On June 21, 1991, a boat carrying six people capsized on the Copper River near Haley Creek, Alaska. The vessel was overcome by powerful river waters; three people survived, while Loren E. Kosa, 62, along with Monte Kosa and Harry Rocheleau were swept away and never recovered.

The Alaska State Troopers launched an immediate search and rescue effort the same day, but the vast, rugged wilderness and the river’s force made recovery impossible. With no traces found, the case shifted from rescue to recovery and remains an unresolved missing persons matter.

If anyone was on the Copper River that day or has information about travel, campsites, or sightings near Haley Creek around June 21, 1991, please share what is known.
