The former student of a Christian grade school in Nashville who killed three 9-year-olds and three adults in a shooting spree there was under a doctor's care for an "emotional disorder" and had amassed a collection of guns, the city's police chief said on Tuesday.
New details about assailant Audrey Elizabeth Hale, 28, emerged hours after police released harrowing video showing officers storming the Covenant School in the midst of Monday's rampage and conducting a room-to-room search before confronting and fatally shooting Hale.
