Donna Adelson is a 75-year-old matriarch of a wealthy South Florida family who was convicted and sentenced to life in prison for her involvement in the 2014 murder-for-hire killing of her former son-in-law, Daniel Markel, a law professor at Florida State University. She was found guilty of first-degree murder, conspiracy, and solicitation related to the killing, which was connected to a bitter custody dispute between Markel and Adelson's daughter, Wendi Adelson. Donna Adelson has maintained her innocence and plans to appeal the verdict but was criticized by the judge for showing an "utter lack of remorse" during sentencing.
