(Linn County, OR) -- Police are releasing the identity of a man who died while swimming at the base of Tamolitch Falls, also know as the Blue Pool. Authorities say 21-year-old Kenny Truong of Kansas was killed in the accident Friday. Witnesses say the Wichita State University student jumped into the water and struggled to swim. People tried to help him reach shore, but they were unsuccessful. The Linn County Sheriff's Office says while Blue Pool is beautiful, the water temperature is 37 degrees and can cause immediate shock. Cell coverage is weak in the area and it can take hours to reach a hospital.
