Valedictorian at his $37,000-a-year all-boys prep school. Founder of a gaming club and graduate at an Ivy League university. A rapidly ascending data engineer at TrueCar Inc.
Luigi Nicholas Mangione was all that. And now, he’s also been charged in New York with the murder of insurance executive Brian Thompson, a father of two gunned down last week in Midtown Manhattan. The 26-year-old was arrested in Altoona, Pennsylvania, on Monday after authorities were alerted to a “suspicious male” who looked like the person wanted for the Dec. 4 shooting.
The New York City Police Department is on alert for “a risk that a wide range of extremists may view Mangione as a martyr and an example to follow,” according to a law enforcement document reviewed by Bloomberg News. “Rhetoric may signal an elevated threat facing executives in the near-term.”
The murder has deeply divided the public, with some seeing it as an act of standing up against the perceived failures of the insurance industry. Others view it as evidence of a breakdown in law and order, scapegoating company executives for systemic inequities.
Mangione was found with a homemade gun and a hand-written manifesto described as critical of health-insurance companies and corporate greed.
‘Brutal Honesty’
“Frankly, these parasites simply had it coming,” Mangione wrote. He juxtaposed the high cost of U.S. health care with the country’s declining life expectancy rates. The suspect said that he acted alone and was self-funded, according to the person familiar with the matter. “Evidently I am the first to face it with such brutal honesty,” he wrote.
Mangione faces additional charges in Pennsylvania, including forgery, carrying a gun without a license and showing law enforcement false identification. Information on a lawyer for Mangione weren’t immediately available.
A survey of his online presence shows Mangione — who attended the University of Pennsylvania — praised the manifesto of another Ivy League graduate known for violent acts aimed at corporate targets, the Unabomber, calling his insights “prescient” on the book-review website Goodreads.
Mangione appears to have had a privileged upbringing in Maryland, the product of a wealthy family with various business interests. His mother is a travel agent, and he had ties across the country and the world, most recently living in Honolulu.
Class Valedictorian
He attended the prestigious Gilman School in Baltimore and graduated as valedictorian in 2016. In his valedictory address, Mangione highlighted his classmates’ innovative spirit.
“Having great ideas, however, isn’t enough,” he said. “The class of 2016’s inventiveness also stems from its incredible courage to explore the unknown and try new things.”
At the University of Pennsylvania, he earned both bachelor’s and master’s degrees in engineering, computer and information science in 2020. He also founded the university’s first video-game development club. “Our goal is to have fun and learn,” Mangione told The Daily Pennsylvanian.
The summer before he graduated, he worked as the head counselor and an artificial intelligence teaching assistant at Stanford University in Palo Alto, California, designing lesson plans and teaching high school students. The work involved supervising more than three dozen students, according to his LinkedIn account. He helped create an “inclusive, fun, and stimulating” community among the residential staff, he wrote.
He began working as a data engineer at TrueCar in November 2020, and garnered his first promotion less than a year later. By October 2022, he was a data engineer III, working across more than a dozen technologies on lease and loan payments, pricing data sources and performance tracking. (His employment with TrueCar ended in 2023, the company said. It declined to provide any additional information.)
McDonald’s Arrest
Mangione was taken into custody at a McDonald’s restaurant after an employee reported a resemblance to the suspect in the nationwide manhunt. He had what appeared to be a ghost gun, made using a 3D printer to circumvent any paperwork or legal details involved in purchasing a firearm. It fired the same type of bullet that killed Thompson, though ballistics testing was still pending, said Joseph Kenny, the chief of New York Police Department detectives.
Nino Mangione, a Maryland state delegate and relative of Luigi, said in a statement that the family was “shocked and devastated” by the arrest. “We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved,” the Mangione family said in a statement posted on Nino’s X account.
