Permon Eugene Gene Gilbert, 46, of Bethel, Ohio, was murdered in May 1982. He was last seen alive on May 22, 1982, after a service repair call in Maysville, Ohio. His family reported him missing the next morning. On May 23 his beaten, shot, and nude body was found in a ditch on Swope Road in Clermont County, a few miles from his home. His van was recovered several days later on Ebeneezer Road in Adams County, more than 20 miles from his home.

Gilbert was a business owner and father of four. Personal items including his clothing, boots, cowboy hat, and Masonic items were missing and have never been recovered. The case drew national attention when it was featured on Unsolved Mysteries in 1989; later testing on materials from the investigation and renewed outreach through social media were tried but did not produce new leads. No arrests have been announced and the investigation remains open.

If anyone knew Permon Gilbert, saw his van around May 22–23, 1982, or has information about the missing items, please share what is known with investigators.
