Manhattan Shooter's Brain to be Tested for CTE | JQJO

The investigation into the Manhattan shooting by Shane Tamura, who killed four before taking his own life, is underway. Tamura, a former high school football player with a history of mental illness, left a note suggesting he suffered from Chronic Traumatic Encephalopathy (CTE) and held a grievance against the NFL. Determining if he had CTE requires a lengthy brain examination process, taking weeks. Experts caution against directly linking CTE to the shooting, emphasizing that many factors contribute to such violence, and CTE doesn't automatically cause violent acts. The New York City medical examiner will conduct the necessary brain tests.
