Comanche County Sheriff's Department investigators have made their third search for additional human remains after the discovery of old bones in a rugged wilderness area north of Saddle Mountain.

The detectives searched Saturday morning as they work to identify the remains. Sheriff Kenny Stradley tells the Lawton Constitution two of his detectives are working with the state Medical Examiner's office and the Oklahoma Crime Scene Archaeology Recovery Group on the project.

A 55-year-old woman clearing tree limbs found a partial skull in June 2010. A second search last December turned up numerous bone fragments near where the skull was found.

Stradley says he's been told the bones might have been at that location for a decade. His office is analyzing details from area missing-person cases from the past 30 years.
