On January 14, 2013, 18-year-old Joseph Arnold Deseranno of Milwaukie, Oregon, slipped while attempting to wade across the Sandy River near the former Marmot Dam and fell into very cold, fast-moving water. He was wearing hip waders and a dark camouflage jacket but no personal flotation device. A friend saw the fall and called 911; Clackamas County rescue crews and about 20 members of the Clackamas County Water Rescue Consortium searched for more than four hours that day and continued searches in the days that followed. Icy roads, 27-degree air and 35-degree water impeded efforts, and Joseph was not recovered.

Did anyone fish or travel that stretch of the Sandy River in January 2013 and recall seeing anything that could help explain what happened?
