Richard Gregory Rollo, 33, vanished from Muskrat Lake near Cobden, Ontario on August 3, 1997. Eyewitnesses reported he jumped from his boat near an area called Gull Rock and did not resurface; there was no sign of him in the water. He was described as a white male, about 71 inches tall, 190 pounds, with brown hair, blue eyes and a partial amputation of his right thumb. He was reportedly wearing a grey shirt, a sweater and blue shorts when last seen.

The Renfrew detachment of the Ontario Provincial Police took charge and searches focused on the area where he entered the water. The circumstances of why he jumped from the boat have not been publicly detailed. He is presumed to have drowned in Muskrat Lake, but with no recovery the case remains unresolved and the file is open.

Did anyone who knew Richard or who boated Muskrat Lake in August 1997 see anything that could help explain what happened?
