Luigi Nicholas Mangione, the suspect in the fatal shooting of a healthcare executive in New York City, apparently was living a charmed life: the grandson of a wealthy real estate developer, valedictorian of his elite Baltimore prep school and with degrees from one of the nation's top private universities.
Friends at an exclusive co-living space at the edge of touristy Waikiki in Hawaii where the 26-year-old once lived widely considered him a “great guy,” and pictures on his social media accounts show a fit, smiling, handsome young man on beaches and at parties.
Now, investigators in New York and Pennsylvania are working to piece together why the man may have diverged from this path to make the violent and radical decision to gun down UnitedHealthcare CEO Brian Thompson in a brazen attack on a Manhattan street.
The killing sparked widespread discussions about corporate greed, unfairness in the medical insurance industry and even inspired folk-hero sentiment toward his killer.

But Pennsylvania Gov. Josh Shapiro sharply refuted that perception after Mangione's arrest on Monday when a customer at a McDonald's restaurant in Pennsylvania spotted him eating and noticed he resembled the shooting suspect in security-camera photos released by New York police.
“In some dark corners, this killer is being hailed as a hero. Hear me on this, he is no hero,” Shapiro said. “The real hero in this story is the person who called 911 at McDonald’s this morning.”
U.S. & World
The suspect's family and upbringing
The suspect comes from a prominent Maryland family. His grandfather, Nick Mangione, who died in 2008, was a successful real estate developer. One of his best-known projects was Turf Valley Resort, a sprawling luxury retreat and conference center outside Baltimore that he purchased in 1978.
The family also purchased Hayfields Country Club north of Baltimore in 1986. On Monday, Baltimore County police officers blocked off an entrance to the property, which public records link to the suspect's parents. Reporters and photographers gathered outside the entrance.
The father of 10 children, Nick Mangione prepared his five sons — including Luigi Mangione’s father, Louis Mangione — to help manage the family business, according to a 2003 Washington Post report. Nick Mangione had 37 grandchildren, including Luigi, according to the grandfather's obituary.
The suspect's grandparents donated to charities through the Mangione Family Foundation, according to a statement from Loyola University commemorating Nick Mangione’s wife’s death in 2023. They donated to various causes, including Catholic organizations, colleges and the arts.
One of the suspect’s cousins is Republican Maryland state legislator Nino Mangione, a spokesman for the lawmaker’s office confirmed.
“Our family is shocked and devastated by Luigi’s arrest,” the suspect's family said in a statement posted on social media by Nino Mangione. “We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved.”
The suspect's education and work history
Mangione, who was valedictorian of his elite Maryland prep school, earned undergraduate and graduate degrees in computer science in 2020 from the University of Pennsylvania, a university spokesman told The Associated Press.
He learned to code in high school and helped start a club at Penn for people interested in gaming and game design, according to a 2018 story in Penn Today, a campus publication.
His social media posts suggest he belonged to the fraternity Phi Kappa Psi. They also show him taking part in a 2019 program at Stanford University, and in photos with family and friends at the Jersey Shore and in Hawaii, San Diego, Puerto Rico, and other destinations.
The Gilman School, from which he graduated in 2016, is one of Baltimore’s elite prep schools. The children of some of the city’s wealthiest and most prominent residents, including Orioles legend Cal Ripken Jr., have attended the school. Its alumni include sportswriter Frank Deford and former Arizona Gov. Fife Symington.
In his valedictory speech, the suspect described his classmates’ “incredible courage to explore the unknown and try new things.”
He took a software programming internship after high school at Maryland-based video game studio Firaxis, where he fixed bugs on the hit strategy game Civilization 6, according to a LinkedIn profile. Firaxis' parent company, Take-Two Interactive, said it would not comment on former employees.
He more recently worked at the car-buying website TrueCar, but has not worked there since 2023, the head of the Santa Monica, California-based company confirmed to the AP.
Time in Hawaii and reports of back pain
From January to June 2022, the suspect lived at Surfbreak, a “co-living” space at the edge of touristy Waikiki in Honolulu.
Like other residents of the shared penthouse catering to remote workers, he underwent a background check, said Josiah Ryan, a spokesperson for owner and founder R.J. Martin.
“Luigi was just widely considered to be a great guy. There were no complaints,” Ryan said. “There was no sign that might point to these alleged crimes they’re saying he committed.”
At Surfbreak, Martin learned Mangione had severe back pain from childhood that interfered with many aspects of his life, including surfing, Ryan said.
“He went surfing with R.J. once but it didn’t work out because of his back,” Ryan said, but noted that the suspect and Martin often went together to a rock-climbing gym.
The suspect left Surfbreak to get surgery on the mainland, Ryan said, then later returned to Honolulu and rented an apartment. An image posted to a social media account linked to the suspect showed what appeared to be an X-ray of a metal rod and multiple screws inserted into someone's lower spine.
Martin stopped hearing from the suspect six months to a year ago.
An X account linked to the suspect includes recent posts about the negative impact of smartphones on children; healthy eating and exercise habits; psychological theories; and a quote from Indian philosopher Jiddu Krishnamurti about the dangers of becoming “well-adjusted to a profoundly sick society.”
Police report a darker turn
Mangione likely was motivated by his anger at what he called “parasitic” health insurance companies and a disdain for corporate greed, according to a law enforcement bulletin obtained by AP.
He wrote that the U.S. has the most expensive healthcare system in the world and that the profits of major corporations continue to rise while “our life expectancy” does not, according to the bulletin, based on a review of the suspect’s handwritten notes and social media posts.
He appeared to view the targeted killing of the UnitedHealthcare CEO as a symbolic takedown, asserting in his note that he is the “first to face it with such brutal honesty,” the bulletin said.
The suspect called “Unabomber” Ted Kaczynski a “political revolutionary” and may have found inspiration from the man who carried out a series of bombings while railing against modern society and technology, the document said.
