Audrii Cunningham was last seen near her home in Polk County, Texas, at 7:00 a.m. (local time) on Thursday.
She was supposed to take a bus, but authorities indicated that she did not get on it or show up at school that day. Don Steven McDougal, 42, was arrested Friday on suspicion of aggravated assault in an unrelated incident. Detectives believe his dark blue 2003 Chevrolet Suburban was involved in Audrii's disappearance and are calling for anyone who saw him on Thursday or Friday to report him.
