Luigi Mangione was arrested Monday at a McDonald's in Altoona, Pennsylvania, for the murder of UnitedHealthcare CEO Brian Thompson. Patrons identified Mangione as the suspect in a manhunt while he was seated with a laptop and backpack. Police apprehended him after he provided a fake ID but later admitted his identity. Officers found a 3D-printed pistol, silencer, and manifesto criticizing corporate greed. New York prosecutors charged Mangione with murder, weapons possession, and using a forged document. He is fighting extradition to New York.
