Donna Adelson is a Florida woman and former dental office bookkeeper best known for her conviction in the 2014 murder-for-hire killing of her former son-in-law, Dan Markel. Her name became a fixture in national headlines after a wiretap-heavy criminal case tied her, her husband, and her son to a plot born out of a bitter custody dispute. She spent years denying any role in the murder before a Tallahassee jury found her guilty in 2025. This article walks through her age, family life, career, trial, and financial standing in plain, factual terms.
Who is Donna Adelson?
Donna Adelson is the South Florida matriarch convicted of orchestrating the murder-for-hire plot that killed Dan Markel, her former son-in-law. Before she became a household name in true crime circles, she lived a fairly ordinary life. She worked for decades inside her husband’s dental office, raised three children, and stayed largely out of the public eye.
That changed once investigators connected her family to the 2014 shooting of Markel, a Florida State University law professor. Markel was gunned down in his own garage in Tallahassee, and it took nearly a decade of investigation before charges reached the top of the family tree. Donna Adelson’s case became one of the most closely watched criminal trials in Florida in recent memory, drawing national media attention from outlets far beyond the state.
Her daughter, Wendi Adelson, had been locked in a custody dispute with Markel following their divorce. Prosecutors argued that Donna Adelson wanted her daughter and grandchildren moved to South Florida, and that this desire eventually turned into a plan to remove Markel from the picture permanently. She has consistently pleaded not guilty and maintains her innocence to this day.

A lot of fields say “not publicly disclosed,” and that’s on purpose. Donna Adelson didn’t build a public persona before her arrest. She’s a private citizen who became famous through a criminal case, not through choice, so a lot of personal details simply never entered the public record.
Donna Adelson Age
Donna Adelson was 75 years old at the time of her October 2025 sentencing, which puts her birth year around 1950. She was 73 when authorities arrested her at Miami International Airport in November 2023.
Her age became a talking point throughout the trial. Defense attorneys leaned on her status as an aging grandmother to argue she couldn’t have been the mastermind prosecutors described. The state pushed back hard, describing her instead as a sharp, calculating matriarch who ran her family’s finances for decades and knew exactly what she was doing. The jury sided with the prosecution.
Donna Adelson Trial
The Donna Adelson trial ran for roughly two weeks in Tallahassee, starting with jury selection on August 19, 2025. It became the fifth and final major trial connected to the Dan Markel murder-for-hire case.
Background of the Dan Markel Murder Case
Dan Markel, a well-known Florida State University law professor, was shot and killed in his driveway in July 2014. He had been fighting a custody battle with his ex-wife, Wendi Adelson, over their two young sons. Investigators believed for years that someone close to the Adelson family paid for the hit, but building a case against the family took nearly a decade.
Four other people were convicted before Donna Adelson ever stood trial: hitman Sigfredo Garcia, gang member Luis Rivera, go-between Katherine Magbanua, and her own son, Charlie Adelson, a Fort Lauderdale periodontist. Charlie’s conviction in November 2023 set off the final chapter of the case.
Donna Adelson’s Arrest and Charges
Just days after Charlie Adelson’s guilty verdict, Donna Adelson and her husband Harvey were intercepted at Miami International Airport. They held one-way tickets to Vietnam, routed through Dubai, a country with no extradition treaty with the United States. Prosecutors said the timing wasn’t a coincidence. Investigators had already built a case against her, and her attempt to leave the country forced them to move faster than planned.
She faced first-degree murder, conspiracy to commit murder, and solicitation to commit murder. She was booked without bond and pleaded not guilty to every charge.
Donna Adelson Trial Verdict and Sentencing
On September 4, 2025, a jury found Donna Adelson guilty on all three counts after roughly three hours of deliberation. She became the fifth person convicted in the plot to kill Dan Markel.
Her defense team requested a new trial afterward, citing possible juror misconduct, but Judge Stephen Everett denied that motion. On October 13, 2025, the court sentenced her to life without parole for first-degree murder, plus an additional 30 years on the conspiracy and solicitation charges, to run consecutively.
At sentencing, Adelson addressed the court for the first time in the case, denying any involvement and calling her conviction a miscarriage of justice. Her husband Harvey also spoke, accusing the judge and jury of bias. Judge Everett agreed to recommend she serve her sentence near Miami so she could remain close to her husband. She has filed a notice of appeal.
Key Moments from the Courtroom
A few pieces of evidence stood out during the trial:
- FBI undercover recordings that captured conversations prosecutors said linked Donna to the murder conspiracy and payment arrangements
- Signed checks connecting the dental practice’s finances to intermediary Katherine Magbanua
- Jailhouse phone calls prosecutors said contained coded references to money and pressure
- Testimony describing a roughly $138,000 payment tied to the plot
- Prosecutors’ closing argument, which framed her as the family’s calculating and controlling matriarch
The defense countered that the state lacked direct evidence tying Donna to the murder itself, and tried to shift suspicion toward other family members. The jury didn’t buy it.
Donna Adelson Early Life
Details about Donna Adelson’s early life remain scarce. She was born around 1950 in Florida and grew up in what’s been described as a middle-class household. Records about her parents, siblings, or early education haven’t surfaced publicly, and no verified information exists about where exactly she spent her childhood.
What is known is that she met Harvey Adelson and married him in the 1970s. From there, the couple built both a family and a business together, settling in South Florida, where they would remain for decades.
Donna Adelson Family Details
Husband, Harvey Adelson
Harvey Adelson is a retired dentist who founded the family’s dental practice in Tamarac, Florida. He was present at the Miami airport when his wife was arrested but has never been charged in the case. He’s remained publicly vocal in her defense, calling the trial’s outcome unjust and standing by her innocence throughout.
Children, Charlie and Wendi Adelson
Charlie Adelson, a periodontist by training, was convicted in November 2023 of first-degree murder, conspiracy, and solicitation for his role in orchestrating the killing. He’s currently serving a life sentence.
Wendi Adelson, Dan Markel’s ex-wife, has not been charged in the case. She has publicly denied any involvement in the murder plot. The custody dispute between Wendi and Markel over their two sons sat at the center of the prosecution’s theory of motive for the entire family.
A third child, Robert Adelson, has largely stayed out of the public record connected to the case.
Grandchildren
Wendi and Dan Markel had two young sons together. Out of respect for their privacy as minors, most reporting has avoided identifying details about them beyond confirming their existence and their role in the underlying custody dispute.
Extended Family Dynamics
The case exposed deep cracks inside a family that once presented itself as close-knit and prosperous. What started as a private custody fight spiraled into a criminal conspiracy that consumed nearly every branch of the family tree. By the time Donna Adelson’s trial wrapped up, four family members and associates were already serving life sentences, and the family’s once-quiet dental business had become a symbol of the plot itself.
Donna Adelson Career Highlights
Donna Adelson’s professional life centered almost entirely on her husband’s dental practice. She worked for years at the Adelson Institute for Esthetics and Implant Dentistry in Tamarac, handling bookkeeping duties and later serving as a patient care coordinator.
Her role wasn’t glamorous, but it was central to how the family business ran. She managed payroll, signed checks, and oversaw day-to-day cash flow. Prosecutors later pointed to this financial access as part of their case, arguing that her control over the practice’s money gave her the means to fund parts of the murder plot, including payments that flowed to Katherine Magbanua.
Outside of the dental practice, there’s no documented independent career or business ventures tied to her name. Her professional identity was, for most of her adult life, tightly woven into her husband’s practice and her family’s finances.
Donna Adelson Birthday
Donna Adelson’s exact birth date hasn’t been made public, though her age at trial places her birth year around 1950. Given the sensitivity of the case and her status as a convicted felon rather than a public figure, specific birthday details haven’t been reported by credible outlets and shouldn’t be assumed or guessed at.
Donna Adelson Net Worth
Donna Adelson’s estimated net worth sits somewhere between $500,000 and $2 million, based on financial reporting tied to her trial and pre-arrest assets. Before her 2023 arrest, some estimates placed her financial holdings closer to the higher end of that range. Legal defense costs since then have reportedly chipped away at the family’s overall wealth.
Her income never came from a high-profile career or public ventures. It came from decades of steady work inside the family dental practice, which by most accounts was a financially successful operation. The Adelsons owned a five-bedroom home in Coral Springs, and prosecutors argued during trial that the family had more than enough financial resources to fund an attempted international flight to Vietnam.
| Net Worth Estimate | Timeframe |
| $1 million to $2 million | Pre-arrest estimate, before November 2023 |
| $500,000 to $1 million | Estimated post-conviction, reflecting legal costs |
It’s worth noting that net worth figures for private individuals caught up in criminal cases are almost always estimates. No court filing has published an exact figure for her personal assets, so any number should be read as a reasonable estimate rather than a confirmed fact.

Donna Adelson Controversies
The murder-for-hire case is, by a wide margin, the defining controversy of Donna Adelson’s life. There’s no meaningful public record of controversy tied to her before the Markel case surfaced.
Within the case itself, a few specific moments generated their own waves of public scrutiny:
- Her attempted flight to Vietnam days after her son’s conviction, which many saw as an implicit admission of guilt
- Her defense team’s post-verdict claim of juror misconduct, which the judge rejected
- Her husband’s courtroom outburst at sentencing, accusing the judge of bias
- Ongoing tension between the Adelson and Markel families, which played out publicly through victim impact statements and media interviews
The case also fueled broader public conversation about custody disputes turning violent, and about how far family loyalty can be stretched before it crosses into criminal conspiracy.
Where is Donna Adelson Now?
Donna Adelson is currently serving a life sentence without parole, plus an additional 30 years, following her October 2025 sentencing. Judge Everett recommended she be placed in a Florida Department of Corrections facility as close to Miami as possible, so she can remain near her husband.
She has filed a notice of appeal challenging both pretrial rulings and her conviction. As with most appeals in serious felony cases, this process is expected to take considerable time, and there’s no confirmed timeline for a ruling. For now, her case status remains “convicted and sentenced, appeal pending.”
