Mangione faces charges in New York and Pennsylvania

Mangione faces second-degree murder, possession of a loaded firearm, possession of a forged instrument and criminal possession of a weapon charges in New York, according to according to an online court docket.

The Manhattan District Attorney’s office confirmed the charges.

The forged instrument is the fake NJ driver’s license he allegedly used to check into the hostel on the Upper West Side.

Mangione remains in the custody of the Pennsylvania Department of Corrections pending his extradition to New York.

Mangione, 26, was initially identified as a “strong” person of interest in the shooting death after he was apprehended at the McDonald’s in Pennsylvania, New York City Mayor Eric Adams said during a press briefing in New York on Monday.

Mangione was eating at the McDonald’s Monday morning when an individual thought he looked suspiciously like the shooting suspect and alerted an employee, who called police, authorities said.

He was carrying a firearm and suppressor “both consistent with the weapon used in the murder,” NYPD Commissioner Jessica Tisch said during the press briefing earlier Monday. The gun “may have been made on a 3D printer,” police said.

He also had “multiple fraudulent IDs,” including a fake New Jersey ID matching the ID the suspect used to check into his New York City hostel before the shooting incident, Tisch said. He was carrying a U.S. passport that identified him as Luigi Mangione, police said.


Police also recovered clothing, including a mask consistent with those worn by the wanted individual, as well as a three-page “handwritten document that speaks to both his motivation and mindset,” she said.

He was in possession of a ghost gun capable of firing a 9mm round and will face gun charges in Altoona, NYPD Chief of Detectives Joseph Kenny told reporters during the briefing earlier Monday.

He has been charged in Pennsylvania with five crimes, including carrying a gun without a license, forgery, falsely identifying himself to authorities and possessing “instruments of crime,” according to a criminal complaint.

The charging document alleges that Mangione lied about his identity to police and carried the ghost gun without a license.

When Altoona police asked him if he had ever been to New York City, Mangione started shaking, according to the charging document. He didn’t answer the question directly, police said.

Police said they are working to develop a full sense of his timeline in Pennsylvania and how long he has been in Altoona.

The NYPD sent detectives to Altoona to interview him and are going through the recovered writings and his social media, police said.

“It does seem that he had some ill will toward corporate America,” Kenny said.

A Goodreads account that appears to belong to Mangione left a four-star review on Ted Kaczynski’s “Industrial Society and Its Future” -- more commonly known as the “Unabomber manifesto” -- and described Kaczynski as “a violent individual -- rightfully imprisoned -- who maimed innocent people. While these actions tend to be characterized as those of a crazy Luddite, however, they are more accurately seen as those of an extreme political revolutionary.”

A source confirmed to ABC News that the Goodreads account is part of the law enforcement investigation.

Mangione has ties to San Francisco and his last known address was in Honolulu, Kenny said. In November 2023, Mangione was arrested in Honolulu for trespassing in a Hawaii State Park, court records show. He pleaded no contest and was ordered to pay a $100 fine.

He has no prior arrest history in New York, Kenny said.

Mangione was born and raised in Maryland, Kenny said.

Following his arrest on Monday, the Mangione family released a statement saying, “Our family is shocked and devastated by Luigi’s arrest.”

“We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved,” Maryland Republican Delegate Nino Mangione, who represents parts of Baltimore County, wrote on X on behalf of the family.

Luigi is a 2016 graduate of the Gilman School, a private high school in Baltimore, where he was the valedictorian of his graduating class, according to the school’s website. The school said in a statement that Mangione’s “suspected involvement in this case is deeply distressing news on top of an already awful situation.”

“Our hearts go out to everyone affected. Here on campus, our focus will remain on caring for and educating our students,” the statement continued.

Mangione is a May 2020 graduate of the University of Pennsylvania, according to a school spokesperson. He studied computer science and earned bachelor’s and master’s degrees in engineering from the Ivy League institution.

Following his graduation, Mangione worked as a data engineer at online car marketplace TrueCar, Inc. beginning in November 2020, according to a LinkedIn account that appears to belong to Mangione.

A representative for TrueCar said that Mangione stopped working for TrueCar in 2023.

Minjun Kim, a classmate who graduated from Gilman with Mangione, told ABC News that “he is the last person I expected to be involved in something like this.”

“He was an incredibly intelligent, humble and kind person,” Kim said. “He seemed like a very bright guy with a bright future.”

About six months ago, Kim said he was notified by other classmates that Mangione’s family was “inquiring about his whereabouts.”

“I didn’t hear anything about him until today when all the news dropped,” Kim said. “It really sucks for his family, who must be going through it right now.”
