Luigi Mangione pleaded guilty to federal stalking charges on Friday. These charges are connected to the 2024 killing of UnitedHealthcare CEO Brian Thompson. A conviction in federal court could have resulted in a life sentence for Mangione. His guilty plea might lead to the dismissal of separate state charges, including second-degree murder. Mangione's defense team argued that being tried in both federal and state courts violates double jeopardy protections. His federal trial on stalking counts was initially scheduled for January 2027. During the hearing, the judge indicated Mangione must serve a significant portion of his federal sentence. Mangione is accused of fatally shooting Thompson in Manhattan in December 2024. He was arrested in Pennsylvania on unrelated charges after a manhunt. Mangione has expressed contempt for the health insurance industry in a manifesto. He still faces a New York state trial next month for murder charges.
