What is the episode about?
Dan Markel, a renowned law professor at Florida State University, was shot twice in the head on July 18, 2014, in his garage in Tallahassee, shortly after returning home from a workout at the local gym. In this episode of Dateline NBC correspondent Dennis Murphy reconstructs the years-long investigation that transformed a tragic shooting into one of the most sensational murder-for-hire cases in American legal history. The episode Deadly Mischief highlights how police were able to track the perpetrators from Miami to northern Florida and further into the wealthy Adelson family through surveillance footage of a light Toyota Prius and extensive bank statements.
The case behind the episode
The case of Dan Markel began with a bitter divorce and custody battle between Markel and his ex-wife, Wendi Adelson. The investigation revealed that the murder was not a random robbery but a meticulously planned execution carried out by Sigfredo García and Luis Rivera, two gang members connected to Katherine Magbanua. Magbanua acted as the link to Wendi Adelson's brother, Charlie Adelson, who, according to prosecutors, financed the murder to fulfill the family's desire for Wendi and the children to move to South Florida.
Over the years, the case has evolved with several trials. Luis Rivera entered a plea deal and testified against the others involved, leading to the conviction of Sigfredo García and later Katherine Magbanua. In 2023, Charlie Adelson was found guilty of aiding and abetting murder, and the episode also covers the dramatic arrest of the family's matriarch, Donna Adelson, at Miami International Airport while she attempted to flee to Vietnam. A key piece of evidence in the case is the so-called bump operation, where an undercover agent confronted Donna Adelson with information about the murder, triggering a series of incriminating phone calls between her and her son.
