For at least one family, their loved one was just yards away and 12 feet deep in a lake where they skied, swam and ate for so many years.
Debbie McManamon has been haunted by the disappearance of hergrandfather, who vanished 44 years ago when she was just 13 years old.
When she heard about the two cars and six sets of remains recovered from the bottom of Foss Lake inOklahoma, she said she knew it was her grandfather.
Authorities have not yet processed DNA to make a positive match, but McManamon, 57, of Dill City, Okla., said the "puzzle fits together."
"They pretty well confirmed it," she said. "All the evidence, everything fits as far as the time, the vehicle, the people that were with him."
She heard about the cars from a friend who sent her a news story on Facebook.
"I went, 'Oh my goodness,'" McManamon told ABCNews.com. "I called my husband, he drove home and we drove up to the lake and everything started unfolding."
"I just walked down there and they stopped me and they just looked at me like, 'What do you need?'" she said. "And I said, 'I think that could be my grandfather's car. He's been missing since April 8, 1969.'"
