Luigi Mangione, the man accused of killing UnitedHealthcare CEO Brian Thompson, has been charged with murder as an act of terrorism, Manhattan prosecutors announced Tuesday. The case, which has unsettled the healthcare industry and sparked nationwide discussions, marks a significant escalation as authorities build their case against the suspect.
Thompson, 50, was fatally shot Dec. 4 in midtown Manhattan while walking to a hotel hosting a UnitedHealthcare investor conference. Prosecutors allege Mangione, 26, carried out the attack to intimidate and send a message, using violence to highlight frustrations with the U.S. healthcare system.
Manhattan District Attorney Alvin Bragg called the act “a deliberate, targeted murder meant to shock and intimidate the public.” The DA’s office formally filed terrorism-related charges, a rare but significant application of New York’s post-9/11 law, which allows crimes to be prosecuted as terrorism when they intend to intimidate civilians or influence government conduct.
After a multi-day manhunt, Mangione was arrested Dec. 9 in Altoona, Pennsylvania, where authorities found him with the alleged murder weapon, fake IDs, and a passport. He currently faces forgery and firearms charges in Pennsylvania while fighting extradition to New York.
Prosecutors described Mangione’s motivations as deeply personal and tied to anger toward the U.S. health insurance system. A handwritten letter found on Mangione at the time of his arrest reportedly described health insurance companies as “parasitic” and criticized corporate greed.
Mangione, a former Ivy League graduate, had shared frustrations about his struggles with chronic back pain on social media, advising others to challenge doctors and insurance providers. His family reported him missing weeks before the attack, describing him as increasingly isolated.
Thompson’s death sent shockwaves through the healthcare industry and rattled corporate leadership. Social media users debated the killing, with some praising it as “retribution” against health insurance companies. Meanwhile, New York Police Commissioner Jessica Tisch condemned any attempt to justify the violence, calling it “vile and reckless.”
Brian Thompson, a father of two teenagers, worked at UnitedHealth Group for over two decades, rising to become CEO of the insurance arm in 2021. Raised on a farm in Iowa, Thompson was widely respected for his leadership and humility.
As the investigation continues, prosecutors are expected to focus on Mangione’s actions leading up to the attack and the broader implications for public safety and the healthcare industry.
