Police have identified the remains found in a rural part of Kentucky earlier this year.
A hiker found the remains spread across a two acre site in Grayson County, near the Hardin County line.
The state medical examiner has identified them as those of Edna "Rea" Miller.
The Hardin County woman had been missing since 2001.
The News Enterprise reports no cause of death has been determined, but investigators say they believe they will eventually make an arrest in the case.
