After leaving the gym, Dan Markel drove home expecting an ordinary day. Instead, his killer was waiting for him.
As he arrived home, the prominent Florida State University law professor was talking on the phone with music teacher Stewart Schlazer about school options for his children. Then the conversation took a terrifying turn.
“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.”
“There are really eerie parts of those final hours,” producer Lily 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.”

“It’s always reminded me of a shark circling,” Fletcher said. “There was something just so sinister and eerie during such a mundane part of his day, just going to the gym. That really stayed with me. That’s a really chilling part, just watching that footage.”

Markel was shot in the head while sitting in his car in the garage of his Tallahassee, Florida, home on July 18, 2014. The 41-year-old died the following day.
The case is the subject of a new true crime docuseries from ABC News Studios, “Welcome to the Family: The Murder of Dan Markel,” now streaming on Hulu.

It features exclusive interviews, including with FBI agent Pat Sanford and a recorded conversation with Rob Adelson, the oldest Adelson son, who testified against his mother, Donna Adelson, at her trial. It largely follows the prosecution’s investigation and trial evidence, while also including testimony and recordings introduced during court proceedings.

Markel married Wendi Adelson in 2006 after the two met online. The docuseries depicts prosecutors’ theory that Wendi’s mother, Donna, was a dominating, controlling figure in their lives with strong opinions about her daughter’s choices.

Wendi later said the couple’s marriage fell apart after they had two sons, Benjamin and Lincoln. Their contentious divorce in 2013 centered on one question: where the boys would grow up. Wendi fought to move them to South Florida to be near her family, while Markel pressed to keep them in Tallahassee, where the parents shared custody.
According to the docuseries, Donna was furious after the relocation request was denied.

Prosecutors said the custody dispute became the catalyst for a murder-for-hire plot that would take years to unravel. They argued at trial that Donna helped orchestrate Markel’s killing after he stood in the way of letting her daughter and two young grandsons make the move south.
They also revealed that her son Charlie Adelson arranged for Markel’s killing through his then-girlfriend, Katherine Magbanua, who connected him to Sigfredo Garcia, the father of her children, and Garcia’s friend Luis Rivera.

Prosecutors said Garcia shot Markel while Rivera drove the getaway car. Over the next decade, investigators used cellphone records, surveillance video, financial records and secretly recorded conversations to build the case.
“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.

“And I think 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.”

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, however, insisted the state didn’t have sufficient evidence to link her to the murder plot.

In 2023, Charlie, a dentist, was convicted of first-degree murder, conspiracy to commit murder and solicitation to commit murder in his former brother-in-law’s killing. Prosecutors told jurors that Charlie paid to have Markel killed and used Magbanua to hire Garcia. They said Garcia enlisted the help of Rivera, his childhood friend.

Charlie testified that he had nothing to do with the killing and was stunned when Magbanua came to his home and said her friends were the killers. According to reports, he also said he needed to pay more than $300,000 in 48 hours or he would be killed. He was sentenced to life in prison.

While Fletcher said the surveillance video is one of the documentary’s most haunting moments, she believes the hundreds of FBI wiretap recordings provide the clearest window into the Adelson family.

“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.”

“Fletcher said listening to the wiretaps left her with the impression that some family members believed they would avoid accountability.
“They weren’t used to not getting their way,” Fletcher continued. “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 said the conversations showed her how deeply Donna and Charlie involved themselves in Wendi’s personal life.

“It’s hours and hours of conversations,” Fletcher said. “It’s Donna encouraging Charlie, and Charlie is suggesting to his mother as well that he will go and speak to Wendi. 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.”

Wendi has repeatedly denied any involvement in her ex-husband’s killing and has not been charged.
“I don’t know why people online have such strong levels of certainty,” Fletcher 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.”

“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.”
