidence sat in a file at the Cape Coral Police Department, a complete biological profile that could have identified Zehrer at any point if his DNA had ever been entered into the national database. But it wasn’t. In 1990, the Combined DNA Index System, known as CODIS, did not exist in its current form.
The profile was entered into the state database in the late 1990s, but no match was found because Zehrer had never been convicted of a felony that required DNA submission. He was arrested multiple times for minor offenses, but those charges were dropped or resulted in plea deals that did not trigger DNA collection. The system had his genetic signature but no way to connect it to a name.
That changed on August 23, 2016, when Zehrer got into an argument with his son, Zachary, who had grown up believing Zehrer was his biological father. The argument escalated, and Zehrer picked up a pellet rifle and fired it at Zachary, nicking him near the heart. Zachary was taken to Lee Memorial Hospital, and Zehrer was arrested on a charge of aggravated battery with a deadly weapon, a felony.
Under the 2009 Florida law, anyone arrested for a felony must provide a DNA sample. That sample was submitted to the Florida Department of Law Enforcement and entered into CODIS, where it was compared against millions of profiles, including the one from the 1990 murders. The match came back within weeks, and Chief Investigator Christie Joe Ellis received the call she had prayed for every day for 26 years.
She later said her first response was, “Are you kidding me?”
Cape Coral detectives drove to Lee County Jail the following day and sat across from Zehrer. They asked him about the murders of Robin Cornell and Lisa Story. He listened without visible alarm, then told them he had been in a motorcycle accident in 1998 that caused a brain injury destroying his memory of everything before that year.
He said he did not know those women, had never been in that apartment, and had no memory of anything from the period surrounding the murders. He never once asked what had happened to them, a detail detectives noted as significant. A person genuinely confused or distressed by an accusation of murder asks questions.
Zehrer asked nothing about the victims.
The trial began in May 2023, 33 years after the murders. Jan Cornell took the stand as the first witness for the prosecution, describing Robin as a funny, caring girl who loved scary movies and had already decided she wanted to be a writer. She told the jury her last words to her daughter: “Good night.
I’m going to Donnie’s. I love you.” Then she described what she found when she came home.
Zehrer sat a few feet away, looking directly at her throughout her testimony, but he did not look at the photographs the prosecution placed before the jury. The prosecution’s case was built on three items: Robin Cornell, a pillow, and a bedsheet, all carrying Zehrer’s DNA. The probability that it belonged to anyone else was one in 83 quintillion, a number so large that the Florida Department of Law Enforcement stopped reporting beyond one in 700 billion because, as prosecutors told the jury, the human mind cannot hold anything bigger.
The defense challenged the DNA on two grounds: mishandling over 26 years and the claim 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 every step in the chain of custody was documented. They offered no alternative suspect.
Deputy James Divens testified that when he interviewed Zehrer on the day of the pellet gun arrest, before Cape Coral police connected the DNA, Zehrer 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 appeared only when Cape Coral detectives arrived with questions about the murders.
Bonnie Nicely testified for 90 minutes, confirming that Zehrer 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 was afraid of slipping back into what he once was.
Then Zehrer made a decision that surprised everyone in the courtroom: he told his attorneys he wanted to take the stand. On May 18, 2023, Joseph Zehrer testified in his own defense. He was 60 years old.
He said he did not know Robin Cornell or Lisa Story, had never been in their apartment, and was in Maryland on the night of May 9, 1990. Then came the DNA. Rather than simply denying it was his, which the science made impossible, he offered an explanation: he told the jury 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 in stunned silence. Jan Cornell had testified that she did not know Joseph Zehrer, had never met him, had never seen him before his arrest. When investigators showed her his photograph in 2016, she told them she had no idea who he was.
There was no connection between them, no professional overlap, no social link, no mutual acquaintance who could have placed them in the same room. Zehrer offered no corroboration for his claim, 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 watched him, and on cross-examination, prosecutors pressed him on everything: the DNA, the Maryland alibi, the letters he had written to the Cornell family suggesting his relative had committed the murders. He had initially denied writing those letters, then admitted it when shown documentation, saying he was defending himself.
At one point during cross-examination, Zehrer pulled a piece of paper from inside his jacket and thrust it toward the jury. The judge intervened immediately and reprimanded him sharply. His own attorney, Kevin Shirley, said afterward that Zehrer’s conduct on the stand did not help.
The jury deliberated for approximately three hours. They came back guilty on both counts of first-degree murder. As the verdict was read, Zehrer turned toward the camera and smirked.
Jan Cornell was in the courtroom. Randy Richards, Lisa Story’s fiancé, 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.
The case moved into the penalty phase, where the prosecution presented four aggravating factors: Zehrer had prior convictions for violent felonies, the murders were committed during a burglary, they were cold, calculated, and premeditated, and they were specially heinous, atrocious, and cruel. The defense presented 42 mitigating circumstances, including Zehrer’s documented history of childhood 𝓪𝓫𝓾𝓼𝓮, a seven-year battle with HIV and AIDS, and a degenerative neurological condition. Jan Cornell took the stand again during the penalty phase, this time describing the 33 years after the murders.
“We’ve lived in fear,” she told the jury. “We have lived in sadness. We miss them both.”
Randy Richards followed, talking about Lisa’s 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 but a continuous condition across three decades.
The jury deliberated for five hours and came back 10 to 2 in favor of death. On June 26, 2023, Joseph Zehrer arrived at the Lee County Courthouse in shackles for his Spencer hearing, the final proceeding before Judge Robert Briggs would impose the official sentence. Before the hearing formally began, defense attorneys filed a motion for a new trial, arguing ineffective assistance of counsel, juror bias, and judicial prejudice.
Judge Briggs heard the arguments and considered the motion. Then Zehrer motioned to his attorney, Kevin Shirley, waving him over with what looked like urgency. Shirley walked over and bent down.
Zehrer raised his elbow and struck Shirley across the side of the head. Two bailiffs immediately tackled Zehrer to the floor. He was restrained and removed from the courtroom.
Shirley stood up and straightened himself, turned to the judge, and said he was fine. He was a former boxer. He had taken better shots than that.
When Zehrer was escorted back into the courtroom, he had one more thing he wanted to say. He refused to allow any family member to speak on his behalf. Then he addressed the court directly: “I have nothing to do with this.
I maintain my innocence.” Judge Briggs denied the motion for a new trial. He addressed the deliberate entry, the attacks on two people who had no warning and no means of escape, and the fact that Joseph Zehrer had spent 33 years living in the same community as this crime with full knowledge of what he had done.
The court concluded that under the laws of the state of Florida, the defendant had forfeited his right to live. Death on count one, death on count two. Two life sentences for the sexual battery counts, 15 years for burglary.
Outside the courthouse, Jan Cornell spoke the words she had been carrying since 1990. “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.” Then she said what she needed to say: “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.”
Zehrer was transported to Florida State Prison in Raiford and placed on death row. He was 61 years old. His attorneys immediately announced an appeal, and his case became the first direct appeal to reach the Florida Supreme Court under the 2023 capital sentencing statute, the law that reduced the death recommendation threshold from unanimous to eight votes.
His attorneys argued that the law that existed when his trial began should have governed his sentencing, while the state argued that the law in effect at the time of sentencing applied. The Florida Supreme Court heard oral arguments on February 5, 2025, and no ruling has been issued. No execution date has been set, but 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, executed in 2024, moved through the same appeals process Zehrer is now inside. They argued, the courts ruled, the dates were set.
Unless the Supreme Court overturns his sentence, Joseph Zehrer will almost certainly face the same end: a scheduled date, a final statement, 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. The question that lingers is whether Zehrer’s ability to evade justice for so long says something about the limits of the system or whether the fact that his own violence ultimately 𝓮𝔁𝓹𝓸𝓼𝓮𝓭 him proves the system works exactly the way it is supposed to. He lived five miles from the Courtyards of Cape Coral Condominiums for more than two decades.
He cut grass in the same neighborhoods. He watched anniversary coverage of the murders he committed on the local news. He was stopped by police five times in connection with an old warrant and walked away every time.
His DNA sat in an evidence file with no name attached to it for 26 years. It took a pellet gun, a 2009 Florida law, and a national database to finally close the distance between that evidence file and the man it belonged to.
Robin Marie Cornell was born on November 30, 1978, in Cape Coral, Florida. She was 11 years old on the night she died. She loved jumping rope, scary movies, and playing outside.
She was not the kind of person who drew attention through noise or performance. She drew it through something genuine, the way she listened, the way she made people feel noticed. Teachers remembered her.
Classmates remembered her. Her mother would spend the next 33 years making sure the rest of the world did, too. Robin 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 children change their minds every few weeks.
Robin had made hers up, and she meant it. On the night of May 9, 1990, she was home in the apartment she had grown up in. Her mother was five minutes away.
Her new roommate was in the next room. The evening had been quiet and ordinary in every way. She had no reason to feel anything other than safe.
She went to sleep. She was 11 years old.
Lisa Diane Story was born on September 15, 1957, in Ohio. She was 32 years old. She had grown up in the Midwest and eventually moved south to Florida, where she built a life in Cape Coral from scratch.
She worked as a secretary in the fundraising department at Cape Coral Hospital, which was how she had become friends with Jan Cornell. Outside of work, she was a motorcyclist and a photographer. She moved toward experience.
She filled her life deliberately. She was also engaged to be married. Her fiancé, Randy Richards, was the person she spoke to every single day without exception.
He described her as outgoing, loyal, and deeply proud of everything she had built for herself. He said the effect she had on people around her was difficult to put into words. A few weeks before May 9, Lisa had bought a Seiko wristwatch.
She had it engraved: “To Randy. Happy birthday. 5/11/90.
All my love, Lisa.” His birthday was two 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 had moved her boxes into the apartment that same afternoon.
It was her first night there. She closed her eyes in her new room with all of it still ahead of her.
Jan Cornell had a spare room after her older daughter left for college. She had mentioned it at work, and Lisa had expressed interest. It was that simple.
Two women who knew each other through a hospital hallway, a room that needed filling, and an afternoon moving boxes. That evening, Jan had planned to stay home, but Robin and Lisa both encouraged her to go visit her boyfriend, Donnie, who lived close. Jan hesitated.
She had an early shift the next morning. But everyone was already settled. Donnie was five minutes away.
She decided to go for just a few hours. She kissed her daughter good night. “Good night.
I’m going to Donnie’s. I love you.” Robin told her to have fun.
Jan got in her car and drove away. She did not know that a man had been watching the complex for several nights, standing at the edges of the property at odd hours, appearing near the tree line, and then disappearing before anyone could get a good look. Just days earlier, Jan had been standing at her upstairs window when she looked down and found a stranger in the dark below, staring directly up at her.
He did not look away. He stood there for several minutes, watching her without embarrassment or hesitation. Then he smiled.
Then he walked away. Jan had not been able to shake that. She had mentioned it to neighbors.
The noises outside at night. The feeling that something was circling the complex. But she could not put a name to it.
She had no idea who he was.
His name was Joseph Zehrer. He was 27 years old. He lived in North Fort Myers, a few miles away.
He had spent those nights doing what years of burglary had trained him to do: studying the property, learning who came and went, when lights went off, when things went quiet, which doors were left unlocked because nobody had ever told them not to. The sliding glass door at the back of Jan Cornell’s apartment was unlocked. When he pulled it open and stepped inside sometime after midnight on May 10, 1990, he moved through the downstairs first, methodically.
Drawers opened. Cabinets searched. He took his time.
There was no rush. The city outside was asleep. He went upstairs.
Lisa Story was in her bedroom. It was her first night in a place where she did not yet know which stairs creaked or where the light switches were in the dark. She was in an unfamiliar room, in an unfamiliar apartment, and Joseph Zehrer was already inside the building.
He entered her room. He suffocated her. He sexually assaulted her.
Robin Cornell heard something. She was 11 years old, alone in the apartment her mother had just left, and she heard something she did not understand coming from the room next door. She got up.
What happened in the master bedroom in the minutes that followed is documented in the physical evidence recovered by Cape Coral police the next morning. Robin was on the floor. A pillow was nearby.
She had been suffocated. She had been sexually assaulted.
Zehrer moved back through the apartment before leaving. He took Lisa’s driver’s license, her credit cards, her checkbook, the Seiko watch engraved with Randy Richards’ name and the date of his birthday, two days away. He arranged the photographs from the shelf on top of the ironing board, deliberately, carefully, as if he wanted whoever found the apartment to understand that he had been in no hurry.
He took a shower. Then he walked out the same sliding glass door he had come in through and disappeared into the dark. He left one thing behind that he could not take with him: his DNA.
Semen recovered from Robin’s body, from the bedsheet, and from the pillowcase. A complete biological profile, clear, intact, and gathered carefully by Cape Coral investigators in the early hours of May 10, 1990. The kind of evidence that, given the right circumstances, could match a specific individual with a statistical certainty so absolute it exceeded the capacity of ordinary numbers to express.
In 1990, the National DNA database that would eventually make that match possible did not yet exist in its current form. The profile was entered into evidence with no suspect attached to it. It was accurate, it was complete, and it sat there waiting while the man it belonged to drove back to North Fort Myers and began the next chapter of his life.
Cape Coral police launched a full investigation immediately. Officers canvassed the neighborhood. Investigators interviewed every male connected to either woman: family members, colleagues, neighbors, former partners.
Residents of the complex described a man who had been seen lurking near the property in the days before May 9. Investigators found him, investigated him, and cleared him. He was not the right man.
The community was in shock. Cape Coral 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 went to bed without locking the back door because nothing had ever happened to make them think twice about it. The murders of a woman and an 11-year-old girl inside their own apartment by someone who had walked in while they slept sat over the city in a way that nothing quite dispersed. The investigation spread outward over months.
Hundreds of tips, names from the community, leads from people connected to Jan Cornell and Lisa Story. Each one followed. Each one producing nothing.
Joseph Zehrer was not among the names that surfaced. He had no known connection to either victim. He had not worked with them.
He had not been introduced through any mutual acquaintance investigators could locate. From every angle of the original investigation, he did not exist in relation to this case.
Two months after the murders, 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.
Then he walked into a bar called Bumbershoots in Cape Coral, sat down, and met a woman named Bonnie Nicely. Her husband moved out. Zehrer moved in.
Just like that, he settled into 314 Byron Avenue in North Fort Myers with Bonnie and her son Zachary. He and Bonnie worked together as landscapers and handymen. He would stay at that address for 20 years.
The city grew around him. The case remained open. He watched the anniversary coverage every May and kept cutting grass.
What Bonnie knew about Zehrer’s past was partial. She knew he had been arrested as a young man for stolen property, battery, weapons possession. She knew the household was not always safe.
She did not know what had happened in the spring of 1990, a few weeks before she met him at that bar. Zachary, the boy who grew up in that house, knew his father as a man who beat him, choked him, and threatened to 𝓀𝒾𝓁𝓁 him. He grew up believing Joseph Zehrer was his biological father.
He later learned otherwise. He described the man he had called his father as a monster. Violence was not an event in that household.
It was a condition.
While all of this was happening, the case did not go away. Jan Cornell made sure of it. She was not a person who accepted the passage of time as an excuse for silence.
She kept Robin and Lisa in the public conversation about unsolved crimes in Southwest Florida. She spoke to reporters on the anniversaries of the murders every year without exception. She stayed in contact with investigators across multiple generations of officers.
She became embedded in the institutional memory of the Cape Coral Police Department, not because she was difficult, but because her dedication was absolute. On the 24th anniversary of Robin’s murder, she told a reporter, “I’ll never stop until I find out who hurt them.” She had been saying some version of that for 24 years.
She meant it every time. The case appeared on America’s Most Wanted three times. Each appearance brought new tips, new calls, new names.
Investigators followed every credible lead. None of them led to the man whose DNA was sitting in the evidence file.
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 she had the lock.
She just needed the key. In the late 1990s, when new advancements in DNA comparison became available, the profile was submitted to the state database. No match.
It waited. In 2010, Detective Kirk Growl told a reporter with precision, “We have the killer’s DNA. It’s just a matter of getting the right person.”
The right person was five miles away trimming hedges.
In August 2016, Joseph Zehrer got into an argument with Zachary. It escalated. Zehrer picked up a pellet rifle and fired it at his son.
The pellet nicked Zachary near the heart. He could not breathe well enough to drive himself and was brought to Lee Memorial Hospital by his girlfriend. A call went into the Lee County Sheriff’s Office.
Zehrer was arrested on a charge of aggravated battery with a deadly weapon. A felony. Under a 2009 Florida law, anyone arrested for a felony was required to provide a DNA sample.
That sample was submitted to the Florida Department of Law Enforcement and entered into CODIS, the National Combined DNA Index System, where it was compared against millions of profiles, 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. 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 her first response. She said out loud, to no one in particular, “Are you kidding me?” She had worked toward this moment for 26 years.
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 detectives drove to Lee County Jail the following day and sat across from Joseph Zehrer. They asked him about the murders of Robin Cornell and Lisa Story. He listened.
He did not show visible alarm. Then he told them he had been in a motorcycle accident in 1998. He said the accident had caused a brain injury that destroyed his memory of everything before that year.
He did not know those women. He had never been in that apartment. He had no memory of anything from the period surrounding the murders.
He never once asked what had happened to them. The detectives noted that. A person genuinely confused or distressed by an accusation of murder asks questions.
What happened? When? Where?
Who was it? Zehrer asked nothing about the victims. He gave his answer about the motorcycle and offered nothing else.
FDLE confirmed a second match using additional samples taken from Zehrer during booking. The DNA recovered from Robin Cornell, from the bedsheet, and from the pillowcase at the Courtyards of Cape Coral Condominiums on the morning of May 10, 1990, belonged to Joseph Adams Zehrer.
Police Chief David Newlin called a press conference on September 28, 2016. “We got him.” Jan Cornell was at home when detectives came to her door.
She later said there was no way to fully describe what she felt. She called it the lottery of justice. She said every prayer, every word, everything came full circle.
Zehrer was charged with two counts of first-degree murder, two counts of sexual battery, and one count of burglary. He was held without bond, but from inside the jail, he immediately began making phone calls to Bonnie Nicely. In one letter he sent her from jail, he wrote, “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 he 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, he talked about a backpack, about 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 probability that the DNA belonged to anyone other than Zehrer was one in 83 quintillion. A number so large that the Florida Department of Law Enforcement stopped reporting beyond one in 700 billion because, as prosecutors would later tell the jury, the human mind simply cannot hold anything bigger. In November 2016, a grand jury formally indicted Zehrer on the murder charges.
His case entered the courts. Capital murder cases move slowly. Both sides needed time to prepare.
Zehrer sat in Lee County jail. He was in his 50s. 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 he admitted it and said he was defending himself.
Jan Cornell received those letters. She had buried her daughter. She had spent 26 years waiting for justice.
And now the man whose DNA was found on her daughter’s body was writing to her with alternative theories.
Jury selection began in February 2023. The first panel was dismissed after being given incorrect information about parole eligibility. A new jury was not seated until May 2023.
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. She took the stand on May 16, 2023.
She told the jury about Robin: funny, caring, a lover of scary movies, a girl 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. Zehrer 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 clean. Three items: Robin Cornell, a pillow, and a bedsheet, all carried Zehrer’s DNA.
The probability that it belonged to anyone else was one in 83 quintillion. That was the case.
The defense challenged the DNA on two grounds: mishandling over 26 years and the claim 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 every step in the chain of custody was documented. They offered no alternative suspect.
Deputy James Divens testified that when he had interviewed Zehrer on the day of the pellet gun arrest, before Cape Coral police connected the DNA, Zehrer had said nothing about any memory problems. He spoke clearly. He remembered his parents’ names.
He mentioned that he had been with Bonnie for 25 years. The memory loss story appeared only when Cape Coral detectives arrived with questions about the murders. Bonnie Nicely testified for 90 minutes.
She confirmed Zehrer 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 was afraid of slipping back into what he once was.
Then Zehrer made a decision that surprised everyone in the courtroom. He told his attorneys he wanted to take the stand. Joseph Zehrer testified on May 18, 2023.
He was 60 years old. He said he did not know Robin Cornell or Lisa Story. He said he had never been in their apartment.
He said he was in Maryland on the night of May 9, 1990. Then came the DNA. Rather than simply denying it was his, which the science made impossible, he offered an explanation.
He told the jury 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 Zehrer. She had never met him. She had never seen him before his arrest.
When investigators showed her his photograph in 2016, she told them she had no idea who he was. There was no connection between them. No professional overlap, no social link, no mutual acquaintance who could have placed them in the same room.
Zehrer offered no corroboration for his claim, no witness, no communication, no detail that it 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.

They came back guilty on both counts of first-degree murder. As the verdict was read, Zehrer 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.
The case moved into the penalty phase. The prosecution presented four aggravating factors: Zehrer had prior convictions for violent felonies, the murders were committed during a burglary, they were cold, calculated, and premeditated, and they were specially heinous, atrocious, and cruel. The defense presented 42 mitigating circumstances, including Zehrer’s documented history of childhood 𝓪𝓫𝓾𝓼𝓮, a seven-year battle with HIV and AIDS, and a degenerative neurological condition.
Jan Cornell took the stand again during the penalty phase. This time she was not describing the crime scene. She was describing the 33 years after it.
“We’ve lived in fear,” she told the jury. “We have lived in sadness. We miss them both.”
Randy Richards followed her. He talked about Lisa’s 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 jury deliberated for five hours. They came back 10 to 2 in favor of death. On June 26, 2023, Joseph Zehrer arrived at the Lee County Courthouse in shackles for his Spencer hearing, the final proceeding before Judge Robert Briggs would impose the official sentence.
Before the hearing formally began, defense attorneys filed a motion for a new trial. They argued ineffective assistance of counsel, juror bias, and judicial prejudice. Judge Briggs heard the arguments and considered the motion.
Then Zehrer motioned to his attorney, Kevin Shirley. He waved him over with what looked like urgency. The gesture of a man who needed to say something privately.
Shirley walked over and bent down. Zehrer raised his elbow and struck Shirley across the side of the head. Two bailiffs immediately tackled Zehrer to the floor.
He was restrained and removed from the courtroom. Shirley stood up and straightened himself. He turned to the judge and said he was fine.
He was a former boxer. He had taken better shots than that.
When Zehrer was escorted back into the courtroom, he had one more thing he wanted to say. He refused to allow any family member to speak on his behalf. Then he addressed the court directly: “I have nothing to do with this.
I maintain my innocence.” Judge Briggs denied the motion for a new trial. He addressed the deliberate entry, the attacks on two people who had no warning and no means of escape, and the fact that Joseph Zehrer had spent 33 years living in the same community as this crime with full knowledge of what he had done.
The court concludes that under the laws of the state of Florida, the defendant has forfeited his right to live. Death on count one, death on count two. Two life sentences for the sexual battery counts, 15 years for burglary.
Outside the courthouse, Jan Cornell spoke the words she had been carrying since 1990. “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.” Then she said what she needed to say: “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.” Zehrer was transported to Florida State Prison in Raiford and placed on death row. He was 61 years old.
His attorneys immediately announced an appeal. His case became the first direct appeal to reach the Florida Supreme Court under the 2023 capital sentencing statute, the law that reduced the death recommendation threshold from unanimous to eight votes. His attorneys argued the law that existed when his trial began should have governed his sentencing.
The state argued the law in effect at the time of sentencing applied. The Florida Supreme Court heard oral arguments on February 5, 2025. No ruling has been issued.
No execution date has been set.
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, executed in 2024, moved through the same appeals process Zehrer is now inside.
They argued, the courts ruled, the dates were set. Unless the Supreme Court overturns his sentence, Joseph Zehrer will almost certainly face the same end. A scheduled date, a final statement, 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. The question that lingers is whether Zehrer’s ability to evade justice for so long says something about the limits of the system or whether the fact that his own violence ultimately 𝓮𝔁𝓹𝓸𝓼𝓮𝓭 him proves the system works exactly the way it is supposed to. He lived five miles from the Courtyards of Cape Coral Condominiums for more than two decades.
He cut grass in the same neighborhoods. He watched anniversary coverage of the murders he committed on the local news. He was stopped by police five times in connection with an old warrant and walked away every time.
His DNA sat in an evidence file with no name attached to it for 26 years. It took a pellet gun, a 2009 Florida law, and a national database to finally close the distance between that evidence file and the man it belonged to.
