TULALIP – A resident building a motorcycle track in a wooded area discovered skeletal human remains Sunday.

Snohomish County Sheriff’s Office Major Crimes Unit detectives responded to a 9-1-1 call in the 7900 block of 31st Ave NE around 4 p.m. Sunday. Detectives believe the skeletal remains may be a missing man who disappeared from that area in 2018.

The death does not appear to be suspicious in nature, but detectives continue investigate.

Positive identification of the remains, as well as cause and manner of death, will be determined by the county medical examiner.
