The decomposed body of a homeless person was discovered Thursday afternoon under the Boulevard Road overpass over the Interstate 5 bike trail, near the interstate.

The Thurston County Sheriff’s Department recovered the body at about 12:30 p.m., said Lt. Chris Mealy, spokesman for the sheriff’s office. He said the age and sex of the person are unknown, because the body “has been there for quite some time.” The deceased person was in a sleeping bag.

He said police don’t suspect foul play, and the death appears natural. But he said police aren’t ruling anything out, and won’t be sure of a cause until there an autopsy has been done. The body was sent to the office of Thurston County Coroner Gary Warnock for examination.
