She hasnt made contact with anyone, relatives or friends. Vinson pulled her car into A.O.

She has a history of leaving her children with sitters longer than the agreed-upon time, but in the past, she always has made contact with someone, Woods said. One time, when the oldest little girl wasnt quite a year old, she left with a truck driver that she knew, said her mother, Barbara Ashley, who was keeping the child at the time. She was gone about a week, and then she came back. Vinson is 5-foot-7 and weighs 121 pounds. She has a dark tan, blue eyes and blond hair.
