On a summer day in June 1991, 69-year-old Harry Robert Rocheleau, also known as Bob Rocheleau, was one of six people aboard a boat on the Copper River near Haley Creek when the vessel capsized. Three people survived but Rocheleau and two others, Loren Kosa and Monte Kosa, disappeared into the river.

Rocheleau was reported wearing a blue t-shirt, light blue pants, and black rubber boots when the boat overturned. The Copper River’s remote, rugged landscape and powerful currents made search and rescue difficult; despite efforts by the Alaska State Troopers and other search parties, no sign of Rocheleau or the Kosa brothers was found in the immediate aftermath, and their whereabouts remain unresolved.

If anyone knew these men, was on the river that day, or has information about the capsizing near Haley Creek, please share what might help locate them or clarify what happened.
