Ole Edward Watson, 25, vanished during a halibut trip near Cape Uganik, Alaska, on a summer day in 1977. Described as a Caucasian male with blond hair and blue eyes, about 6 feet tall and 135 pounds, he was wearing blue Levis, green foul weather pants over a wool plaid shirt and rubber boots when he fell overboard.

Two companions witnessed the fall and threw flotation devices, but Mr. Watson did not reach for them. The Alaska State Troopers investigated, but no body was recovered and the circumstances of his failure to seek the life-saving gear remain unexplained. The disappearance left family and investigators with unanswered questions about what happened in those cold waters.

Did anyone who fished or lived around Cape Uganik in 1977 remember the trip or have information about Ole Watson’s last hours?
