Alaskan fishing boat massacre claimed eight lives but remains unsolved

Some 35 years have passed since a horrific massacre aboard a fishing boat in Alaska claimed the lives of eight people — but the case still remains unsolved.

The tragedy gripped the nation in September 1982 after the mystery killer boarded the vessel, called the Investor and moored in the town of Craig, and shot dead everyone on board.

Those who died were the skipper Mark Coulthurst, 28, of Blaine, Washington, Coulthurst’s pregnant wife Irene, 28, their two small children and four teenage crew.

The killer then took the fishing boat about a mile out to sea and tried to sink it, before taking a small boat back to shore. When the Investor was still afloat the next day they then returned, covered it in gasoline, and set it alight.

After putting out the flames, state troopers discovered the dead bodies on board. In 1984, suspect John Peel — who once worked for Coulthurst — was charged with the killings, but after two high-profile trials he was found not guilty.

He later won a reported $900,000 after filing a wrongful prosecution lawsuit. The case remains unsolved to this day.
