Luigi Mangione’s state murder trial in the killing of UnitedHealthcare CEO Brian Thompson has been postponed indefinitely. His lawyers are seeking to have the case dismissed on double jeopardy grounds after Mangione pleaded guilty to federal charges last week. Judge Gregory Carro issued an order Monday canceling the Sept. 8 trial and giving the Manhattan District Attorney's office until Oct. 9 to respond. A hearing is set for Dec. 10. Mangione admitted to stalking and killing Thompson in 2024. Federal prosecutors are seeking life in prison, though guidelines suggest 24 to 30 years. Mangione's lawyers argue he's being punished twice for the same conduct.
