Luigi Mangione, the suspect accused of killing UnitedHealthcare CEO Brian Thompson, is facing four new federal charges, according to newly unsealed court documents.
Mangione was already facing state charges in New York and Pennsylvania, but the newly filed federal charge of murder with a firearm may allow authorities to seek the death penalty.
He also faces a federal firearms charge and two counts of stalking, according to an unsealed complaint obtained by Courthouse News Service.
Mangione is accused of shooting Thompson outside the New York Hilton Midtown, where the CEO was scheduled to address an annual investors meeting.
The killing drew national attention as authorities searched for the suspect for days before finding Mangione at a McDonald’s in Altoona, Pennsylvania.
Mangione was transported from Pennsylvania to New York on Thursday after he waived extradition.
Mayor Eric Adams (D) was seen escorting Mangione, along with a large group of armed law enforcement officers, as the suspect landed in New York City via helicopter.
The new federal complaint also provides new information about an alleged notebook Mangione possessed, stating that it “contained several handwritten pages that express hostility towards the health insurance industry and wealthy executives in particular.”
It allegedly contained an entry dated Oct. 22 — six weeks before the murder — in which the investor conference was described as a “true windfall” and Mangione expressed an intention to “wack” the CEO of an insurance company.
Karen Friedman Agnifilo, Mangione’s attorney, stated that they will 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 terrorist act. First-degree murder carries a maximum sentence of life in prison without parole.
The alleged murder was described in charging papers as an attempt to “intimidate or coerce” civilians in order to influence government policies and conduct.
According to Manhattan District Attorney Alvin Bragg (D), the 26-year-old’s alleged attack jeopardized the safety of both locals and tourists in one of New York City’s most “bustling areas.”
“This was a frightening, well-planned, targeted murder that was intended to cause shock and attention and intimidation,” according to him.
Agnifilo accused federal prosecutors of heaping unnecessary charges against 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 released.
Mangione is also facing charges in Pennsylvania, where police say he was arrested with a ghost gun, silencer, and writings expressing hostility toward corporate America on his person.
