In 1912 while on a fishing trip with his family 4-year-old, Bobby Dunbar disappeared without a trace.  His disappearance was widely reported in the south and after months of searching people in Mississippi spotted a boy fitting Bobby's description. Could this really be the Dunbar's missing child or is there more to the story?
