Donna Adelson what did she do? The Florida grandmother was found guilty in September 2025 of masterminding the shocking 2014 murder-for-hire of her former son-in-law, Florida State University law professor Dan Markel. After nearly eleven years of speculation, arrests, and multiple trials, a Tallahassee jury delivered the verdict that officially tied the Adelson matriarch to the crime that has haunted both families for more than a decade.
The Verdict and Courtroom Reaction
The courtroom fell silent as the jury foreperson announced guilty verdicts for first-degree murder, conspiracy, and solicitation to commit murder. Donna Adelson, now 75, sobbed uncontrollably as the judge reprimanded her for disrupting proceedings. The Markel family, seated just feet away, described the decision as a long-awaited measure of justice for their son and brother.
Victim impact statements revealed the depth of pain suffered. Markel’s parents spoke directly to Adelson, describing years of loss and asking whether her actions had been worth the devastation. For many in attendance, the moment symbolized the closing of a painful chapter that began in July 2014.
Background of the Case
Dan Markel, a respected law professor, was shot in the head at close range in his Tallahassee garage. Investigators determined the killing was not random but a targeted hit connected to a bitter custody dispute between Markel and his ex-wife, Wendi Adelson, Donna’s daughter.
Over time, prosecutors built a case showing that the Adelson family had the motive, means, and connections to arrange the murder. Evidence included financial transactions, phone records, and testimony that pointed to Donna Adelson’s direct involvement in funding and encouraging the deadly plot.
Other Convictions in the Case
The case had already resulted in several convictions before Donna Adelson’s trial.
- Sigfredo Garcia, one of the hired gunmen, was sentenced to life in prison.
- Luis Rivera, the second hitman, accepted a plea deal and is serving a lengthy prison sentence.
- Katherine Magbanua, who acted as the go-between, was convicted and sentenced to life.
- Charlie Adelson, Donna’s son, was also convicted in 2023 and received a life sentence.
Donna was the final piece of the puzzle, long suspected but only arrested in late 2023 after authorities caught her attempting to board a one-way flight to Vietnam, a country without a U.S. extradition treaty.

Why Donna Adelson Was Convicted
Prosecutors argued that Donna was the driving force behind the plot. Frustrated by her daughter’s inability to relocate the grandchildren closer to the Adelson family in South Florida, she allegedly pushed for a permanent solution to remove Markel from the picture. Financial records tied her to the arrangements, and conversations captured over the years painted her as deeply involved in discussions about the murder.
Her arrest at the airport further supported claims that she knew her role in the conspiracy was closing in. Prosecutors described it as the final act of a woman who had spent years evading justice.
Impact on Families and Community
The Markel family has endured more than a decade of grief. While the conviction brings closure, it cannot restore the life of a beloved son, father, and scholar. For the Adelsons, the verdict adds another devastating blow, as multiple family members now face life behind bars.
The community in Tallahassee, particularly at Florida State University, has followed the case closely. For many, the outcome reinforces the importance of persistence in complex murder investigations, where justice may take years to achieve but ultimately prevails.
Looking Ahead
Donna Adelson’s sentencing hearing is scheduled for October 14, 2025. While she faces a mandatory life sentence for first-degree murder, the hearing will determine the formal terms of her punishment. Legal experts note that at her age, the conviction ensures she will spend the remainder of her life in prison.
The case will likely continue to be studied as an example of how family conflict and custody disputes can spiral into extreme and tragic outcomes. It has also raised broader conversations about the use of murder-for-hire schemes and how law enforcement uncovers complex webs of conspiracy.
