"Link Between Traumatic Brain Injury and Maine's Deadliest Shooting Revealed"

A brain tissue analysis revealed significant evidence of traumatic brain injuries in Robert Card, the Army reservist who killed 18 people in Maine last year. The analysis showed degeneration in nerve fibers, inflammation, and small blood vessel injury. Card's family apologized for the attack, and a special commission is investigating the shootings and reviewing the police response. There were warnings about Card's deteriorating mental health before the shootings, and there are calls for changes to the state's gun laws in the wake of the tragedy.
