LITHONIA, Ga. (AP) — A man who allegedly exchanged gunfire with police at an Atlanta-area school didn't seem to have any friends and rarely talked about his family or past during the months he lived with a couple who serve as pastors at a small church. But Michael Brandon Hill was quiet and didn't display anger or violent tendencies, said Natasha Knotts, the woman who took him in after he started coming to the small church where her husband is pastor and she is an assistant pastor. No one was injured in Tuesday's standoff, bringing relief to parents who had feared the worst after reports of the gunfire began surfacing.
