Double jeopardy could spell end of state case after Luigi Mangione’s guilty plea

Defense argues New York cannot try Mangione over same act or offense as federal case – the killing of Brian Thompson

Luigi Mangione’s plea to federal stalking charges in UnitedHealthcare CEO Brian Thompson’s death has spurred questions about the fate of the separate Manhattan murder case against him, with experts saying New York’s double-jeopardy law could derail that trial.

Mangione pleaded guilty to one count of interstate stalking resulting in death, and one count of cyberstalking through use of interstate facilities resulting in death, in connection with the 4 December 2024 shooting outside a Midtown hotel. Both charges carry a potential maximum life sentence.
