Ten years. It took over a decade of legal gymnastics, secret FBI recordings in noisy Miami restaurants, and a family’s slow-motion collapse to finally get some answers. If you’ve been following the Dan Markel murder-for-hire saga, you know it’s basically a Shakespearean tragedy set in Florida. But keeping track of the headcount? That's the hard part.
As of early 2026, five people are currently in prison for the 2014 killing of the Florida State University law professor.
It’s a heavy number. It includes the "hitmen," the middlewoman, the "Maestro" brother, and most recently, the matriarch herself. If you’re looking for a quick tally of who is sitting in a cell right now, here is the breakdown:
- Charlie Adelson (The brother/son)
- Donna Adelson (The mother)
- Katherine Magbanua (The go-between)
- Sigfredo Garcia (The shooter)
- Luis Rivera (The driver/cooperator)
But honestly, the "who" is just as important as the "how many." This wasn't just a random act of violence. It was a cold, calculated hit motivated by a bitter custody battle that prosecutors say was financed and fueled by the Adelson family.
The Adelson Case: How Many are in Jail and Why it Took So Long
The wheels of justice in Tallahassee didn't just turn slowly; they practically seized up for years. For a long time, only the gunmen were behind bars. People in the legal community—and the "Justice for Dan" advocates—were screaming for years that the "Adelsons" (plural) needed to be held accountable.
The Hitmen: Garcia and Rivera
The first two to go down were the ones who actually made the drive from Miami to Tallahassee in a rented Toyota Prius. Sigfredo Garcia was convicted in 2019. He’s serving a life sentence without parole. He was the one who pulled the trigger in Markel’s driveway.
Then there’s Luis Rivera. He’s the only one on this list who isn't serving life. Why? Because he talked. Rivera took a plea deal for second-degree murder and got 19 years. He basically handed the state the roadmap to the rest of the conspiracy, explaining how they were hired and who the link was.
The Link: Katherine Magbanua
"Katie" Magbanua is the tragic figure in the middle of this mess. She was dating Charlie Adelson at the time of the murder, and she was the mother of Sigfredo Garcia’s children. Prosecutors successfully argued she was the bridge between the money (the Adelsons) and the muscle (Garcia/Rivera). After a hung jury in her first trial, she was finally convicted in 2022 and sentenced to life plus 60 years.
The Family Falls: Charlie and Donna Adelson
For nearly eight years, the Adelsons lived their lives in South Florida like nothing had happened. Charlie continued his career as a periodontist. Donna continued being the family matriarch. That ended in 2022 when the "Dolce Vita" recording—an undercover FBI tape from 2016—was finally enhanced and used to arrest Charlie.
Charlie Adelson was found guilty in November 2023. The jury didn't buy his "extortion" defense (where he claimed he was being blackmailed by the hitmen after the fact). He was sentenced to life in prison plus 60 years. As of right now, he's still fighting, with oral arguments for his appeal scheduled for February 2026. He’s trying to argue the trial should have been moved out of Tallahassee because everyone there knew too much about the case.
Donna Adelson, the 75-year-old grandmother, is the most recent addition to the prison roster. Her arrest was pure drama—she was caught at Miami International Airport in late 2023 trying to board a one-way flight to Vietnam (a country with no extradition treaty).
In September 2025, she was convicted of first-degree murder, conspiracy, and solicitation. In October 2025, a judge handed her a mandatory life sentence. Seeing her in a wheelchair, crying as the verdict was read, was a stark contrast to the defiant, controlling woman heard on the wiretaps.
The Big Question: What About Wendi and Harvey?
This is where the case gets controversial. If you’re counting how many are in jail over the Adelson case, the number is five. But the list of "unindicted co-conspirators" includes two more names: Wendi Adelson (Dan’s ex-wife) and Harvey Adelson (the father).
Wendi has never been charged. She has consistently denied any involvement, and she testified under derivative use immunity in the trials of her brother and mother. Prosecutors have been very careful here. While they have called her a co-conspirator in open court, they haven't pulled the trigger on an arrest warrant.
Harvey Adelson also remains free. At this point, many legal experts believe the state might be finished with their arrests, especially given Donna's conviction, but in this case, you can never say never.
A Quick Summary of Sentences:
- Donna Adelson: Life without parole + 30 years.
- Charlie Adelson: Life without parole + 60 years.
- Katherine Magbanua: Life without parole + 60 years.
- Sigfredo Garcia: Life without parole + 30 years.
- Luis Rivera: 19 years (expected release in the early 2030s).
Why This Case Still Matters
The Adelson case isn't just a "true crime" story; it's a case study in how wealth and privilege can delay—but not necessarily stop—the legal system. It's a reminder that digital footprints, like the "bump" the FBI used to trigger phone calls between Donna and Charlie, are nearly impossible to erase.
If you are following the case today, the next big thing to watch is Charlie Adelson’s appeal in February 2026. While it's a long shot, a successful appeal could upend the current count and lead to a retrial.
Next Steps for Following the Case:
Keep an eye on the Florida First District Court of Appeal records for the oral argument transcripts in Charlie’s case. Also, watch for any updates from the Leon County State Attorney's Office regarding the status of the remaining "unindicted" family members, as public pressure for "Justice for Dan" remains incredibly high.
