Motive, Evidence Detailed in CEO Assassination Case

Court documents and prosecutors state that Luigi Mangione meticulously planned the assassination of UnitedHealthcare CEO Brian Thompson, documenting his motives in a red notebook recovered at his arrest. Diary entries from August 2024 reveal Mangione’s intent to target the health insurance industry, describing it as a 'deadly, greed-fueled cartel.' He rejected indiscriminate violence, referencing the Unabomber as a cautionary example, and opted for a targeted attack to avoid harming innocents. Evidence includes Mangione’s writings, shell casings inscribed with phrases like 'delay' and 'deny,' and a confession letter. The attack caused widespread fear among insurance employees, prompting UnitedHealthcare to bolster security and remove executive information from public view. Mangione faces state and federal charges, with prosecutors arguing his writings and actions demonstrate clear premeditation and intent to intimidate the industry.
