Luigi Mangione, the 26-year-old suspect accused of fatally shooting UnitedHealthcare CEO Brian Thompson outside a Manhattan Hilton hotel last week, was arrested on Monday at a McDonald’s in Altoona, Pennsylvania.

Authorities were tipped off by a restaurant employee who recognized him from widely circulated surveillance images.

During the arrest, police discovered several key pieces of evidence tying Mangione to the murder. Among them was a fake New Jersey ID with the alias “Mark Rosario,” allegedly used to check into a New York City hostel prior to the shooting.

Additionally, Mangione was found in possession of a “ghost gun” equipped with a suppressor capable of firing 9mm rounds. Detectives are investigating whether this weapon matches the firearm used in the killing.

A three-page note, critical of corporate America, was also recovered.

The note may provide insight into Mangione’s motive, with references that echo the violent ideologies of the Unabomber manifesto, which Mangione reportedly reviewed and quoted in his online activity.

Mangione, born and raised in Towson, Maryland, graduated as valedictorian from the prestigious Gilman School in 2016 before pursuing higher education at the University of Pennsylvania, where he studied artificial intelligence.

He is also the cousin of Maryland State Delegate Nino Mangione, who represents District 42A.

Investigators have determined that Mangione most recently lived in Hawaii and had no prior arrest record.

The NYPD launched a nationwide manhunt for Thompson’s killer, releasing surveillance images of the suspect over the weekend. These images led to numerous tips, culminating in Mangione’s arrest. He is currently being held in Pennsylvania on firearms possession charges and is expected to be extradited to New York to face murder charges.

UnitedHealth issued a statement in response to the arrest, saying:

“Our hope is that today’s apprehension brings some relief to Brian’s family, friends, colleagues, and the many others affected by this unspeakable tragedy. We thank law enforcement and will continue to work with them on this investigation. We ask that everyone respect the family’s privacy as they mourn.”

The investigation remains active, with detectives working to establish further connections between Mangione and the murder. Police are also examining Mangione’s potential motives, which appear rooted in his disdain for corporate America, as outlined in the recovered manifesto. Mangione remains in custody as authorities prepare to formally charge him with Thompson’s murder.
