An Ooltewah man who shot and killed what he thought was a middle-of-the-night prowler -- actually a 72-year-old man with advanced Alzheimer's disease -- Wednesday in Walker County, Ga., hasn't been charged but he might be later, authorities said.

The slain man, Ronald Westbrook, had walked about 3 miles to the shooting scene from his home on Carlock Circle, Sheriff Steve Wilson said at a Wednesday afternoon news conference. When Westbrook was shot, he was clutching letters he had taken from a mailbox on Marbletop Road, where he had lived previously, the sheriff said.
