What we know about the person of interest in the UHC shooting

The person being questioned in Pennsylvania in connection with the shooting death of United Healthcare CEO Brian Thompson has been identified as Luigi Mangione, according to six law enforcement officials with knowledge of the investigation.

Mangione, 26, was arrested on a firearms charge by police in Altoona, Pennsylvania, but has not been charged in the Thompson slaying, officials said Monday. 

Investigators are looking into whether Mangione had recently traveled to Altoona by bus from Philadelphia, some 240 miles away, one senior law enforcement official said.

Mangione was found in a McDonald’s restaurant carrying multiple fake IDs, including one with the name “Marc Rosario,” according to two senior law enforcement officials. He was recognized by an employee, who called local police, officials said at a news conference.

Police said last week that the suspected shooter arrived in New York City by bus in late November and had stayed at a Manhattan hostel.

The man who checked into the hostel also used a fake New Jersey ID with the same name, “Marc Rosario,” according to three sources familiar with the investigation.

Thompson, 50, was gunned down on the morning of Dec. 4 in front of the New York Hilton Midtown as he was on his way to speak at an investor conference. 

Police said the shooter appeared to wait for his intended target in what New York Police Commissioner Jessica Tisch described as a “premeditated, preplanned targeted attack.”

The masked shooter approached Thompson from behind and shot him at least once in the back and once in the right calf.  Shell casings found at the scene had the words “deny,” “delay” and “depose” written on them.

The gunman fled on foot, then on a bike into Central Park, according to police.
