Luigi Mangione faces charges for the premeditated murder of Brian Thompson, CEO of UnitedHealthcare, in a case involving first-degree murder and acts of terrorism. The Manhattan District Attorney's Office, in collaboration with the NYPD and other agencies, led the investigation. The charges include one count of first-degree murder, two counts of second-degree murder, and additional weapons charges. The maximum penalty for these crimes is life without parole. The incident occurred on December 4, when Mangione allegedly used a 3D-printed gun to shoot Thompson in Midtown Manhattan. Mangione was later apprehended in Altoona, Pennsylvania, with a handgun in his possession.
