Ivy League Grad Luigi Mangione Charged with Murdering Health Care CEO Brian Thompson in N.Y.C.

Luigi Mangione has been charged with murder following UnitedHealthcare CEO Brian Thompson’s fatal shooting.

PEOPLE can confirm that Mangione, 26, has been charged with one count of murder, two counts of second-degree criminal possession of a weapon, one count of second-degree possession of a forged document, and one count of third-degree criminal possession of a firearm.

The charges come after he was arraigned on Monday, Dec. 9, in Hollidaysburg, Penn, on five counts, per court papers: one felony count of forgery, one felony count of carrying a firearm without a license, one misdemeanor count of tampering with records or identification, one misdemeanor count of possessing instruments of a crime and one misdemeanor count of false identification to law enforcement authorities.

Mangione was detained on Monday at a McDonald’s in Altoona, Pa., after a customer spotted him and notified an employee. The employee then called the police.

Officers discovered him in possession of a 9mm “ghost gun” similar to that used to shoot Thompson, multiple fake IDs, and a 3-page manifesto critical of the health insurance industry.

A criminal complaint obtained by PEOPLE alleges that he gave the responding officer a New Jersey driver’s license with a false name.

Whie another officer asked Mangione if he had been to New York recently, he allegedly “became quiet and started to shake,” per the complaint.

Mangione graduated from the private Gilman School in Baltimore in 2016 as the class valedictorian, PEOPLE can confirm.  He has a bachelor’s and master’s degree in computer science from the University of Pennsylvania and Honolulu was his last known address.

Thompson was shot in broad daylight at a New York Midtown Hilton hotel on Dec. 4 in what police called a “brazen, targeted attack.”

He allegedly fired at least three bullets at Thompson — who was at the hotel for an investors’ conference — hitting him from behind in the back and leg. Mangione allegedly then fled northbound on Sixth Avenue before getting on an electric Citi Bike and heading towards Central Park, NYPD officials said at a press conference.

“We are deeply saddened and shocked at the passing of our dear friend and colleague Brian Thompson, the CEO of UnitedHealthcare. Brian was a highly respected colleague and friend to all who worked with him,” UnitedHealthcare would later say in a statement.
