CEO shooting suspect Luigi Mangione expressed 'ill will toward corporate America,' NYPD says

Authorities have identified Luigi Mangione, 26, as a person of interest in the shooting of UnitedHealthcare CEO Brian Thompson in Midtown Manhattan last week.

Officials said Mangione was arrested on firearm charges in Altoona, a Pennsylvania city approximately 230 miles from the site of the attack.

Here’s what we know about the suspect:

Mangione is an Ivy League graduate

Mangione earned bachelor’s and master’s degrees in engineering from the University of Pennsylvania in 2020, according to a university spokesperson. While at Penn, he also studied computer science, mathematics and information science.

Before college, Mangione reportedly attended the Gilman School, an all-boys private school in Baltimore, Maryland, where he graduated as valedictorian in 2016, according to several reports at the time. A former classmate told The Baltimore Sun they were shocked to hear the news, saying, “I almost had a heart attack.”

The University of Pennsylvania declined to share further details, and Gilman School officials did not immediately respond to requests for comment.

Part of a prominent family

Luigi Mangione is related to a family that owns several country clubs, health care facilities and real estate companies in the Baltimore area, according to reports by CBS and other outlets.

Maryland state Delegate Nino Mangione, who said he is a cousin of Luigi, released a statement on Monday saying the family was "shocked and devastated by Luigi's arrest." He said the family couldn't comment further.

NYPD: Suspect expressed hostility toward corporate America

At a Monday press conference, NYPD officials said Mangione was born and raised in Maryland, had ties to San Francisco and most recently lived in Honolulu.

Police have confirmed that investigators recovered shell casings at the crime scene engraved with the words “Deny,” “Defend” and “Depose.” The phrases may reference a book critical of insurance companies, "Delay, Deny, Defend: Why Insurance Companies Don't Pay Claim and What You Can DoAbout It" by Jay M. Feinman.

When officers arrested Mangione, they found a written manifesto detailing his alleged motives and what officials described as “ill will toward corporate America,” officials said.

He has no prior arrest history in New York, authorities said.
