Darold Allen Stryffeler, 20, went out alone on Hagg Lake in Gaston, Oregon, on July 19, 1986, at about 4:00 p.m. He lived on Northeast North Valley Road and is described as having black hair and blue eyes. That evening, around 9:15 p.m., his motorboat was found beached with the ignition off, the tape player still running after the cassette had played to the end, his wallet on the seat containing $100, and alcohol aboard — but Darold himself was missing.

An immediate search produced no sign of him. Investigators initially thought he may have drowned, noting he was a very poor swimmer and had been drinking, but his body never surfaced and by November of 1986 authorities said the chances he was in the lake were pretty slim. Family members say Darold had argued earlier with people on the shore upset about him throwing empty beer cans into the water; those people were interviewed and ultimately cleared. The investigation remains open.

Did anyone see Darold or the boat on Hagg Lake that afternoon or evening, or hear about the argument on the shore?
