(Troutdale, OR) -- A man who was found dead on top of shopping carts in the Troutdale Home Depot parking lot on Saturday died from natural causes. The Multnomah County Sheriff's Office says 61-year-old David Strickler was homeless. People put him on a sheet of plywood on top of two shopping carts, so they could push him to Mount Hood Medical Center, which is nearby, for help. He died before they could get him there. Investigators say there was no crime involved with his death.
