Attorneys for Luigi Mangione, who pleaded guilty to federal stalking charges, are arguing that his plea triggers the double jeopardy clause, which could prevent his prosecution in state court for the murder of UnitedHealthcare CEO Brian Thompson. Mangione, 28, admitted to his role in a "single, tragic event" during a hearing Friday in Manhattan federal court.
Karen Friedman Agnifilo, a defense attorney, stated outside the courthouse that Mangione accepted full responsibility for Thompson's death with his guilty plea. She indicated the defense plans to file a motion in Manhattan criminal court to dismiss the state murder charges based on double jeopardy.
The Manhattan District Attorney's Office, however, signaled its intent to contest the defense's argument. A spokesperson for the office said they are prepared to litigate the defense motions and remain committed to seeking justice for Thompson and his family. The office has been preparing for a state trial since December 2024 and is set to begin jury selection on September 8.
Mangione faces a potential life sentence when he is sentenced in the federal case on December 18. His family expressed encouragement that Thompson's family received "a measure of accountability."
