Tamura was targeting NFL headquarters: Investigators believe that he was trying to target the headquarters of the National Football League, but took the wrong elevator, Mayor Adams said. A rambling note found on his body suggested he had a grievance against the NFL over an unsubstantiated claim that he suffered from chronic traumatic encephalopathy.
