Donald Wayne Sharp, 18, disappeared from Shawnee State Park in West Portsmouth, Ohio, around early February 1976 while on a solo camping trip. A Newport, Kentucky resident with sandy brown hair and blue eyes, he was dropped off with the understanding someone would pick him up a few days later. When his brothers arrived at the agreed spot to collect him, Sharp was gone and a search turned up no sign of him.

He had a bookbag with a couple changes of clothes, writing materials, and a violin, belongings that prompted some to wonder whether he intended to travel rather than camp. Reports also note a history of depression. His mother filed a missing person’s report, park rangers were notified, and the Ohio Bureau of Criminal Investigation has kept the case open.

Does anyone who knew Donald, or who was in Shawnee State Park in February 1976, have information that could help explain what happened to him?
