Kenyon R. Stapley, 59, was last seen in Glen Ellyn, Illinois, on August 16, 1993. He had plans that evening to dine with his fiancée to celebrate his upcoming 60th birthday but never showed up. A missing person report was filed on August 17 and deputies found his home locked with no signs of a struggle or forced entry.

Inside the house were Stapley’s wallet, identification, keys, and car — all left behind, which family described as highly unusual. The last known person to see him was a bank employee who had come to give a second mortgage estimate. His children said he had no known personal or financial problems and was in good spirits, looking forward to a September wedding.

There are no public details that explain his disappearance; investigators have considered voluntary departure, accident, or other possibilities. Does anyone who knew Kenyon or who lived in Glen Ellyn in 1993 have information that could help this long-open case?
