David James Allison, 36, disappeared from a boat trip on the Kahiltna River on August 15, 1992. The boat struck a rock about nine to ten miles upriver from the mouth of the Yetna River, and David was seen going into the cold, fast-flowing water near Skwentna. He was wearing a brown leather jacket, a wool shirt, blue jeans, green hip boots, a one-ounce gold necklace, and possibly a chain belt with a .38 caliber handgun.

An initial report was filed with the Alaska State Troopers on August 16, 1992, and a search was conducted, but David was never found. The remote location, glacial-fed currents, and clothing colors that blended with the surroundings are noted factors that hampered locating him. The official account is that he fell from the boat and was swept away, but no definitive trace has been recovered.

Did anyone in the Skwentna or Kahiltna River area around mid-August 1992 have information that could help close this case?
