Michael Ray Johnson, 31, was last seen on the back deck of the tugboat Ensco Giant in Prince William Sound on August 17, 1989. He was wearing blue or black jeans, a t-shirt reported as blue, red, or white, a blue down vest, brown rubber boots and a brown engineer cap. Identified also as Mike Johnson, Michael Roy Johnson or Michael Johns, he had blond or strawberry blond hair, brown eyes, scars on his left eyebrow, forehead and nose, and a left-shoulder tattoo of a bull with the word Taurus.

A report was filed with the Alaska State Troopers the day after he disappeared. It is believed he fell overboard, but that explanation remains unconfirmed and the case is still open with the Alaska State Troopers Missing Persons Clearinghouse.

Did anyone who worked on or around the Ensco Giant in August 1989 see Michael that day or notice anything unusual on the tugboat?
