Luigi Mangione's Notebook Contains A Killing To-Do List: Reports

MIDTOWN, NY — Police have the notebook of Luigi Mangione, the suspect charged with murdering UnitedHealthcare CEO Brian Thompson in Midtown last week, according to several reports.

According to a report from the New York Times, which cites two unnamed law enforcement officials, the notebook contains a passage about going to a "bean-counter" convention to take out an executive.

“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 of the passages in the notebook reads, the officials told the New York Times.

Thompson was shot in the back when walking into UnitedHealthcare's annual investor conference on Dec. 4 at 6:45 a.m., police said.

Police spent the next six days combing the city for evidence and releasing surveillance photos of the suspect.

Mangione was first taken in for questioning on Monday at a McDonald's in Altoona, Pennsylvania, where an employee recognized him from one of the surveillance photos.

During questioning, police discovered Mangione had a gun, a silencer, a fake ID that matched the one the suspect used to check into an Upper West Side hostel, and a handwritten manifesto with him, NYPD Commissioner Jessica Tisch said on Monday.

Later that night, Mangione was charged with murder.

The writing in the notebook, first reported by CNN, also contains to-do lists to facilitate a killing.

Along with the notebook, police also discovered a handwritten 262-word manifesto, which was first released in full by independent journalist Ken Klippenstien and then later verified by law enforcement officials, according to MSN.

"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," the reported manifesto reads.

CAD stands for computed-aided design.

"I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy," the manifesto continued.
