Detectives from the King County Sheriff’s Office continue to investigate what is believed to be human remains found on Wednesday evening near the 24900 block of Frager Road South in unincorporated Kent.

Detectives responded to a suspicious circumstance call after passersby spotted the remains at about 5 p.m. Wednesday along the road near the Green River, said Sgt. Stan Seo, spokesman for the Sheriff’s Office, in a Thursday phone interview.

“They found what appeared to be human remains,” Seo said. “We continue to investigate.”

The bones were turned over to the King County Medical Examiner’s Office to confirm whether they are human. Seo said it could take a day or two or possibly until next week before the medical examiner makes a ruling.

The remains were found in a vacant lot, about one-half mile south of the Old Fishing Hole Park and across from the Riverbend Golf Complex as well as the popular Green River Trail.

“I don’t know the condition of the remains,” Seo said when asked for more details about how long the bones might have been there.

A nearby neighbor contacted the Kent Reporter and noted that as many as 17 police vehicles were in the area on Wednesday evening and that police had taped off Frager Road as well as a portion of the wooded area near the river. He said he often takes walks with his wife and baby along the trail.

“Did they find a transient’s body or should I be more concerned?” he said.
