The "Adelson trial" refers to the series of high-profile legal proceedings involving members of the Adelson family—specifically Charles "Charlie" Adelson and his mother, Donna Adelson—who were charged in connection with the 2014 murder-for-hire of Florida State University law professor Dan Markel. As of 2026, these trials remain a landmark study in the use of electronic surveillance, undercover "bump" operations, and the prosecution of a multi-generational conspiracy.
The legal saga began on July 18, 2014, when Dan Markel was shot in the garage of his Tallahassee home. While the immediate triggermen were apprehended within years, it took nearly a decade to bring the suspected orchestrators to justice. The trials have focused on a motive rooted in a bitter custody dispute between Markel and his ex-wife, Wendi Adelson, whose family allegedly conspired to eliminate Markel to facilitate Wendi’s relocation to South Florida with their two children.
The Genesis of the Conspiracy: Motive and the Custody Dispute
To understand the Adelson trials, one must first examine the legal and personal friction that preceded the murder. Dan Markel and Wendi Adelson, both accomplished legal scholars, underwent a contentious divorce in 2013. A central point of conflict was Wendi’s desire to move from Tallahassee to the Miami area to be closer to her family.
In 2013, a judge denied Wendi’s motion to relocate with the children, a ruling that effectively anchored her to Tallahassee as long as Markel shared custody. Prosecutors argued during the trials that this ruling served as the catalyst for the Adelson family’s decision to take extra-legal measures. The state’s theory posited that the Adelsons viewed Markel as an obstacle that needed to be removed to grant Donna Adelson greater access to her grandchildren.
The financial and logistical planning of the crime allegedly flowed through Charlie Adelson, a successful periodontist and Wendi’s brother. Charlie was positioned as the intermediary between the family and the individuals who carried out the killing. This "middleman" structure was designed to insulate the Adelsons from the actual violence, though it eventually became the very mechanism that led to their downfall through the testimony of Katherine Magbanua.
The Trial of Charlie Adelson (November 2023)
The trial of Charlie Adelson served as the centerpiece of the state's prosecution against the family. Charlie was charged with first-degree murder, conspiracy to commit murder, and solicitation of murder. The trial, which concluded in November 2023, was a masterclass in the presentation of circumstantial and technical evidence.
The Defense's "Extortion" Theory
One of the most notable aspects of Charlie Adelson's trial was his unusual defense strategy. Charlie took the stand—a risky move in a murder trial—and admitted that he had paid the killers, but claimed he did so because he was being extorted. He argued that Katherine Magbanua and the hitmen had killed Markel on their own initiative and then pressured him for money, threatening his own life if he did not comply.
The prosecution successfully dismantled this theory by pointing to the timeline of communication between Charlie and the conspirators. They argued that if Charlie were truly a victim of extortion, his behavior after the murder—including continued social and intimate relations with Magbanua—was inconsistent with that of a man fearing for his life.
The "Bump" Operation and the Dolce Vita Recording
A pivotal piece of evidence was the 2016 undercover FBI operation known as "The Bump." An undercover agent approached Donna Adelson on a sidewalk, handed her a flyer about the Markel murder, and demanded money, pretending to be associated with the hitmen. This "bump" was designed to trigger panicked communications among the suspects.
The plan worked. Following the encounter, Charlie and Donna engaged in a series of guarded but incriminating phone calls and met at a Miami restaurant called Dolce Vita. Despite the background noise of the restaurant, the FBI used advanced audio filtering to capture Charlie discussing the "bump" and the potential legal exposure they faced. This recording, often referred to as the "Dolce Vita tape," was played extensively during the trial, providing the jury with a direct window into the family’s inner circle.
The Verdict and Sentencing
On November 6, 2023, after only a few hours of deliberation, the jury found Charlie Adelson guilty on all counts. He was subsequently sentenced to life in prison without the possibility of parole. His conviction was a turning point, as it established the legal link between the hitmen and the Adelson family.
The Arrest and Prosecution of Donna Adelson
Shortly after Charlie’s conviction, the legal focus shifted to the family matriarch, Donna Adelson. For years, investigators had scrutinized her involvement, but it was her actions following Charlie's guilty verdict that precipitated her arrest.
The Attempted Flight
In November 2023, Donna and her husband, Harvey Adelson, were intercepted by authorities at Miami International Airport. They had purchased one-way tickets to Vietnam, a country with which the United States does not have an extradition treaty. Prosecutors used this attempted flight as evidence of "consciousness of guilt."
Donna Adelson was charged with first-degree murder, conspiracy, and solicitation. Her prosecution underscored the state's belief that she was a primary driver of the plot, frequently communicating her frustration with Markel and her desire to have the children relocated at any cost.
Evidentiary Challenges in Donna’s Case
The case against Donna relied heavily on her recorded phone calls with Charlie after his arrest and her emails to Wendi expressing intense animosity toward Markel. Unlike Charlie, who was linked to the hitmen through his girlfriend (Magbanua), Donna’s link was largely financial and motivational. The prosecution aimed to show that she authorized the payments—some of which were allegedly disguised as "checks" from the family’s dental practice.
Key Co-Conspirators and Their Roles
The Adelson trials were only possible due to the prior convictions of the individuals who physically carried out the crime. The state used a "bottom-up" prosecution strategy, securing convictions or pleas from the hitmen before moving on to the Adelsons.
- Sigfredo Garcia: Identified as one of the two hitmen who traveled from Miami to Tallahassee to shoot Markel. He was convicted of first-degree murder in 2019 and sentenced to life in prison.
- Luis Rivera: The second man in the car and a leader of the Latin Kings gang. Rivera took a plea deal in 2016, testifying against Garcia and Magbanua in exchange for a 19-year sentence. His testimony provided the first inside look at how the hit was coordinated.
- Katherine Magbanua: The "link" between the Adelsons and the hitmen. She was Charlie Adelson’s girlfriend and the mother of Sigfredo Garcia’s children. After an initial mistrial, she was convicted of first-degree murder in 2022 and sentenced to life. Her eventual cooperation (though late) was significant for the state's case against Charlie.

The Role of Wendi Adelson
Wendi Adelson remains the most enigmatic figure in the legal proceedings. While she has never been charged with a crime, her presence looms over every trial. She testified in the trials of Garcia, Magbanua, and her brother Charlie under a grant of use immunity, meaning her testimony cannot be used against her in a future prosecution unless she commits perjury.
The "TV Repair" Coincidence
A major point of contention in the trials was Wendi’s behavior on the day of the murder. She famously drove toward the crime scene while the police were still there, claiming she was going to a liquor store and noticed the tape. She also told investigators about a "joke" her brother Charlie had made about hiring a hitman as a divorce present.
Prosecutors have questioned the timing of her actions, including her decision to change the children’s last names from Markel to Adelson shortly after the murder. Despite these suspicions, the state has maintained that they will only bring charges if and when they have sufficient evidence to secure a conviction beyond a reasonable doubt.
Legal and Forensic Innovations in the Case
The Adelson trials are notable for several technical and legal reasons that have influenced how complex conspiracy cases are handled in Florida.
Advanced Audio Forensics
The recovery of the Dolce Vita restaurant recording was a technological milestone. The FBI's ability to isolate human speech from significant ambient noise—clinking silverware, other patrons, and background music—turned a nearly unusable tape into the state’s "smoking gun." This case is frequently cited in discussions regarding the admissibility and processing of covertly recorded evidence.
Use of the "Bump" as a Tactical Tool
The use of an undercover agent to "bump" a suspect is a common federal tactic, but its application in a state-level murder-for-hire case was executed with surgical precision here. By monitoring the immediate aftermath of the "bump," investigators were able to bypass the "radio silence" the Adelsons had maintained for nearly two years.
The Markel Act (Grandparent Visitation Rights)
The human toll of the case led to legislative changes in Florida. Following the murder, Dan Markel's parents, Ruth and Phil Markel, were largely cut off from their grandchildren by Wendi Adelson. This led to the passage of Section 752.011, Florida Statutes, often called the "Markel Act." The law allows grandparents to petition for visitation rights if a parent has been killed and the other parent is "responsible" for the death, or if there is a history of certain criminal activity.
Frequently Asked Questions
Why was Charlie Adelson not arrested until 2022?
Investigators lacked a direct link between Charlie and the hitmen until the "Dolce Vita" recording was fully processed and Katherine Magbanua was convicted. The state chose to wait until they had a "triangulated" case where the testimony of the hitmen and the facilitators could be corroborated by technical evidence.
Is Wendi Adelson still under investigation?
The State Attorney's Office has consistently stated that the investigation into Dan Markel’s murder remains open. While Charlie and Donna have been the primary targets of recent years, the status of Wendi Adelson remains a "person of interest" whose involvement continues to be scrutinized as new evidence from the family trials emerges.
What happened to Harvey Adelson?
As of 2026, Harvey Adelson, the father of Charlie and Wendi, has not been charged with a crime. Although he was present during the attempted flight to Vietnam, prosecutors have not publicly released evidence sufficient to charge him with conspiracy or solicitation.
What is the significance of the "stapled money"?
During the trials, Luis Rivera testified that the money he received for the hit was stapled in a specific way. This detail was significant because Wendi Adelson had previously mentioned in her police interview that her family’s dental practice (Adelson Institute) used a unique method of stapling cash and documents, creating a forensic link between the hitmen’s payment and the Adelson business.
How long did it take to solve the Dan Markel case?
The case was not "solved" in a single moment. It was a 12-year progression from the shooting in 2014 to the ongoing trials in the mid-2020s. The first arrests occurred in 2016, with Charlie Adelson’s conviction following seven years later in 2023.
Summary of Current Status and Next Actions
The Adelson trials represent one of the most complex murder-for-hire prosecutions in U.S. history. With Charlie Adelson serving life and Donna Adelson's legal proceedings continuing to unfold, the focus has shifted toward the finality of justice for the Markel family.
For those following the case, the next critical developments will likely involve the resolution of Donna Adelson's trial and any potential movement regarding the remaining family members. Legal observers recommend monitoring the Second Judicial Circuit of Florida for updated court filings and scheduling. Additionally, the Markel family continues to advocate for the rights of victims' families through the Justice for Dan Markel initiatives, providing a roadmap for legislative changes in grandparent rights and victim advocacy.
