The suspect nabbed in the killing of UnitedHealthcare CEO Brian Thompson is an anti-capitalist Ivy League grad who liked online quotes from “Unabomber’’ Ted Kaczynski — and seethed in a manifesto, “These parasites simply had it coming,” law enforcement sources told The Post on Monday.
Tech whiz Luigi Mangione, 26, originally from Towson, Md., apparently hated the medical community because of how it treated his sick relative, sources said.
The suspect also may have held a grudge because of his own interactions with the industry, sources said — noting an X-ray photo on his X account showing four pins in a spine.
They included titles such as “Crooked: Outwitting the Back Pain Industry and Getting on the Road to Recovery’’ and “Why We Get Sick: The Hidden Epidemic at the Root of Most Chronic Disease ― and How to Fight It.’’
They were added to his virtual bookshelf between May 2022 and February 2023.
High school friends said they were shocked to learn that the onetime prep school valedictorian and stellar University of Penn graduate may have been struggling — and even more stunned to learn of his bust tied to the slay case.
He was “always doing the right thing,’’ a former classmate told Fox News Digital.
Mangione “always had a smile on his face. Never really got the vibes of him being socially awkward. So that’s why I’m really surprised.
In addition to his serious issues with the health care industry, Mangione subscribed to anti-capitalist and climate change causes, according to law enforcement sources, citing online activity gleaned by authorities.
He was valedictorian of his 2016 high school graduating class at the Gilman School in Baltimore, where he played soccer, according to online sites. High school tuition at the all-boys school is nearly $40,000 a year.
“We recently became aware that the person arrested in connection with the killing of the UnitedHealthcare CEO is a Gilman alumnus, Luigi Mangione, Class of 2016,’’ the school’s leader, Henry Smyth, wrote in a letter to the community and obtained by local TV 11.
“We do not have any information other than what is being reported in the news. This is deeply distressing news on top of an already awful situation. Our hearts go out to everyone affected.”
Mangione said at the time of graduation that he planned to seek a degree in artificial intelligence, focused on the areas of computer science and cognitive science, at the University of Pennsylvania, according to an interview with the Baltimore Fishbowl.
The tech hotshot graduated cum laude from the private Ivy League institution in Philadelphia with a bachelor of science in engineering, computer and information science in 2020, according to his LinkedIn profile.
