Federal prosecutors filed new charges against Luigi Mangione, the suspect in the fatal shooting of United Healthcare CEO Brian Thompson, on Thursday. The unsealed complaint revealed some of the writings that police allegedly found in Mangione's notebook when he was taken into custody.
In the complaint, the Department of Justice alleges Mangione kept a notebook in the months leading up to the fatal shooting, writing in an Aug. 15 entry that “the target is insurance.” Mangione allegedly wrote that an attack on an insurance company "checks every box."
