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 has been charged with multiple state and federal crimes, including second-degree murder and other charges such as stalking and criminal weapon possession. Initially, he faced charges of murder in furtherance of terrorism, but those terrorism-related charges were dismissed by a New York state judge in September 2025. Federal prosecutors are seeking the death penalty in his case. At the time of his arrest, Mangione had a handwritten note expressing strong anti-corporate and anti-healthcare industry sentiments, implying the killing was motivated by perceived injustices in the U.S. healthcare system. He has pleaded not guilty to all charges and remains in federal custody awaiting trial.
