Luigi Mangione will appear in federal court on Friday afternoon to be arraigned on federal charges as the Department of Justice has indicated it will seek the death penalty after he allegedly assassinated UnitedHealthcare CEO Brian Thompson.

The Department of Justice obtained an indictment against Mangione in the Southern District of New York. Mangione was charged with stalking and murdering Thompson as well as using electronic communications, interstate travel and a firearm when he allegedly killed the healthcare insurance CEO on Dec. 4, 2024.

If the 26-year-old is convicted of murder through the use of a firearm, Mangione could face the death penalty, as federal prosecutors have indicated in court filings.

Former Assistant U.S. Attorney Neama Rahmani told Fox News Digital that the Department of Justice’s openness to using the death penalty indicates a stark difference from the Biden administration.

Thompson, who lived in Minnesota, was in New York City for a publicly announced shareholder conference. An earlier federal complaint alleges that Mangione traveled by bus from Atlanta to New York City and arrived at the Port Authority bus terminal in Manhattan on Nov. 24, 2024.

Mangione allegedly checked into a hostel under a fake New Jersey license under the name “Mark Rosario.” Prior to allegedly shooting Thompson, the University of Pennsylvania graduate was seen riding an electric bicycle to a spot near the New York Hilton Midtown hotel.

He was arrested at a McDonald’s in Pennsylvania, and prosecutors recovered a notebook full of writings which they say depicted a calculated assassination attempt, in addition to a “ghost gun.”

Mangione also faces charges in New York and Pennsylvania in addition to the federal charges. He has pleaded not guilty to all charges.
