Maine mass shooter had a brain injury. Experts say that doesn't explain his violence.
Brain injury experts are cautioning against drawing conclusions from newly released and limited information about evidence of a brain injury in an Army reservist who killed 18 people last year in Maine’s deadliest mass shooting. Boston University researchers who analyzed a sample of Robert Card’s brain tissue said Wednesday they found evidence of traumatic brain injury. The analysis, requested by the Maine medical examiner, found degeneration in the nerve fibers allowing communication between different areas of the brain, inflammation and small blood vessel injury, according to Dr. Ann McKee of the university’s Chronic Traumatic Encephalopathy (CTE) Center.
