The 3D-printed gun found on the suspect in last week's killing of United Healthcare CEO Brian Thompson matches shell casings found at the site of the shooting, NYPD Commissioner Jessica Tisch said Wednesday.

Luigi Mangione was charged with murder last night in New York in the death of UnitedHealthcare CEO Brian Thompson, who was shot and killed in the city last Wednesday. Mangione was denied bail today in Pennsylvania and is fighting extradition to New York.
