UnitedHealthcare CEO killing: Man who had gun, fake ID, mask arrested in Pennsylvania

NEW YORK (WPIX) – A man in Pennsylvania has been arrested in connection with the fatal shooting of UnitedHealthcare CEO Brian Thompson, officials said Monday.

Luigi Mangione, 26, was identified as the New York Police Department’s person of interest in last week’s slaying, according to NYPD Commissioner Jessica Tisch. He was arrested in Altoona, Pennsylvania, on a firearms charge after he was recognized by an employee of a McDonald's.

The man had a fake New Jersey ID that was used at a hostel where the gunman was believed to have stayed before the shooting, according to officials. The man also had a handwritten three-page document with writings critical of corporate America with him, they said.

He was also carrying a "ghost gun" — which may have been made on a 3D printer — and a suppressor when he was arrested, officials said.

Mangione had no prior arrests that the NYPD was aware of, and the investigation indicated that the suspect acted alone, they said.

The suspect's arrest came shortly after dogs and divers returned Monday to New York’s Central Park while the dragnet for Thompson’s killer stretched into a sixth day.

Investigators have been combing the park since the Wednesday shooting and have been searching at least one of its ponds for three days looking for evidence that may have been thrown into it.

Thompson was arriving at an investors meeting at the New York Hilton Midtown hotel just before 7 a.m. when he was shot in the back and leg by a masked gunman, according to the NYPD.

He was rushed to a hospital where he was pronounced dead. The suspect was waiting for Thompson to arrive at the hotel, police said.

The shooter appeared to be “lying in wait for several minutes” before approaching the executive from behind and opening fire, Tisch said.

Bullet casings found at the scene had the words “deny,” “defend,” and “depose” written on them, sources previously told WPIX.

A backpack believed to belong to the suspect was found in Central Park on Friday, but the gun used in the shooting was not in it, sources said.

The gunman arrived in New York City on a bus that originated in Atlanta, sources said.

The suspect was believed to have fled the city by bus after the shooting, police said.

The FBI was offering up to $50,000 for information that would lead to an arrest in Thompson’s slaying. The NYPD was also offering a $10,000 reward.

Late Saturday, police released two additional photos of the suspect that appeared to be from a camera mounted inside a taxi. The first shows him outside the vehicle and the second shows him looking through the partition between the back seat and the front of the cab. In both, his face is partially obscured by a blue mask.

This is a developing story.
