Luigi Mangione, the suspect accused of murdering CEO Brian Thompson, was found with a notebook that allegedly details a plan resembling the shooting. The notebook describes a targeted and precise plan to kill a CEO at what Mangion called "the annual parasitic bean-counter convention." He emphasized that it was a "targeted, precise attack" that posed minimal risk to innocents. Evidence includes Mangione’s fingerprints on items at the crime scene. A handwritten note found during his arrest criticized the healthcare industry and denied accomplices. Mangione faces multiple charges, including murder, and refuses extradition to New York.
