Luigi Mangione has pleaded guilty to federal stalking charges related to the killing of UnitedHealthcare CEO Brian Thompson. In court, Mangione admitted, “I shot Mr. Thompson,” adding that he knew his actions were illegal.
Following the plea, his defense filed a motion seeking to dismiss the state charges, arguing that prosecuting him in both cases violates his constitutional protection against double jeopardy. Mangione’s federal sentencing is scheduled for December 18, while his state trial had been due to begin next month.
The case dates back to December 4, 2024, when New York City was rocked by the shooting of UnitedHealthcare CEO Brian Thompson. In the early hours of a busy Midtown Manhattan morning, Thompson was fatally shot in the street by a masked gunman who calmly walked away from the scene before reportedly using an e-bike to flee.
Five days later, Luigi Mangione was arrested at a McDonald’s in Pennsylvania and charged in connection with Thompson’s killing. Young, fit, and seemingly motivated by anger toward the US healthcare system, his arrest sent the media into a tailspin. The public has been divided over his alleged motives, with some condemning his actions and others praising him as a kind of hero of the people. Meanwhile, the Trump administration has made clear that it intends to seek the death penalty.
