Mangione, 28, is accused of ​shooting UnitedHealthcare CEO Brian Thompson outside a hotel in December 2024. The killing was widely condemned by public officials but became emblematic of many peoples' frustration with health insurance industry practices in the United States. Mangione has pleaded not guilty to murder, weapons and forgery charges brought by Manhattan District Attorney Alvin Bragg. Thompson led UnitedHealth Group's insurance unit before he was shot dead in the early morning outside a hotel where an investor conference was taking place. Graphic footage of the killing and a five-day manhunt ​for a suspect made the case a media fixture and social media sensation.
