(Sandy, OR) -- A helicopter pilot helped locate a river rescue victim on Wednesday. The Clackamas County Sheriff's Office responded to the Sandy River at Dodge Park where a teenager went under water. A helicopter pilot, who was in the area, heard about the search and flew over river spotting the victim in the water. The boy was pulled from the river and given live-saving measures before being taken to a hospital. His condition hasn't been released. The Sheriff's Office is urging swimmers to use caution, because the water is cold from mountain runoff.
