On June 21, 1991, 41-year-old Monte Loren Kosa was one of six people aboard a boat on the Copper River near Haley Creek in the Copper River Census Area of Alaska when the vessel capsized. Powerful currents and cold, fast water overturned the boat; three people survived, while Monte Kosa, Loren Kosa and Harry Rocheleau were swept away and never recovered.

Monte was described at the time as 69 inches tall, 180 pounds, with brown hair and blue eyes. The remote location and the river’s dangerous conditions hampered search and rescue efforts after the capsizing, and all three men remain officially listed as missing.

Does anyone have memories of search efforts on the Copper River in June 1991 or information that could help the families still looking for answers?
