Manhattan prosecutors on Friday filed paperwork opposing Luigi Mangione's arguments to dismiss state-level charges stemming from the killing of UnitedHealthcare executive Brian Thompson. Mangione pleaded guilty to federal stalking charges on August 14 for Thompson's death outside a Midtown hotel on December 4, 2024. His legal team subsequently filed a motion to dismiss the state murder and weapons case, citing New York's double jeopardy law, which prohibits individuals from being prosecuted twice for the same offense or for multiple offenses based on the same criminal transaction.
Judge Gregory Carro, overseeing the state case, has postponed proceedings and scheduled the next court date for December 10. Prosecutors were given an October 9 deadline to respond to Mangione's dismissal arguments, with his defense having until October 30 to reply.
Prosecutors contend that an exception to the state's double jeopardy law permits the murder case to proceed. They argue that the elements of the federal stalking charges, to which Mangione pleaded guilty, and the state murder charges are distinct and do not overlap in a manner that would trigger double jeopardy protections. Regarding weapons charges, prosecutors noted that federal weapons counts against Mangione were dismissed, and statutory double jeopardy applies only to separate prosecutions for the same misconduct.
