Detectives finally discovered the fate of the family who vanished in their car almost 70 years ago on their way to find Christmas decorations in Oregon. The group of five went missing in December 1958 in a case that gripped America. Two of the children were found dead months after the disappearance, but the other members had not turned up. But now, parents Kenneth and Barbara, and daughter, Barbie Martin, have been identified from human remains found in the Columbia River, officials said.
