Luigi Mangione hit with federal charges, making him eligible for death penalty in alleged killing of UnitedHealthcare CEO Brian Thompson

Accused killer Luigi Mangione has been hit with new federal murder and stalking charges in connection with the brazen public execution of UnitedHealthcare CEO Brian Thompson on the streets of New York City, which could place the 26-year-old murder suspect in line for the death penalty.

Federal authorities unsealed the complaint Thursday in the high-profile case, which will proceed in parallel with the New York case in which he’s facing 11-counts at the state level – including an “exceedingly rare” first-degree murder charge.

The federal complaint will see Mangione face charges including murder through the use of a firearm, two counts of stalking and one count of possession of a firearm, court documents reveal.

Federal prosecutors pursued their own case to ensure the alleged gunman will be eligible for the death penalty, sources told The Post.

New York did away with the death penalty in 2004, but federal authorities maintain the ability to ask juries to impose capital punishment in certain murder cases.
