Authorities in New York City said Monday that police in Altoona, Pa. have arrested a "strong person of interest" in last week's fatal shooting of UnitedHealthcare CEO Brian Thompson in midtown Manhattan.

At a press conference, police identified the person of interest as 26-year-old Luigi Mangione, who was spotted at a McDonald's in Altoona and taken into custody by local police on gun charges. Mangione was found in possession of a ghost gun and suppressor consistent with the weapon seen in video footage of the crime, a fake New Jersey ID matching the one the suspect is believed to have used at a Manhattan hostel and clothing, including a mask, that match those worn by the suspect. Police also said Mangione was in possession of a handwritten document that speaks to his motivation and mindset.

Officers with the NYPD are traveling to Pennsylvania today to question Mangione.

Strong person of interest' Luigi Mangione taken into custody at Pennsylvania McDonald's. Here's what we know so far.

At a press conference Monday afternoon in Manhattan, New York Mayor Eric Adams, New York Police Commissioner Jessica Tisch and NYPD Chief of Detectives Joseph Kenny provided details about 26-year-old Luigi Mangione, who they described as a “strong person of interest” in last week's killing of UnitedHealthcare CEO Brian Thompson.

Mangione was detained by Altoona, Pa., police at a McDonald’s restaurant roughly 300 miles west of New York City at approximately 9:15 a.m. An employee at the fast food chain recognized Mangione from photos released by New York police and contacted local law enforcement, Tisch said. Kenny added later that Mangione "was sitting there eating" when police approached. They found several items that they believe link him with the fatal shooting in Manhattan, including a ghost gun consistent with the weapon seen in video footage of the crime, a silencer, a fake New Jersey ID that matched the one used when the suspect checked in to a Manhattan hostel, a U.S. passport with his real name, a handwritten document or manifesto that police say speaks to Mangione’s motivation and mindset, and clothing, including a mask, that match those worn by the suspect. Kelly said that, based on the document found in Mangione's possession, it appeared that he "has some ill will toward corporate America."

On Friday, after nearly two days of a frantic manhunt that played out on the streets of Manhattan, New York police said they believed that the suspect in the case fled the city by bus.
