Prosecutors have long maintained that Wendi Adelson was involved in the murder-for-hire plot that killed her ex-husband, Florida State University law professor Dan Markel, and they have formally identified her as an unindicted co-conspirator in court filings. She has never been arrested or charged. The chief reason is not a lack of suspicion but a legal problem the state created when it put her on the witness stand under a grant of immunity.
Her mother, her brother, and three other people have been convicted of planning or carrying out the July 2014 killing. Wendi Adelson has denied any knowledge of the plot.
What Prosecutors Say Her Role Was
The state’s theory of the case begins with a custody fight. Markel and Adelson divorced in 2013, and the central dispute was whether Wendi could relocate with the couple’s two young sons from Tallahassee to South Florida, where her family lived and where the Adelsons ran a dental practice. Markel opposed the move and won. A Florida judge ruled the children would stay in Tallahassee.
Prosecutors have argued that ruling is what set the murder plot in motion. As long as Markel was alive and exercising his parental rights, Wendi could not bring the children south. Her family, prosecutors said, treated Markel as an obstacle to be removed. The conspiracy they laid out at trial ran from Charlie Adelson, Wendi’s brother, through his on-and-off girlfriend Katherine Magbanua, to the two men who drove to Tallahassee and carried out the shooting, Sigfredo Garcia and Luis Rivera. Financial records traced payments from the Adelson family to Magbanua and from Magbanua to Garcia.
Wendi Adelson sat at the center of the motive the state described: she was the person who stood to benefit from the move the court had blocked, and she was the member of the family whose life changed if Markel were gone. Prosecutors have stopped short, in public, of saying exactly what they believe she knew and when. The unindicted co-conspirator label signals that investigators think she was part of the plan without committing the state to a charge it is not yet prepared to prove.
Why She Hasn’t Been Charged
Wendi Adelson testified at her brother Charlie’s 2023 trial under a grant of use immunity. That means the prosecution cannot use anything she said on the stand, or anything derived from what she said, against her in a future case. On the stand she repeatedly denied knowing about the murder plot and clashed with prosecutors over inconsistencies in her prior statements.
If the state ever decides to charge her, it would first have to clear a hearing named after the 1972 U.S. Supreme Court decision in Kastigar v. United States.1Justia US Supreme Court. Kastigar v. United States, 406 U.S. 441 (1972) At a Kastigar hearing, the burden sits with the prosecution. The state must affirmatively prove that every piece of evidence it intends to use against her came from a source wholly independent of her immunized testimony. It is not enough to show the evidence looks untainted. Prosecutors have to trace each item back to an origin that existed and was known to investigators separately from anything she told them under immunity.
Analysts who have followed the case describe this as a high bar, and it is the practical reason a charging decision has not come. Every witness the state might call, every document it might introduce, every theory it might argue would be scrutinized for whether it was shaped, even indirectly, by her immunized words.
The Statute of Limitations Is Not a Barrier
Time is not on the state’s side strategically, but it is not against it legally. Under Florida law, there is no statute of limitations on a capital felony, a life felony, or any felony that resulted in a death.2The Florida Legislature. Florida Statutes 775.15 – Time Limitations; General Time Limitations; Exceptions First-degree murder and conspiracy to commit murder both fall inside that exception. Charges against Wendi Adelson could theoretically be brought at any point, years or decades from now, if prosecutors ever conclude they can satisfy Kastigar.
Where the Other Convictions Leave Her
The case against the rest of the alleged conspiracy has been resolved. Luis Rivera pleaded guilty to second-degree murder and received 19 years in exchange for his cooperation. Sigfredo Garcia, identified as the triggerman, was convicted of first-degree murder in 2019 and sentenced to life without parole. Katherine Magbanua was convicted at a 2022 retrial after her first jury hung, and received a mandatory life sentence. Charlie Adelson was convicted of first-degree murder, conspiracy, and solicitation in November 2023, and sentenced to life plus 30 years. At sentencing he said, “I would just like to say that I maintain my innocence.”
Donna Adelson, Wendi’s mother, was arrested days after Charlie’s conviction on the jet bridge at Miami International Airport as she tried to board a one-way flight to Vietnam, which has no extradition treaty with the United States. A Leon County jury convicted her in September 2025 of first-degree murder, conspiracy, and solicitation after deliberating a little over three hours. She was sentenced in October 2025 to life plus 30 years and filed a notice of appeal the following month. The case is pending before Florida’s First District Court of Appeal.3Florida Courts ACIS. Adelson v. State of Florida, Case No. 1D2025-2848
The convictions have left Wendi Adelson in an unusual position. The jurors who heard the state’s case against her brother and her mother were persuaded, beyond a reasonable doubt, that both participated in a plot to kill Dan Markel. The same evidence that convinced those juries forms the backdrop against which prosecutors continue to describe Wendi as an unindicted co-conspirator. She has not, however, had to answer those allegations in a trial of her own, and under the law she is not required to.
Potential Civil Liability
A criminal charge is not the only way Wendi Adelson could face a courtroom. Florida law imposes no statute of limitations on wrongful death claims arising from intentional torts, including murder. Whether the Markel family has filed or intends to file a civil action against the Adelsons has not been made public. The window remains open indefinitely. A civil case would require only a preponderance of the evidence, a lower standard than the proof beyond a reasonable doubt that has governed the five criminal convictions in the case so far.
For now, the answer to whether Wendi Adelson was involved depends on who is answering. Prosecutors say yes, in filings and in open court. A jury has never been asked.
