Summary based on the NamUs case record (MP55753)
On June 21, 1991, a boating trip on the Copper River in Alaska turned to tragedy. Loren E. Kosa, a 62-year-old man, was one of six individuals on board a boat near Haley Creek when the vessel capsized. The powerful river waters presented an immediate and life-threatening situation for everyone on the craft. While three people managed to survive the harrowing ordeal, Loren Kosa, along with Monte Kosa and Harry Rocheleau, disappeared into the turbulent river.
An immediate search and rescue effort was launched by the Alaska State Troopers, but the vast and rugged wilderness surrounding the Copper River presented significant challenges.
The circumstances of the boat capsizing point to a sudden and catastrophic event that left little time for those on board to react. The force of the river, combined with the likely cold temperature of the water, would have created a perilous environment. For the three who survived, it was undoubtedly a traumatic experience, having witnessed their companions swept away by the current. The initial report to the Alaska State Troopers on the same day as the incident underscores the urgency of the situation and the immediate concern for the three missing men.
Despite the efforts of authorities, no trace of Loren Kosa, Monte Kosa, or Harry Rocheleau was ever found. The case remains a painful memory for the families and the community, a stark reminder of the unforgiving nature of the Alaskan wilderness and the inherent dangers of river travel in the region. The official investigation, handled by the Alaska State Troopers, recorded the incident and the disappearances, but with no individuals recovered, the case transitioned from a rescue to a recovery mission, and eventually to an unsolved missing persons case. The disappearance of the three men is a somber event in the history of the Copper River area, illustrating a tragic accident that resulted in a profound and lasting loss.Last Seen: Jun 21, 1991
