UnitedHealthcare Shooting Suspect’s Notebook Reveals His Reasoning

Luigi Mangione’s notebook details his rationale for allegedly killing UnitedHealthcare CEO Brian Thompson last week.

Police have recovered the notebook, which details Mangione’s thought process behind shooting Thompson on a midtown Manhattan street as he walked to an investor’s conference.

“What do you do? You wack the CEO at the annual parasitic bean-counter convention. It’s targeted, precise, and doesn’t risk innocents,” one passage in the notebook said, according to two law enforcement officials who spoke with The New York Times.

Mangione allegedly concluded that using a bomb targeting Thompson “could kill innocents” and that a shooting would be more precise. The notebook also included a list of tasks to be completed before the killing and justifications for it, CNN reported, citing sources close to the case.

The notebook contained writings about the Unabomber, Ted Kaczynski, who killed three people and injured 23 others in a mail bombing campaign from 1978 to 1995 in the name of fighting environmental destruction and technological advancement. Mangione had given Kaczynski’s book a nearly four-star review in his (now removed) Goodreads account, attacking the bomber’s methods but appreciating his perspective.

“When all other forms of communication fail, violence is necessary to survive. You may not like his methods, but to see things from his perspective, it’s not terrorism, it’s war and revolution,” Mangione’s review said. “Fossil fuel companies actively suppress anything that stands in their way and within a generation or two, it will begin costing human lives by greater and greater magnitudes until the earth is just a flaming ball orbiting third from the sun.”

In his alleged manifesto, revealed Tuesday, Mangione stated that he was working alone and that planning the shooting was “fairly trivial,” and referenced the spiral notebook.

“This was fairly trivial: some elementary social engineering, basic CAD, a lot of patience. The spiral notebook, if present, has some straggling notes and To Do lists that illuminate the gist of it. My tech is pretty locked down because I work in engineering so probably not much info there,” he wrote.

“It is not an issue of awareness at this point, but clearly power games at play. Evidently I am the first to face it with such brutal honesty,” Mangione’s manifesto concluded.
