A 20-year-old male went swimming with a group of co-workers. At some point the victim was unable to stay afloat and slipped under the water.
Two boaters kayaking down the river attempted to pull the victim up and out of the river but were unsuccessful due to the depth.
Eastside surface rescue recovered the victim from the water and CPR was initiated. The victim was transported to the hospital where he was pronounced dead.
The King County Sheriff’s Office Marine Unit is conducting the investigation.
