A recent medical examination has confirmed that Shane Tamura, the gunman responsible for a mass shooting at an office building in Midtown Manhattan that houses the NFL headquarters, had chronic traumatic encephalopathy (CTE). The medical examiner revealed that Tamura, who killed four individuals during the attack, had low-stage CTE, a brain disease often associated with repeated head trauma. Reports indicate that Tamura criticized the NFL for allegedly concealing the dangers of brain injuries in his final notes. This revelation has sparked discussions on the implications of CTE and its connection to violent behavior.
