Arvin Dale Mack, 28, vanished from his fishing vessel Lisa Ann in Canoe Bay, Alaska. On July 12, 1984 he worked aboard the boat; the next morning the crew found he was missing and a check of the vessel showed he was not on board. The small skiff remained tied to the boat, which rules out a simple departure by that means.

Arvin was an American Indian/Alaska Native male, 5 feet 7 inches, with black hair, brown eyes, a scar on his right hand and a tattoo on his left forearm. The Alaska State Troopers were notified on July 13, 1984 and an investigation was opened, but no witnesses or evidence pointing to what happened have been reported, and the case remains unresolved.

Did anyone who fished Canoe Bay in July 1984 or who knew Arvin work with have information that could help clarify his disappearance?
