Luigi Mangione, suspected UnitedHealthcare CEO killer, delivered valedictorian speech about ‘challenging the world’

The man suspected of murdering UnitedHealthcare CEO Brian Thompson in cold blood on a New York City sidewalk was valedictorian at his leafy Maryland prep school — and delivered a graduation speech talking about “challenging the world.”

Luigi Mangione, 26, commented during his 2016 remarks on how he and classmates at the Gilman School in Baltimore excelled at “coming up with new ideas” and pushing boundaries.

“Having great ideas, however, isn’t enough to innovate,” he said, adding that people need “incredible courage to explore the unknown and try new things.”

“Now we’re moving on … we’ll be exploring the unknown,” Mangioni said.

The Gilman School is an all-boys academy with annual tuition of nearly $40,000 per year.

Mangione went on to study at the University of Pennsylvania where the tech hotshot graduated cum laude with a Bachelor of Science in Engineering (BSE), Computer and Information Science in 2020, according to his LinkedIn profile.

He says on his LinkedIn that he currently works as a data engineer at a car company based in California.

The details emerged after cops arrested Mangione just after 9 a.m. Monday after receiving a tip that he was eating at a McDonald’s in Altoona, Pennsylvania.

The suspect was found with a ghost gun, mask and writings linking him to last week’s deadly ambush outside a Midtown, Manhattan hotel that sparked a massive days-long manhunt.

He is being held in Pennsylvania on gun charges while authorities continue to build their case against him in the slaying.

Mangione eventually will be extradited to New York to face charges in connection with Thompson’s death, cops said.

While the exact motive was still unclear, sources said the slaying is believed to be tied to the behemoth US healthcare industry’s treatment of a sick relative.
