Luigi Mangione’s lawyers filed a motion to the New York Supreme Court seeking to have evidence suppressed and have his state charges for the assassination of UnitedHealthcare CEO Brian Thompson dismissed.

Mangione faces 11 charges in New York court over his alleged killing of Thompson on Dec. 4, 2024, outside the Hilton hotel in Midtown Manhattan. He has pleaded not guilty to state and federal charges against him. In the filing Thursday, Mangione’s lawyers argue that charging him for the alleged murder in both state court and federal court amounted to double jeopardy, according to the Associated Press.
