Bobby Dunbar was an American boy who disappeared at the age of four. After an eight-month nationwide search, investigators believed that they had found the child in Mississippi, in the hands of William Cantwell Walters of North Carolina. Dunbar’s parents claimed the boy as their missing son. However, both Walters and a woman named Julia Anderson insisted that the boy with him was Anderson’s son. Julia Anderson could not afford a lawyer. The boy lived out the remainder of his life as Bobby Dunbar. He had four children of his own and died in 1966. In 2004, DNA profiling established in retrospect that the boy was not related to the Dunbars. (Source)
