Saturday afternoon a dog found what appeared to be a human leg and dragged it home.
The dog’s owner contacted police.
The Thurston County Sheriff’s Office and the Coroner’s Office confirmed it was a human leg.
A search of the immediate area did not turn up additional remains before nightfall.
On Sunday, detectives and search and rescue personnel began searching the area.
Approximately 30 volunteer search and rescuers assisted with ground searchers and search dog teams.
Around 1 p.m., a search dog team found more bones including a rib cage, pelvis, and a skull.
Brady said it was unknown if the remains are male or female.
The Thurston County Coroner collected the remains on Sunday.
An autopsy is expected on Monday.
