BELLBROOK, Ohio (AP) -- Ohio investigators are still hoping for a break in their effort to identify the killer of the gentle, nature-loving daughter of a corporate leader.

The Dayton Daily News reports (http://bit.ly/14yifvS ) that friends and family are still baffled by the shocking 1997 slaying of Martha Oelman (OHL'-man), age 47. She was beaten to death in a family cabin deep in a southwest Ohio woods. Oelman's father Robert Schantz Oelman had been chairman of the National Cash Register Co., formerly one of Dayton's leading companies.

At the time, Sugarcreek Township police said the cabin didn't appear to have been ransacked, nor were there indications of sexual assault. Authorities say she died of blunt force trauma to the back of her head.

The Ohio Bureau of Criminal Investigation is heading the continuing investigation.
