David Wayne Jennings was 38 when he was last seen at Blackstone Lake in Archipelago Township (Parry Sound area), Ontario, on June 13, 1991. He is described as about six feet tall, 145–146 pounds, with brown wavy hair, blue eyes, a mustache and a previously fractured left cheekbone that had been surgically wired. His date of birth is recorded as January 27, 1953.

The accounts do not state who, if anyone, was with him, whether a boat or fishing gear were involved, what personal items might have been recovered, or the scope and methods of any searches. Noted clothing that could aid recognition included a black shirt, worn blue jeans, size-nine running shoes and a shiny blue Bass Fishing jacket with an embroidered bass across the shoulders.

The case is sparsely documented in missing-person databases and was handled by the Ontario Provincial Police. What exactly happened on the water that day remains unclear. Does anyone have memories, photos, or information about Jennings, his trip to Blackstone Lake, or relevant sightings from June 1991?
