After being spotted in a Connecticut pawn shop early Sunday, Ann Pettway, suspected of kidnapping a baby in 1987 and raising the child as her own, turned herself into authorities. She has also committed a string of petty crimes and was recently on probation until police put out a warrant for her arrest. Carlina White, the 23-year-old woman who claims Pettway kidnapped her, said she always had a strong suspicion Pettway was not her real mother. In a highly publicized reunion last week, she met her biological mother. White's mother says she believes Pettway to be the phony nurse at Harlem Hospital who took her child.
