"Examining the Link Between Lewiston Mass Shooter's Brain and CTE"

Tissue samples from the brain of the Lewiston mass shooter, who killed 18 people in Maine, have been sent for testing for chronic traumatic encephalopathy (CTE). Robert Card, a US Army reservist and certified firearms instructor, had a history of military experience and had been ordered to undergo a psychiatric evaluation prior to the shooting. CTE is a neurological disorder caused by repeated blows to the head and can only be diagnosed after death. Results from the tests are expected in six to eight months.
