A notebook recovered when accused killer Luigi Mangione was nabbed details his plan to kill UnitedHealthcare CEO Brian Thompson at the company’s investors’ meeting, which is described as a “bean counter” conference, two police sources told the Daily News. “He felt shooting a CEO was better than trying to set off a bomb because he didn’t want to hurt anyone he felt didn’t deserve it,” one of the sources said. It wasn’t clear if the notebook, first reported by CNN, mentions Thompson by name. “What do you do?” Mangione wrote in his notebook of his plan, according to the New York Times  “You wack the CEO at the annual parasitic bean-counter convention. It’s targeted, precise, and doesn’t risk innocents.” The spiral notebook also includes to-do lists of tasks to be completed in the lead up to the slay, as well as musings justifying his plans, CNN reported. In one passage, he writes about the Unabomber. Thompson, killed last Wednesday morning in Midtown, is not mentioned by name in Mangione’s short hand-written manifesto which was also recovered when the 26-year-old was arrested Monday in Altoona, Penn. The manifesto note references the notebook, according to The Times. Brian Thompson, CEO of UnitedHealth.

In the approximately 260-word note, Mangione made it clear he acted alone — and that while what he did “had to be done,” he’s sorry for the harm it caused. “Frankly, these parasites had it coming,” the sources said he wrote in the manifesto note.

It is still not yet clear if Mangione or anyone close to him was denied medical coverage. After Thompson was gunned down, police said, Mangione ran off, rode into Central Park on a bike, ditched it on the Upper West Side, then took a taxi to the Port Authority bus terminal near the George Washington Bridge and escaped from the city.
