Martha Oelman, 47, was found murdered in her secluded Sugarcreek Township cabin on September 7, 1997. Friends who had gone to check on her after she failed to arrive at an event discovered her lying face down on the bed; authorities determined she had been killed about two days earlier. Her body was nude and had blunt force trauma to the back of the head. Investigators found no signs of forced entry, no weapon, and no evidence of sexual assault.

Martha lived alone on a large, wooded family property near the Little Miami River and was described as gentle, private, and devoted to preserving nature. Despite involvement by the Ohio Bureau of Criminal Investigation since 1999 and multiple leads and theories — including inquiries into possible connections to LGBTQ+ individuals, a hate crime, property disputes, or a stalker — the case remains unsolved. A reward has been offered for information leading to an arrest.

If anyone knew Martha, had dealings at that property, or has information about visitors to the cabin in early September 1997, please come forward.
