University of Pennsylvania Grad Luigi Mangione Identified as POI in Killing of UnitedHealthcare CEO Brian Thompson

Authorities have named Luigi Mangione, 26, as a person of interest in last week’s fatal shooting of United Healthcare CEO Brian Thompson in Manhattan.

Mangione was taken into custody at a McDonald’s in Altoona, Pennsylvania around 9 a.m. ET, officials said.

At a press conference this afternoon, New York City Commissioner Jessica Tisch said that an employee at the McDonald’s recognized Mangione and called local police.

Tisch said Mangione was in possession of multiple IDs, including a New Jersey ID that matched the one used by the “person of interest” to check into a hostel on New York City’s Upper Westside, and a firearm and a “suppressor” that matched the one used by Thompson’s killer.

Mangione was arrested on gun charges while police continue to investigate his connection to Thompson’s killing.

Tisch said Mangione was also in possession of a handwritten document — news reports called it a manifesto — that “speaks to his motivation and mindset.”

Joe Kenny, chief of detectives for the New York police department, said at the same news conference that the firearm in Mangione’s possession was a ghost gun made with a 3D printer that was capable of firing a 9-millimeter round.

Kenny said the handwritten document was in possession of the Altoona police, and he offered few details on its content. Kenny did say, though, that it is three pages long, and that “we don’t think there are any specific threats to other people mentioned in the document” and that Mangione seems to have “some ill will toward corporate America.”

According to Mangione’s social media, he currently lives in Philadelphia and grew up in Towson, Maryland.

He graduated from Gilman prep school in Baltimore in 2016 and then from the University of Pennsylvania, graduating Ivy League in 2020 with a Bachelor of Science in engineering, according to a statement shared by a University of Pennsylvania spokesman in The Philadelphia Inquirer.

He also graduated with a major in computer science and a minor in mathematics, as well as earning a Masters in Engineering at the same time, according to the newspaper.
