Lewis County sheriff's detectives are investigating the discovery of human skeletal remains found Thursday evening just off a highway near Morton.
The Sheriff's Office reported the gender and age of the victim as well as how long the person had been dead were not yet known. The remains will be sent to the King County Medical Examiner's Office for a forensic pathologist to examine them.
A man called 911 about 5:30 p.m. Thursday to report the remains. He had pulled off the road to take a break. When he got out of his car, he noticed the human skeletal remains off the side of the road, the Sheriff's Office reported.
The Sheriff's Office is not releasing the exact location of the discovery but noted the surrounding area is rural and wooded.
Detectives and members of Lewis County Search and Rescue will be in the area today to look for potential evidence.
