The #gunman, #RobertCard, was a #grenade instructor in the #ArmyReserve. In 2023, after 8 yrs of being exposed to thousands of skull-shaking blasts on the training range, he began hearing #voices & was stalked by #paranoid#delusions. He grew increasingly erratic & #violent in the months before the Oct rampage in #Lewiston, in which he killed 18 people & then himself.
