Luigi Mangione, 28, has pleaded guilty to two federal charges of interstate stalking resulting in death, admitting to shooting UnitedHealthcare CEO Brian Thompson, 50, on December 4, 2024, in Manhattan. Mangione stated his actions were motivated by severe back pain and negative experiences with the healthcare system. He admitted to planning the attack, traveling across state lines, and using a 3-D-printed gun equipped with a silencer. Thompson, a father of two, was shot from behind as he entered a hotel. Mangione faces a maximum sentence of life in prison, with sentencing scheduled for December 18.
