why was brian thompson killed

Brian Thompson, the CEO of UnitedHealthcare, was killed in a targeted shooting on December 4, 2024, in Midtown Manhattan. The killing was carried out by Luigi Mangione, who was arrested and charged with the murder. Mangione reportedly harbored deep resentment against the health insurance industry, which he perceived as parasitic and emblematic of corporate greed. This anger was partly fueled by personal grievances, including a medical injury incident and ideological opposition to the practices of insurance companies, particularly regarding claim denials and coverage issues. Mangione’s actions have been described as a "symbolic takedown," targeting Thompson as a representative of the health insurance industry's perceived injustices. The shooter left messages on the ammunition referencing insurance industry tactics, and a handwritten letter criticizing the healthcare system was found in his possession. Thompson had also received death threats related to insurance coverage disputes before his death.
