A MIA Army veteran during the Vietnam War was believed to be alive and well in Laos, Vietnam.

76-year-old John H. Robertson, is believed to have been living in the remote Vietnamese village for the past 44-years after his helicopter was gunned down during a clandestine mission.

Sgt. Robertson story is covered in part of a new documentary titled "Unclaimed" by filmmaker Michael Jorgensen. He has been locked in a bamboo cage mid-1968 and tortured for a year until his release.

"The MIA story was pretty unbelievable, pretty grandiose," he told the Globe and Mail, "and I was very skeptical."

"The ghosts of 1968, the faces of the people I have lost have never left me," Tom Faunce, a fellow war veteran said during the documentary's trailer. "A wise man once said time heals all wounds. One thing that's for certain, that man never went to war."

Although in the beginning everyone involved in the project was suspicious however they began to slowly believe that the man was in fact Robertson.

"There's maybe a bit of a misconception; everybody assumes: 'Well, obviously, he wants to come back to North America,'" Jorgensen told the Globe and Mail. "But at this point he's happier being back there, taking care of his wife, to whom he feels an incredible amount of loyalty, and their kids."
