The alleged gunman died of a self-inflicted gunshot, the Georgia Bureau of Investigation said, according to WSB. Patrick Joseph White, 30, had letters that showed his “discontent” with COVID-19 vaccines.

Patrick White is believed to have struggled with his mental health, according to that information. As he grappled with those issues, sources said, White had become increasingly fixated on the COVID-19 vaccine as a source of his grievances.
