Henry Charles Koepke was 23 when he vanished from Pendleton, Oregon, on March 10, 1985. That evening he left home with a friend, told his mother he’d be back late and asked her to leave the night latch off. He never returned and his family never heard from him again.

Henry is described as blond, hazel-eyed, six feet one inch tall, with a scar on his abdomen. Early accounts say he and his friend, both scuba divers, flew in the friend’s airplane to Friday Harbor in the San Juan Islands and stayed overnight on the friend’s boat because it was late. What happened after that is unclear; conflicting stories have been reported over the years and none have been substantiated.

Family members pursued law enforcement, private investigators, lawyers and others in search of answers. His mother’s obituary said she never fully recovered from the heartbreak of his assumed death. Does anyone have memories or information about Henry, his travel to the San Juan Islands, or the friend he was with that night?
