Mark Harris Bell was 41 when he vanished while working aboard the fishing vessel Arctic Trawler in Dutch Harbor, Alaska, on August 11, 1991. He was described as a Caucasian male, brown hair, blue eyes, five feet eleven inches tall and about 170 pounds.

He disappeared from the boat during the day under unclear circumstances. The timeline and specific events aboard the Arctic Trawler leading to his disappearance are not publicly known. The Alaska State Troopers handled the official investigation and search efforts, but Mark was never located.

The remote Aleutian Islands and the Bering Sea present serious challenges for search operations, and this case remains unresolved. If anyone knew Mark, worked on the Arctic Trawler, or has information about that day, please come forward.
