Luigi Mangione shot Brian Thompson, the CEO of UnitedHealthcare. The shooting was a targeted act reportedly motivated by Mangione's ideological disdain for the health care industry and corporate America. Mangione allegedly saw Thompson as a symbolic representative of corporate greed and the health insurance sector's perceived corruption. Mangione approached Thompson from behind outside a Midtown Manhattan hotel and shot him with a 3D-printed handgun fitted with a suppressor. Police found a handwritten manifesto on Mangione expressing frustration and ill will toward corporate America, which helped clarify his motive as a symbolic takedown of health insurance corporations. Mangione was arrested days later in Pennsylvania with fake IDs and a weapon matching the murder gun. The case revealed that Mangione acted independently and was self-financed, driven by resentment of the health care industry and its executives.
