The New York Police Department identified as Luigi Mangione, 26, the suspect arrested this Monday (9) who may be the killer of UnitedHealthcare CEO Brian Thompson, who was shot to death last week.
Born in Towson, Maryland, but with his last known address being Honolulu, Hawaii, Mangione was identified and detained at a McDonald’s restaurant in Altoona, Pennsylvania.
Sources told NBC that he was carrying a fake New Jersey identification in the name “Marc Rosario.” That was the same name on the fake New Jersey ID of a man staying at a Manhattan hostel who police were looking for as a “person of interest” in Thompson’s murder.

According to the New York Post, the suspect is an anti-capitalist activist on the internet and used to quote terrorist Ted Kaczynski, known as the “Unabomber”.
The New York Times, meanwhile, points out that the suspect’s social media accounts and several other sites offered a glimpse into his interests, including curiosity about self-improvement, clean eating and criticism of contemporary technology.
He maintained an active online presence on gaming platforms such as Steam and co-founded UPGRADE, the first video game development club at the University of Pennsylvania, when he was a student.

On his Instagram page, he presents himself as a “truth seeker” and a “system breaker”. He also says he will take matters into his own hands while “the world turns a blind eye.” “Watch the consequences unfold,” he wrote.
His LinkedIn page indicates that Mangione has a bachelor’s degree in engineering, computer and information science, as well as a master’s degree in those fields from the University of Pennsylvania, as of 2020.
Before his time at Penn State, he graduated from the Gilman School in Baltimore, where he was valedictorian, according to his profile.

In the profile, he identifies himself as a data engineer for the company TrueCar, but this information has not yet been confirmed by the authorities.
He has not yet been charged with the murder, but was taken into custody on Monday morning for being in possession of a ghost gun (probably made in a 3D printer) that uses 9mm bullets, a silencer, a US passport and four fake identities, plus a written manifesto, sources said.
The manifesto consisted of two and a half pages that reflected quotes Mangione posted on his Goodreads account from the infamous “Unabomber” who terrorized the country for nearly two decades by planting deadly bombs before being arrested in 1996.

NYPD Chief of Detectives Joseph Kenny said the document found on the man showed “ill will toward corporate America,” but he did not elaborate on what it said. The document also criticizes healthcare companies for putting profits above caring for people, according to police sources.
According to sources, Mangione had a particularly personal reason for hating the medical community – the treatment of a sick relative. Online obituaries show he lost a grandmother in 2013 and a grandfather in 2017.
His LinkedIn page also shows that he previously worked at a nursing home for a few months in 2014, while he was still in high school.
