Luigi Mangione's New York state trial on murder and weapons charges over the 2024 killing of a health insurance CEO has been postponed after he pleaded guilty last week to separate federal charges. The trial had been due to begin on September 8, but New York state Justice Gregory Carro gave prosecutors until October 9 to respond to Mangione's motion to dismiss the state case and scheduled his next court appearance for December 10. Mangione has pleaded not guilty to the state charges. His lawyers argue that New York's double jeopardy protections bar the state from punishing him twice for the same conduct following his federal guilty plea.
