The boy was found unharmed about three miles away, and he has since been reunited with his mother, according to DeKalb County police.
Investigators, however, said the ordeal might have been avoided. The woman pulled up to the QuikTrip at the corner of Panola Road and Hillandale Drive just before 11:30 p.m., parked her vehicle and left it running while she went inside, DeKalb police spokesman Sgt. J.D. Spencer said.
