luigi mangione what did he do

Luigi Mangione is an American man accused of killing Brian Thompson, the CEO of UnitedHealthcare, in New York City on December 4, 2024. Mangione was arrested five days after the shooting and faced multiple charges including murder, first-degree murder in furtherance of terrorism, criminal possession of a weapon, and stalking. However, in September 2025, a New York judge dismissed the terrorism-related murder charges, though Mangione still faces a second-degree murder charge among others. Prosecutors have sought the death penalty in the federal case, while the state charges do not include the death penalty. Mangione has been characterized as a polarizing figure, partly due to his criticism of the U.S. health insurance system and a note found on him expressing grievances against corporate greed in healthcare. He has pleaded not guilty to all charges.
