Manhattan Shooter Had CTE,Medical Examiner Confirms

The mass shooter who suspected he had CTE when he killed four people and himself in a Manhattan office building in July did actually have the degenerative brain disease, the New York City medical examiner said on Friday.

Shane Tamura, who was 27 and played football in high school, had “unambiguous diagnostic evidence” of low-stage chronic traumatic encephalopathy, the medical examiner found. The condition, which can only be diagnosed posthumously, is caused by repeated exposure to head trauma and is most commonly associated in the US with tackle football players,especially those who have reached the NFL.

The medical examiner “found unambiguous diagnostic evidence of Chronic Traumatic Encephalopathy, also known as CTE, in the brain tissue of the decedent,” the statement read. “The findings correspond with the classification of low-stage CTE, according to current consensus criteria.”
