Investigators still have no i.d. tied to the human remains found on the Warm Springs Indian Reservation on Tuesday, because medical exams indicate they may have been there for as long as ten years.  Warm Springs Tribal Police say a resident who was salvaging wood from an old wooden cattle chute along Tenino Road found what appeared to be a human skull – police say they found other bones near it.  Cadaver dogs have been brought in to continue searching the area.
