Gunman who killed 18 in Maine shooting had brain injury, study shows

Brain tissue analysis showed degeneration in the nerve fibers that allow for communication between different areas of the brain

An army reservist who shot and killed 18 people in Maine last year had evidence of traumatic brain injuries, according to a brain tissue analysis by researchers from Boston University.

There was degeneration in the nerve fibers that allow for communication between different areas of the brain, inflammation and small blood vessel injury, according to Dr Ann McKee of Boston University’s Chronic Traumatic Encephalopathy (CTE) center. The analysis was released Wednesday by the family of the deceased gunman and military reservist, Robert Card.
