Luigi Mangione, 28, admitted in court that he fatally shot health insurance executive Brian Thompson outside a hotel in Manhattan on December 4, 2024, and pleaded guilty to two federal charges of stalking with the intent to kill. Mangione's plea will avert a federal trial, but there is no guarantee of leniency at sentencing, with prosecutors seeking life in prison, the maximum allowable sentence. Mangione spoke critically of the US health insurance system during his courtroom statement. The case was widely followed due to its brazen nature and the victim's high-profile status as CEO of UnitedHealthcare.
