Luigi Mangione's state murder trial for the killing of UnitedHealthcare CEO Brian Thompson has been postponed indefinitely by a New York state judge. The trial, originally slated to begin September 8, was canceled as Mangione's lawyers seek to have the case dismissed on double jeopardy grounds following his guilty plea last week to federal charges.
Judge Gregory Carro has given the Manhattan District Attorney’s office until October 9 to respond to the defense's double jeopardy claims. A hearing is scheduled for December 10, approximately a week before Mangione's federal sentencing on December 18. Mangione pleaded guilty to federal charges of interstate stalking resulting in death and stalking through use of interstate facilities resulting in death, admitting to shooting Thompson outside a Manhattan hotel in 2024.
Mangione's lawyers argue that prosecuting him in state court after a federal guilty plea constitutes double jeopardy, describing him as a "pawn in parallel prosecutions." They contend that the conduct for both the federal stalking charges and the state murder and weapons charges are part of the same criminal incident. The Manhattan District Attorney's office, however, plans to fight the dismissal, arguing that the state charges involve different legal elements and that Mangione's federal sentence is not yet known.
