Who is Luigi Mangione: What we know about healthcare CEO shooting suspect

A profile is emerging of the man being questioned over last week’s fatal shooting of United Healthcare’s chief executive in New York City.

Police announced on Monday they had arrested Luigi Mangione, 26, on firearms charges after he was recognised by an employee at a McDonald’s in Altoona, Pennsylvania.

The Baltimore, Maryland, native had a three-page handwritten document that mentioned grievances with the US healthcare system and indicated the suspect’s “motivation and mindset”, officials said.

Here’s all that we’ve learned so far about the suspect.

Mr Mangione was born and raised in Maryland and has ties to San Francisco, California, according to New York Chief of Detectives Joseph Kenny.

He has no prior arrests in New York and his last previous address was in Honolulu, Hawaii, police said.

He attended a private, all-boys high school in Baltimore, called the Gilman School, according to school officials. Mr Mangione was named as the valedictorian, typically the student with the highest academic achievements in a class.

A former classmate, Freddie Leatherbury, told the Associated Press news agency that Mr Mangione came from a wealthy family, even by that private school’s standards.

“Quite honestly, he had everything going for him,” Mr Leatherbury said.

Mr Mangione is also a graduate of the University of Pennsylvania, where he received a bachelor’s and master’s degree in computer science, according to the school, and founded a video game development club.

A friend who attended the Ivy League college at the same time as Mr Mangione described him as a “super normal” and “smart person”.

Mr Mangione worked as a data engineer for TrueCar, a digital retailing website for new and used cars, according to his social media profiles. A company spokesman told the BBC he had not worked there since 2023.

According to the LinkedIn profile, Mr Mangione previously worked as a programming intern for Fixarixis, a video game developer.

Mr Mangione comes from a prominent family in the Baltimore area whose businesses include a country club and nursing homes, according to local media.

He is the cousin of Republican state lawmaker Nino Mangione, according to media reports.

Mr Mangione was taken into custody at a McDonald’s after an employee spotted him and alerted police.

He was in possession of a so-called ghost gun, a largely untraceable firearm that can be assembled at home using kits, and was probably manufactured on a 3D printer, according to police officials. He also had a suppressor.

Police said he was carrying several IDs, including one with his real identity and another that was fake. These IDs included a US passport and a fraudulent New Jersey ID that was used to check into the New York City hostel, where the suspect was seen before the shooting

Police say he was also found with three pages of handwritten documents in which he seemed to express “ill will towards corporate America”.

Investigators revealed that finding the 26-year-old was a complete surprise, and that they did not have his name on a list of suspects prior before Monday.

Social media profiles provide some possible clues about Mr Mangione’s thinking.

A person matching his name and photo had an account on Goodreads, a user-generated book review site, where he gave four stars to a text called Industrial Society and Its Future by Theodore Kaczynski – more popularly known as the Unabomber manifesto.

Starting in 1978, Kaczynski carried out a bombing campaign that killed three people and injured dozens of others, until he was arrested in 1996.

In his review, Mr Mangione wrote: “When all other forms of communication fail, violence is necessary to survive. You may not like his methods, but to see things from his perspective, it’s not terrorism, it’s war and revolution.

“‘Violence never solved anything’ is a statement uttered by cowards and predators.”
