The man who opened fire and killed four people at the NFL's New York City office in July had "unambiguous diagnostic evidence" of low-stageCTE, the New York City Office of the Chief Medical Examiner said Friday. 

"Following a thorough assessment and extensive analysis by our neuropathology experts, OCME has found unambiguous diagnostic evidence of Chronic Traumatic Encephalopathy, also known as CTE, in the brain tissue of the decedent. The findings correspond with the classification of low-stage CTE, according to current consensus criteria," the medical examiner’s office said. 

"CTE may be found in the brains of decedents with a history of repeated exposure to head trauma. The science around this condition continues to evolve, and the physical and mental manifestations of CTE remain under study."

A medical examiner’s spokesperson said, "We’re unable — as I don’t think science would be able to at all at this point — to say what role CTE played in that particular incident, causing that incident," she said. 

"We’re not saying that CTE is the cause of what happened at the Park Avenue shooting."
