It was supposed to be an ordinary day. After leaving the gym, Dan Markel drove home to Tallahassee, Florida, expecting nothing more than the usual rhythm of work, fatherhood, and the quiet routines of a summer morning. He was on the phone with a music teacher, Stewart Schlazer, talking about school options for his young children, when the conversation suddenly shifted into something terrifying. “Can you please hold on a second? There’s an unfamiliar person in my driveway,” Markel said. Seconds later, Schlazer heard what he described as “a loud boom.” That boom was the sound of a gunshot that would end the life of the 41-year-old Florida State University law professor. Markel was shot in the head while sitting in his car in the garage of his own home on July 18, 2014, and he died the following day. There is something hauntingly ordinary about those final moments, a fact that producer Lily Fletcher says stayed with her while making the new ABC News Studios docuseries, “Welcome to the Family: The Murder of Dan Markel,” now streaming on Hulu. “There are really eerie parts of those final hours,” Fletcher told Fox News Digital. “You look at the CCTV footage, and it’s a normal day. Dan dropped off the kids at school, he’s gone to work out at the gym, and then there’s a Prius driving around the gym car park. It never stops. It’s clearly waiting for him.” She described the sight as “a shark circling” — something sinister hiding in plain sight during a mundane part of his day. The chilling reality is that while Markel went about his ordinary morning, his killer was already watching, waiting for the perfect moment to strike.
Dan Markel was far more than a headline. He was a prominent legal scholar, a devoted father to two young sons, and a man whose life was torn apart by a bitter divorce and a custody dispute that spiraled into a nightmare no one could have predicted. Markel married Wendi Adelson in 2006 after the two met online, and together they built a life that seemed, from the outside, to be full of promise. They had two sons, Benjamin and Lincoln, and Markel was thriving in his career as a law professor. But the marriage eventually fell apart, and their 2013 divorce became a bitter battle centered on one agonizing question: where would their boys grow up? Wendi wanted to move to South Florida to be near her family, while Markel fought to keep the children in Tallahassee, where the parents shared custody. The docuseries depicts prosecutors’ theory that Wendi’s mother, Donna Adelson, was a dominating, controlling force in the family, a woman with strong opinions about her daughter’s choices and a fiery resentment toward the ex-son-in-law she reportedly “hated.” According to the documentary, Donna was furious when the relocation request was denied. The custody dispute, prosecutors argued, became the catalyst for a murder-for-hire plot that would take years to unravel. At the heart of it all was a broken family, two little boys who lost their father, and a mother and brother who allegedly believed they could control the outcome of a legal fight by eliminating the man who stood in their way. The tragedy is not just the violence of Markel’s death, but the fact that it grew out of something so deeply personal — a family’s refusal to accept a court’s decision and their willingness to destroy a life to get what they wanted.
The murder-for-hire plot that prosecutors would eventually lay out in court was shocking in its scope and cruelty. They argued that Donna Adelson helped orchestrate Markel’s killing after he stood in the way of letting her daughter and two grandsons move south. They also revealed that her son, Charlie Adelson, arranged for the killing through his then-girlfriend, Katherine Magbanua. Magbanua, in turn, connected Charlie to Sigfredo Garcia, the father of her children, and Garcia’s childhood friend Luis Rivera. According to prosecutors, Garcia shot Markel while Rivera drove the getaway car. Over the next decade, investigators painstakingly pieced together the conspiracy using cellphone records, surveillance video, financial records, and secretly recorded conversations. It was a slow, methodical process that tested the patience of everyone involved. “Investigators suspected members of the family were involved, but weren’t able to prove it beyond a reasonable doubt for a really long time,” Fletcher said. She marveled at the thoroughness of the investigation, saying, “What really surprised me about the investigation was how incredibly thorough and how many needles in how many haystacks they went through to find the evidence, whether it was tracking silver-colored Priuses across Florida, or going through thousands of phone data to find any links to the family and near the crime scene.” The docuseries includes exclusive interviews, including with FBI agent Pat Sanford, and a recorded conversation with Rob Adelson, the oldest Adelson son, who testified against his mother at her trial. It is a story built on painstaking detective work, showing that even the most carefully planned crimes leave behind traces of the truth.
The courtroom reckoning that followed was long and dramatic. In 2023, Charlie Adelson, a dentist, was convicted of first-degree murder, conspiracy to commit murder, and solicitation to commit murder in the killing of his former brother-in-law. Prosecutors told jurors that Charlie paid to have Markel killed and used Magbanua to hire Garcia, who enlisted Rivera’s help. Charlie testified in his own defense, insisting he had nothing to do with the killing and claiming he was stunned when Magbanua came to his home and said her friends were the killers. He also said he needed to pay more than $300,000 in 48 hours or he would be killed. The jury didn’t believe him, and he was sentenced to life in prison. Magbanua and Garcia were also convicted of first-degree murder, and Rivera was sentenced to 19 years in prison after pleading guilty to second-degree murder and cooperating with prosecutors. Then, in 2025, Donna Adelson was convicted of first-degree murder, conspiracy to commit murder, and solicitation to commit murder. She was sentenced to life in prison without the possibility of parole, plus an additional 30 years for the conspiracy and solicitation convictions. At trial, prosecutors painted Donna as the calculated matriarch of an affluent South Florida family with the means and motive to orchestrate the killing of the ex-son-in-law she “hated.” Defense attorneys insisted the state didn’t have sufficient evidence to link her to the murder plot, but the jury saw it differently. For Markel’s loved ones, the convictions brought a measure of justice, but no verdict could bring back a father, a son, a brother, and a friend. The trials exposed the dark underbelly of a family that appeared successful and respectable on the surface, but was ultimately consumed by bitterness, control, and a willingness to destroy anyone who stood in their way.
What makes the story even more unsettling, according to Fletcher, is not just the crime itself, but the way the Adelson family continued to live their lives while the investigation hovered around them. The documentary team listened to hundreds of FBI wiretap recordings, and what they heard left them with a deep sense of unease. “There are hundreds of wiretapped phone calls of the Adelson family,” Fletcher said. “As a team, we listened to all of them. I think just the brazen way with which the family was continuing their lives during the investigation, really believing that they’d got away from it, was very disturbing. They really thought that they were above the law.” There is something chilling about hearing people casually discuss their daily lives, their relationships, and their plans while knowing they may have been involved in a murder. Fletcher said the conversations revealed a family that was deeply enmeshed in each other’s lives, with Donna and Charlie constantly meddling in Wendi’s personal affairs. “They weren’t used to not getting their way,” Fletcher said. “And I think that is really alarming to me, that there are people like that who believe that they can operate outside of the constraints of the law.” Two years after Markel’s murder, Donna and Charlie spent hours discussing Wendi’s boyfriend at the time and whether she should stay in the relationship. Fletcher described it as hours and hours of conversations, with Donna encouraging Charlie to speak to Wendi and make decisions for her. “Just the meddling and the way they’re speaking about Wendi and making decisions for her life, I felt that to be obviously really damning for them about their involvement in the case in terms of what the dynamics are like in their family,” she said. It is a portrait of a family so convinced of its own power that they seemed to forget that the world was listening.
Then there is Wendi Adelson, the woman at the center of the storm. She has repeatedly denied any involvement in her ex-husband’s murder and has never been charged with a crime. Yet online, she has become a figure of intense speculation and suspicion, with many true crime enthusiasts convinced that she must have known something or played a role. Fletcher, however, urges caution. “I don’t know why people online have such strong levels of certainty,” she said. “In listening to the wiretap conversations of Wendi’s mother and brother, and the way they are so accustomed to meddling in her life and deciding what is best for her, I could imagine a scenario in which she wasn’t involved in it at all. I think that the vitriol around Wendi, especially online, is sad in a way. I imagine a scenario in which Wendi’s family did this without her knowledge.” It is a haunting thought — that a mother and brother might have committed an unthinkable crime to help a woman who never asked for it, and that she has been left to live with the wreckage of their choices. The docuseries does not offer easy answers, but it paints a deeply human portrait of a tragedy that destroyed everyone it touched. Markel’s children lost their father in the most violent way imaginable. The Adelson family lost two of its members to prison, likely for the rest of their lives. And Wendi, whether guilty or innocent, will forever be linked to a murder that shattered her family and took away the father of her children. “This is the story of a breakdown of a marriage, a custody dispute, and problems that escalated and seemed so irreconcilable,” Fletcher said. “But this was an instance where things got so out of hand, and no one comes out with what they want.” In the end, the murder of Dan Markel is a reminder that ordinary days can turn to tragedy in an instant, and that the bonds of family can either heal or destroy. For Markel, the ordinary drive home from the gym became the last moment of his life — and the beginning of a long, painful journey toward truth.
