The suspect in the UnitedHealthcare CEO shooting called the Unabomber an “extreme political revolutionary,” according to a Goodreads review he left of Ted Kaczynski’s manifesto.

New York officials on Monday identified 26-year-old Luigi Mangione, 26, as the person of interest, five days after UnitedHealthcare CEO Brian Thompson was fatally shot last week outside a Hilton hotel in midtown Manhattan.

Mangione was arrested at a McDonald’s in Altoona, Pennsylvania, a city about 275 miles from New York City, using a fake New Jersey ID that matched the ID the suspect used to check into a hostel days before the shooting, said NYPD Commissioner Jessica Tisch at a press conference on Monday. Mangione has not yet been charged in Thompson’s death.

A Goodreads profile of Mangione revealed that he had reviewed Kaczynski’s infamous manifesto “Industrial Society and Its Future” in January. Kaczynski, often referred to as the Unabomber, attacked academics, businesspeople and random civilians with homemade bombs for nearly 20 years, with the goal of bringing about the collapse of the modern social order. Kaczynski justified his actions in the 35,000-word manifesto jointly published by The New York Times And The Washington Post in 1995 amid the threat of continued violence.

“It is easy to quickly and thoughtlessly dismiss this as the manifesto of a madman in order to avoid confronting some of the unpleasant issues it identifies. But it is simply impossible to ignore how prescient many of his predictions about modern society have proven to be,” Mangione wrote on Goodreads.

“He was a violent individual – lawfully imprisoned – who mutilated innocent people. While these actions are more accurately characterized as those of a crazed idiot, they are more accurately viewed as those of an extreme political revolutionary.”

Personal information revealed about Mangione after he was identified Monday suggests similarities between his biography and that of Kaczynski. The Unabomber scored 167 on an IQ test as a boy and was accepted into Harvard at age 16. He then attended graduate school at the University of Michigan before becoming an assistant professor at the University of California, Berkeley. He was 25.

Mangione’s LinkedIn profile shows that the 26-year-old graduated at the top of his class from Gilman School, an all-boys day school in Baltimore that has a distinguished alumni network. Mangione completed his bachelor’s and master’s degrees in computer science from the University of Pennsylvania in 2020.

According to a blog post on the Penn Engineering Today website, Mangione co-founded the University of Pennsylvania Game Research and Development Environment during his freshman year.
