Investigation into Maine Shooter's Brain Raises Concerns over CTE and Army Blast Exposure

The brain of Robert Card, the gunman responsible for the mass shooting in Lewiston, Maine, is being sent to Boston's CTE Center to determine if he suffered any brain injury or trauma while serving in the Army Reserve. Card, who died of a self-inflicted gunshot wound, had exhibited erratic behavior and had been committed to a mental health facility prior to the shooting. The analysis of Card's brain is expected to shed light on the impact of repeated blasts experienced during his military training. Results from the examination may take six to eight months.
