Randolph Berle Johanson, 45, was last seen in late winter 1982 when he left Shelter Island Marina in Richmond on February 28. He was piloting his 26-foot salvage tug while towing Laurence Peterson’s 43-foot wooden halibut boat; both men and both vessels never reached their destination of Lund. Peterson’s girlfriend reported them missing on March 3, 1982, and an official search found no sign of either man or either boat.

Johanson is described as about 5 feet 10 inches and 170 pounds, brown hair, blue eyes, a gap between his front teeth and a one-inch scar on his left breast. He reportedly used numerous aliases, including Michael Schwabe, Glen Stewart and Frank Cameron as well as variations of his own name, a fact that has fed speculation that he might have chosen to disappear. No concrete evidence has ever emerged to show either man started new lives, and no wreckage from either vessel has been found.

What details about their plans, contacts or recent movements might still help explain what happened to Johanson and Peterson?
