On August 2, 2017 at approximately 5:32PM OSP responded to the report of a missing swimmer at Walton Beach near Sauvie Island. Upon OSP’s arrival at approximately 5:40PM, we learned the missing swimmer was identified as 18 year old, Jonathan James WALKER from Portland who had not been seen for approximately 15 minutes. The investigation revealed that WALKER and a group of friends had been on a boat that was anchored approximately 30 feet off the shore. The group had jumped into the water and began to swim towards the shore when WALKER began to struggle. A Good Samaritan and one of WALKER’s fiends attempted to assist him but were unable to. OSP was assisted by Multnomah County, Clark County and the US Coast Guard who searched the area for WALKER without success. Additionally, Sauvie Island Fire and Rescue conducted a search along the shore without success. A dive team from Multnomah County responded and recovered WALKER. The investigation is ongoing and alcohol use is being considered as a possible factor.
