Morris Werenko, 37, was last seen on August 31, 1989, in the Sault Ste. Marie, Ontario area. He is described as 71 inches tall with brown hair. Werenko and another man, Michael Gadke, were reportedly last heard from while in a Cessna C-172 circling over Goulais Bay. The aircraft was described as a red fuselage with a white stripe, white wings with red tips, a white underside and a red top engine cowling.

Searches were conducted in the days after they were last heard from, but no wreckage, debris, the aircraft or the men have been publicly reported found. The Sault Ste. Marie Ontario Provincial Police are listed as leading the investigation into the disappearance. Few concrete leads have been made public, and the case remains unresolved.
