Police said on Monday that they arrested Luigi Mangione, 26, on firearms charges after he was recognised by an employee at a McDonald's restaurant in Altoona, Pennsylvania, according to New York officials. He was carrying a weapon and "multiple fraudulent IDs", including a New Jersey ID that matched the identity the suspect used to check into a New York City hostel before the shooting. He also had a three-page handwritten manifesto that included grievances with the US healthcare system, a document that spoke to the suspect's "motivation and mindset", officials said. What do we know about his background? 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, Maryland, called the Gilman School, according to school officials. Mr Mangione was named as the valedictorian. "This is deeply distressing news on top of an already awful situation. Our hearts go out to everyone affected," the school wrote in an email. He 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 university at the same time as Mr Mangione described him as a "super normal" and "smart person". "I would never have expected this," the friend said. 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 has 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. How was he arrested? Authorities planned to interview Mr Mangione while he is being held in Pennsylvania. He was taken into custody at a McDonald's after an employee spotted him and alerted police. Mr Mangione was in possession of a so-called ghost gun, a largely untraceable firearm that can be assembled at home using kits, that was likely 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 include a US passport and a fraudulent New Jersey ID that was used to check into the New York City hostel, where the suspect was spotted before the shooting Police also say he was found with handwritten documents - also described as a "three-page manifesto". The documents showed that he seemed to have "ill will towards corporate America", officials said. Police 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 to today What do his social media profiles tell us? 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." Police say a document written by Luigi Mangione include specific threats to other people, "but it does seem he has some ill will towards corporate America".
