BURSTLuigi Mangione, the suspect accused of killing UnitedHealthcare CEO Brian Thompson, faces four new federal charges, newly unsealed court documents show.
Mangione was already facing state charges in New York and Pennsylvania, but the newly filed federal charge of murder through use of a firearm could enable authorities to seek the death penalty.
He also faces a federal firearms charge and two counts of stalking, according to the unsealed complaint, which was posted by Courthouse News Service.
Mangione is accused of gunning down Thompson outside New York Hilton Midtown, where the CEO was set to address an annual investors meeting. The killing captivated nationwide attention as authorities for days searched for the suspect before locating Mangione at a McDonald’s in Altoona, Pa.
Mangione was transported from Pennsylvania to New York on Thursday after he waived his extradition. New York City Mayor Eric Adams (D) was seen escorting Mangione alongside a large group of armed law enforcement as the suspect landed in the city in a helicopter.
The new federal complaint also reveals new details about an alleged notebook Mangione possessed, saying it “contained several handwritten pages that express hostility towards the health insurance industry and wealthy executives in particular.”
It purportedly included an entry dated Oct. 22 — six weeks before the killing — in which the investor conference was described as a “true windfall” and Mangione described an intent to “wack” the CEO of an insurance company.
Karen Friedman Agnifilo, Mangione’s attorney, said they would fight the charges “in whatever court they are brought.”
Earlier this week, state prosecutors in Manhattan charged Mangione with 11 counts, including first-degree murder and second-degree murder as a crime of terrorism. The first-degree murder charge carries a sentence of up to life in prison without parole.
Charging papers cast the alleged murder as an attempt to “intimidate or coerce” civilians and influence the policies and conduct of the government.
Manhattan District Attorney Alvin Bragg (D) said the 26-year-old's alleged attack threatened the safety of local residents and tourists alike in one of the most “bustling parts” of New York City.
"This was a frightening, well-planned, targeted murder that was intended to cause shock and attention and intimidation,” he said.
Agnifilo accused federal prosecutors of heaping unnecessary charges on Mangione.
“The federal government's reported decision to pile on top of an already overcharged first-degree murder and state terror case is highly unusual and raises serious constitutional and statutory double jeopardy concerns,” she said before the charges were unsealed.
Mangione also faces charges in Pennsylvania, where police said he was captured with a ghost gun, silencer and writings expressing ill will toward corporate America on his person.
