Luigi Mangione: Here's what we know so far about the UnitedHealthcare CEO shooting suspect

As details continue to emerge in the Wednesday killing of UnitedHealthcare CEO Brian Thompson, a profile of the suspected shooter arrested Monday is becoming clearer as well.
Luigi Mangione was arrested in Pennsylvania Monday on gun charges before later being charged with second-degree murder. He is expected to be extradited to New York for prosecution.
The 26-year-old, who comes from a wealthy and prominent Maryland family that sent him to prestigious schools, left writings that showed an "ill will toward corporate America," police allege, and reportedly saw the targeted killing of the CEO as a statement against those who he felt represented corporate greed.
"He appeared to view the targeted killing of the company’s highest-ranking representative as a symbolic takedown and a direct challenge to its alleged corruption and ‘power games,’ asserting in his note he is the ‘first to face it with such brutal honesty,’" an NYPD police report said, according to multiple outlets.
Here's what we know so far about Luigi Mangione.
Who was arrested in the shooting of UnitedHealthcare CEO Brian Thompson?
New York Police Commissioner Jessica Tisch announced Monday that an arrest related to the shooting had been made in Altoona, Pennsylvania. Luigi Mangione, 26, was arrested on weapons charges and was said to be in possession of a gun similar to the one used in the shooting.
Mangione was identified by a McDonald's customer who then reported their concerns to an employee. The worker called and told police that Mangione was "acting suspiciously" around 9:15 a.m. on Monday.
Initially after the arrest, New York City Mayor Eric Adams called him a "strong person of interest in the shooting that shook our city," but Mangione was not immediately charged with murder in Thompson's death until later Monday evening, when he was served with a second-degree murder charge.
An arrest warrant filed in New York City said police found writings that belonged to Mangione, including a written admission about the crime” and listed his charges as second-degree murder, two counts of criminal possession of a weapon in the second degree, criminal possession of a forged instrument and criminal possession of a weapon.
Who is Luigi Mangione and the Mangione family?
Mangione, 26, comes from a prominent Maryland family. He was born to parents Louis and Kathleen Zannino Mangione and grew up in the state.
As USA TODAY previously reported, his late grandfather, Nicholas Mangione Sr., developed real estate and owned country clubs, nursing homes, and a radio station, while his late grandmother, Mary Mangione, was a philanthropist who served as a trustee for the Baltimore Opera Company, on the county tourism board and with groups such as the American Citizens for Italian Matters. His mother owns a funeral home in the area.
His cousin, Nino Mangione, is a Republican member of the Maryland House of Delegates. Nino Mangione released a statement on Monday following the arrest.
"We only know what we have read in the media," the statement read. "Our family is shocked and devastated by Luigi’s arrest. We offer our prayers to the family of Brian Thompson and we ask people to pray for all involved."
Where did Mangione go to high school, college?
In 2016, Mangione graduated as valedictorian from Gilman School in Baltimore, a prestigious private high school where tuition can cost nearly $40,000 annually.
In 2019, he spent a summer as a counselor for a Stanford University pre-collegiate program.
In 2020, he graduate cum laude from the University of Pennsylvania with a combined Masters's and Bachelor's degree in computer engineering, according to his LinkedIn. He was also a member of the Phi Kappa Psi Fraternity.
After graduating, he moved to Honolulu, Hawaii, according to his LinkedIn, and took a job as a data engineer at the auto marketplace website TrueCar, Inc. TrueCar said in an email he has not been employed at the company since 2023.
What evidence did police find?
Police said Mangione was found to have several pieces of damning evidence that led to his arrest.
In searches of his possessions, police found a 3D-printed handgun and silencer, a mask, several fraudulent identifications and writings that officials say speak to his motivation.
NYPD Chief of Detectives Joseph Kenny said at a news conference that a three-page, handwritten document was found that expressed "ill will toward corporate America." The New York Times and CNN also reported, citing an internal NYPD report, that Mangione thought of himself as a martyr against "corporate greed" and the insurance industry.
“He appeared to view the targeted killing of the company’s highest-ranking representative as a symbolic takedown and a direct challenge to its alleged corruption and ‘power games,’ asserting in his note he is the ‘first to face it with such brutal honesty,’” said the NYPD report, according to multiple outlets.
Mangione also presented police in Pennsylvania with a forged New Jersey driver’s license, which matched the number on the license presented at a hostel in Manhattan where the suspect is believed to have stayed before the shooting, an arrest warrant states.
Mangione is expected to be extradited to New York City. It's unclear when that will happen. The Manhattan District Attorney's Office did not immediately return USA TODAY's request for comment. It was not immediately clear whether Mangione has an attorney who can comment on the allegations and charges against him.
