NEW YORK (AP) — Police arrested a suspect Monday in the brazen Manhattan killing of UnitedHealthcare's CEO after a quick-thinking McDonald’s employee in Pennsylvania alerted authorities to a customer who was found with a weapon, mask and writings linking him to the ambush.
The chance sighting at the restaurant in Altoona led to a dramatic break in a challenging but fast-moving investigation that had captivated the public in the five days since the shooting that shook the health insurance industry.
The suspect, identified by police as 26-year-old Luigi Nicholas Mangione, had a gun believed to be the one used in last Wednesday’s shooting of Brian Thompson, as well as writings suggesting anger with corporate America, police said.
Video posted on the social platform X showed him being led into the Blair County Courthouse for his first appearance. Mangione has been charged with weapons offenses, forgery and other offenses and will be extradited to New York to face charges in connection with Thompson’s death.
He began shaking when police asked if he had been in New York City recently, court papers say.
Mangione was taken into custody about 9:15 a.m. after police got a tip that he was eating at a McDonald’s in Altoona, Pennsylvania, police said.
"He is believed to be our person of interest in the brazen, targeted murder of Brian Thompson,” NYPD Commissioner Jessica Tisch said.
Mangione had clothing and a mask similar to those worn by the shooter and a fraudulent New Jersey ID matching one the suspect used to check into a New York City hostel before the shooting, Tisch said.
A product of an elite education
NYPD Chief of Detectives Joseph Kenny said Mangione was born and raised in Maryland, has ties to San Francisco and a last known address in Honolulu, Hawaii. A message left Monday with a Philadelphia-area phone number connected to Mangione was not immediately returned.
But KYW Newsradio has confirmed that Mangione was a student at the University of Pennsylvania, majoring in computer science, from 2016 to 2020, when he graduated with both a bachelor’s degree and a master’s degree in engineering, according to a University spokesperson.
On his profile on LinkedIn, Mangione notes he was a teaching assistant at Penn in 2018 and 2019. Online records suggest he also founded a club for students interested in game development, called Upgrade, and his senior year project involved creating a scenic route-generation app.
As a student, he interned at a Maryland company famous for creating computer strategy games.
Since graduating, Mangione has worked at the online auto retailer TrueCar as a data engineer, according to his LinkedIn.
Before he went to Penn, he graduated as valedictorian from the prestigious Gilman School in Baltimore. In his graduation speech, he talked about his classmates’ “incredible courage to explore the unknown and try new things.”
Tuition at the private, all-boys day school is more than $37,000 annually.
Police found a three-page document with writings suggesting that Mangione had “ill will toward corporate America,” Kenny said.
The handwritten document “speaks to both his motivation and mindset,” Tisch said.
Mangione had a ghost gun, a type of weapon that can be assembled at home from parts without a serial number, making them difficult to trace, investigators said.
“As of right now the information we’re getting from Altoona is that the gun appears to be a ghost gun that may have been made on a 3D printer, capable of firing a 9 mm round,” Kenny said.
Officers questioned Mangione, who was acting suspiciously and carrying multiple fraudulent IDs, as well as a U.S. passport, Tisch said. Officers found a suppressor, “both consistent with the weapon used in the murder,” the commissioner said.
NYPD detectives and staff from the Manhattan district attorney’s office traveled to Altoona to interview Mangione, Kenny said.
A 'brazen, targeted' attack
Thompson, 50, was killed last Wednesday as he walked alone to a hotel, where UnitedHealthcare’s parent company, UnitedHealth Group, was holding its annual investor conference, police said.
The shooter appeared to be “lying in wait for several minutes” before approaching the executive from behind and opening fire, police said. He used a 9 mm pistol that police said resembled the guns farmers use to put down animals without causing a loud noise.
In the days since the shooting, police turned to the public for help by releasing a collection of nine photos and video — including footage of the attack, as well as images of the suspect at a Starbucks beforehand.
On Monday, police credited news outlets for disseminating the images and the tipster for recognizing the suspect and calling authorities.
“Luckily, a citizen in Pennsylvania recognized the subject and called local members of the Altoona Police Department responded to the call, and based on their investigation, they notified the NYPD,” Kenny said.
Photos taken in the lobby of a hostel on Manhattan’s Upper West Side showed the suspect grinning after removing his mask, police said.
Investigators earlier suggested the gunman may have been a disgruntled employee or client of the insurer. Ammunition found near Thompson’s body bore the words “delay,” “deny” and “depose,” mimicking a phrase used by insurance industry critics.
The gunman concealed his identity with a mask during the shooting yet left a trail of evidence, including a backpack he ditched in Central Park, a cellphone found in a pedestrian plaza and a water bottle and protein bar wrapper that police say he bought at Starbucks minutes before the attack.
On Friday, police found the backpack that they say the killer discarded as he fled from the crime scene to an uptown bus station, where they believe he left the city.
Retracing the gunman’s steps using surveillance video, investigators say the shooter fled into Central Park on a bicycle, emerged from the park without his backpack and then ditched the bicycle.
He then walked a couple blocks and got into a taxi, arriving at at the George Washington Bridge Bus Station, which is near the northern tip of Manhattan and offers commuter service to New Jersey and Greyhound routes to Philadelphia, Boston and Washington, Kenny said.
The FBI announced late Friday that it was offering a $50,000 reward for information leading to an arrest and conviction, adding to a reward of up to $10,000 that the NYPD offered.
