The Bitter Custody Battle: The Motive That Drove the Plot
The foundation of the entire murder-for-hire scheme was the acrimonious divorce and protracted custody battle between Donna Adelson’s daughter, Wendi Adelson, and her former husband, Dan Markel. Markel, a highly respected Florida State University Law Professor, was found shot in his Tallahassee driveway in 2014.
The Adelson family, particularly Donna, was reportedly obsessed with moving Wendi and the two young grandchildren from Tallahassee back to South Florida. Markel had successfully blocked Wendi's attempts to relocate the children, a decision that infuriated Donna Adelson.
Prosecutors successfully argued that Donna Adelson’s intense desire to relocate her grandchildren—and her perceived frustration with the legal system—was the driving force behind the murder. The Adelsons viewed Dan Markel as an obstacle that needed to be permanently removed. The emotional and financial strain of the custody dispute, combined with a strong desire for control, created the motive for the ultimate crime.
The Conviction and Life Sentence: The Case Against the Matriarch
Donna Adelson’s trial, which took place in 2025, was the culmination of a nearly decade-long investigation. The prosecution’s case relied heavily on a web of evidence that connected the Adelson family directly to the hired gunmen, including wiretaps, financial transactions, and testimony from co-conspirators.
The state presented evidence showing that Donna, along with her son Charlie Adelson, orchestrated the plot. Charlie Adelson, a wealthy dentist, was convicted and sentenced to life in prison in 2023 for masterminding the plot. The prosecution argued that the mother-son duo used their wealth and resources to contract the hit.
A crucial piece of evidence that led to Donna’s conviction was a series of recorded conversations and emails that revealed her deep involvement and controlling personality. The jury heard testimony detailing the family's attempts to manage the fallout and their discussions about the crime. Her conviction on September 4, 2025, for first-degree murder, conspiracy, and solicitation, made her the fifth person—and the second Adelson—to be found guilty in the case.
The Denial of a New Trial and Sentencing
Following the guilty verdict, Donna Adelson’s legal team filed motions seeking a new trial, but Circuit Judge Stephen Everett rejected these motions, paving the way for her sentencing. In October 2025, Donna Adelson was formally sentenced to life in prison. During the sentencing, the Markel family delivered powerful victim impact statements, highlighting the immense pain and loss caused by the Adelson family's actions.
The life sentence for Donna Adelson, a 75-year-old woman, ensures that she will spend the remainder of her life incarcerated, mirroring the sentence already handed down to her son, Charlie. This outcome was a significant victory for the prosecution and the Markel family, who had relentlessly pursued justice for their loved one.
The Adelson Family's Legal Future and Unanswered Questions
With both the matriarch and the mastermind, Donna and Charlie Adelson, now serving life sentences, the focus of the case shifts to the remaining members of the Adelson family.
Wendi Adelson: Dan Markel's ex-wife, Wendi Adelson, has consistently denied any knowledge or involvement in the murder. While she has not been charged, her proximity to the motive and the subsequent convictions of her mother and brother mean that she remains a figure of intense public and legal scrutiny. Prosecutors have indicated that the investigation into the entire family is ongoing, leaving open the possibility of future legal action.
Harvey Adelson: Donna's husband, Harvey Adelson, a wealthy dentist, has also not been charged. However, the use of the family's financial resources and the extensive nature of the conspiracy raise questions about the full extent of the family's knowledge and involvement. The legal community continues to debate whether the case against the Adelson family is truly closed.
The convictions of both mother and son serve as a stark reminder of the devastating consequences of the murder-for-hire plot. The Dan Markel case, which began as a simple custody dispute, has evolved into a chilling study of family dynamics, wealth, and criminal conspiracy, culminating in the life sentences of two of its central figures.
