Luigi Mangione was detained after a worker at the fast-food giant spotted him eating, thought he looked suspicious and called the authorities. 

According to NBC News, Mangione's bag contained a three-page manifesto allegedly speaking to his "motivation and mindset" behind the killing.

"We don't think there is any specific threats to other people mentioned in that document, but it does seem that he has some ill-will towards corporate America," chief of detectives Joe Kenny said in a press conference.

Mangione also was in possession of a 9mm "ghost gun" similar to that used to shoot Thompson, as well as multiple fake IDs, including a New Jersey ID he reportedly used to check into a hostel.

The NYPD did not have his name on their radar until he was apprehended in Altoona.

Kenny said Mangione was born and raised in Maryland.

According to Mangione's X account (formerly Twitter), he describes himself as a Hawaii resident with a bachelor's and master's degree in computer science from the University of Pennsylvania. 

Thompson was fatally shot outside the New York Hilton Midtown hotel on Dec. 4.

A hooded, masked suspect fled the scene on a bike, with police losing track of him in Central Park.
