Paul Clinton Marstall, 64, disappeared during a rafting accident on the Klutina River about six miles west of Copper Center, Alaska. The incident occurred on June 24, 1992. Marstall went under in the river’s cold, swift currents while four others from the same group were recovered in good condition.

At the time he vanished he was reportedly wearing camo-colored neoprene hip waders, a yellow raincoat, and a blue float vest. He was a white male with brown hair and blue eyes, 6 feet 1 inch tall and about 180 pounds. An extensive search of the Klutina and surrounding terrain followed but turned up no trace, and the official search was eventually concluded. Authorities presumed he drowned based on the circumstances.

Anyone who was on the Klutina River that day or who has information about the June 24, 1992 outing is asked to come forward.
