NYC NFL Headquarters Shooter Had CTE, Medical Examiner Finds

A man who killed four people in a Manhattan office building and suspected he had CTE was confirmed posthumously to have the degenerative brain disease, which is linked to repeated head trauma and often associated with football players, though he never played in the NFL. The shooter, Shane Tamura, blamed his mental health issues on football-related brain injuries and targeted NFL headquarters, resulting in four deaths. The case highlights ongoing concerns about the long-term effects of head trauma in athletes and others exposed to repeated brain injuries.
