Lawrence Sanger was 20 when he disappeared from the Lake Athabaska region on August 29, 1979. Official records place his last known location at Fond du Lac, from where he and another man, Thomas Lidguerre, left by boat aiming for Uranium City. Neither man ever reached their destination or was seen again.

Two days after they departed, a swamped boat was found near the Narrows and Popular Point on Lake Athabaska. A search of the area ran for more than a month, but searchers were unable to locate Sanger or Lidguerre and no confirmed trace of either man has been publicly reported. The records do not state whether investigators concluded the pair met with an accident on the lake, reached shore, or experienced some other circumstance.

Sanger was about 6 feet 2 inches, with black hair, brown eyes, described as of Aboriginal descent, and had a distinctive scar on the top of one hand. His disappearance remains an active missing-person case with the F Division RCMP Historical Case Unit. If anyone knew Lawrence, his travel plans, or saw the boat after August 29, 1979, what can be shared with investigators?
