Luigi Mangione faces federal charges after extradition to New York

(CN) — Luigi Mangione, the 26-year-old man accused of murdering UnitedHealthcare CEO Brian Thompson in Manhattan on Dec. 4, was charged by federal prosecutors on Thursday just hours after being extradited to New York following a court hearing in Pennsylvania.

In the10-page complaint, filed Wednesday but unsealed Thursday in the Southern District of New York, prosecutors charged Mangione with one count of murder through use of a firearm, one count of firearms offense and two stalking charges.

Mangione already faces murder charges in New York state court, but the federal charge is the first to make him eligible for the death penalty. State prosecutors indicated that both cases will proceed in parallel.

Mangione made his initial appearance in federal court at about 3 p.m. on Thursday, sporting a black quarter-zip sweater over a white dress shirt and khakis. He was not handcuffed, but shackled at his ankles over a pair of white sneakers.

When he took his seat, Mangione had brief but seemingly lucid conversations with his attorneys, Karen Friedman Agnifilo and her husband Marc Agnifilo.

As U.S. Magistrate Judge Katharine Parker read through his charges, Mangione followed along with papers in his lap. He occasionally nodded along when Parker explained his rights.

“Do you understand what you’re being accused of?” Parker asked.

“Yes,” Mangione replied bluntly.

Mangione’s attorneys made no application for bail, but raised issue with the fact that he was being charged simultaneously in state and federal court for seemingly the same crime.

Karen Friedman Agnifilo called it a “highly unusual situation” and claimed that the details of the cases — murder following stalking in the federal case, and a murder as an act of terror in state court — seemed to clash.

“These seem like two different cases,” she argued. “Is there one case? Two cases? Two investigations? Is there a joint investigation?”

“In over three decades … frankly, I’ve never seen anything like what is happening here,” Karen Friedman Agnifilo added.

The judge didn’t require government attorneys to explain themselves on Thursday, as this was merely an initial appearance. The next hearing is set for mid-January 2025.

The federal complaint revealed new details about Mangione’s supposed planning of Thompson’s killing. Investigators described the contents of Mangione’s notebook, which included an entry from Aug. 15, 2024, that said “the details are finally coming together.”

An entry from Oct. 22, 2024, illustrated an intent to “wack” a health insurance CEO at an investor conference. That note was around six weeks before Thompson’s murder, which occurred the morning of UnitedHealthcare’s investor conference.

Just hours before the federal complaint was unsealed, Mangione was in a state court hearing in Pennsylvania, where he agreed to be extradited back to New York to face his state murder charges.

“Because of the defendant’s reversal today and decision to waive his preliminary hearing as well as his extradition, certainly we believe it’s in the interests of justice to turn him over to the New York City Police Department and Manhattan district attorney’s office, which we did,” Blair County District Attorney Peter Weeks told reporters after the hearing, according to the Associated Press.

“He is now in their custody,” Weeks continued. “He will go forth with New York to await trial or prosecution for his homicide and related charges in New York. We intend to keep our case active and we intend to essentially revisit the case when the defendant is available for prosecution in Blair County.”

Manhattan prosecutorscharged Mangione on Tuesday with murder charges as an act of terrorism for the killing that Manhattan District Attorney Alvin Bragg described as a “frightening, well-planned, targeted murder that was intended to cause shock and attention and intimidation.”

Mangione, a Maryland native and Ivy League graduate, was detained for weapons charges in Pennsylvania after he was arrested at an Altoona McDonald’s on Dec. 9 following Thompson’s murder, which took the internet by storm.

In New York State court, Mangione faces one count of first-degree murder in furtherance of terrorism, two counts of second-degree murder — one of which is charged as killing as an act of terrorism, criminal possession of a weapon and other crimes.

New York law stipulates that terrorism charges can be brought when a supposed crime is “intended to intimidate or coerce a civilian population, influence the policies of a unit of government by intimidation or coercion and affect the conduct of a unit of government by murder, assassination or kidnapping.”

At a news conference on Tuesday announcing the charges, Bragg elaborated on why he classified two of Mangione’s murder charges as acts of terror.

“In its most basic terms, this was a killing that was intended to invoke terror — and we’ve seen that reaction,” Bragg said, referencing the outpouring of online support for Mangione that followed a CCTV clip of the assassination going viral.

Mangione has been a polarizing figure since his identity was revealed; certain corners of the internet have celebrated him for his apparent motivations behind the killing.

According to several reports, Mangione’s online footprint showed disdain for the for-profit health care industry. Police found the words “deny,” “defend” and “depose” printed on shell casings near the site of the shooting, seemingly a reference to a rallying cry for detractors of the industry — “Delay, deny, defend” — which refers to insurers delaying payment on claims, denying claims and then defending their actions.

Prosecutors and law enforcement officials have decried the public support for Mangione. New York Police Department Commissioner Jessica Tisch on Tuesday chided other New Yorkers, who she said “ghoulishly plastered posters threatening other CEOs with an X over Mr. Thompson’s picture, as though he was some sort of sick trophy.”

“In the nearly two weeks since Mr. Thompson’s killing, we have seen a shocking and appalling celebration of cold blooded murder,” Tisch said Tuesday. “Social media has erupted with praise for this cowardly attack. … Let me say this plainly, there is no heroism in what Mangione did."

Bragg said that local authorities are responding to an increase in concerns from CEOs and corporations about the enthusiasm surrounding Thompson’s killing, implying a fear of copycat attacks.

“I just can’t wrap my head around the notion that someone is celebrating this,” Bragg said.

The husband-and-wife duo representing Mangione in New York are a pair of high-profile criminal attorneys operating out of the Manhattan-based firm Agnifilo Intrater LLP.

Karen Friedman Agnifilo was formerly a high-ranking deputy in the Manhattan district attorney’s office. Marc Agnifilo, who is currently representing hip-hop mogul Sean “Diddy” Combs in his federal sex trafficking case, was a former supervisor at the U.S. Attorney’s Office for the District of New Jersey.
