White/Caucasian male, age 19, Dean Moon was a teenage deckhand aboard the 58-foot salmon seiner Investor, which tied up in the small port of Craig, Alaska, over Labor Day weekend in 1982. The boat's owner-skipper, Mark Coulthurst, had brought his family and four young crewmen—including Dean Moon, 19—to town to offload fish and celebrate the end of the season. In the early hours that followed, everyone aboard was shot and the killer tried to erase the crime by setting the vessel ablaze. On September 7, 1982, townspeople spotted the Investor anchored off Fish Egg Island and then burning; when the flames were finally beaten back, the remains of eight people—including Dean Moon, 19—were found, marking Alaska's worst unsolved mass homicide.
Witness accounts would give investigators their earliest clues. In the hours before the fire, a lone young man was seen piloting the Investor's skiff back toward Craig and later returning to shore in a seemingly calm, deliberate manner. That same morning, townspeople recalled a man—slight build, baseball cap, pockmarked complexion—buying gasoline, the very fuel believed to have been used to torch the boat. These fragments of memory, gathered from fishermen and locals who crossed paths with the skiff and its driver, formed the backbone of a case otherwise gutted by fire and tide.
Two years later, Alaska State Troopers arrested a former crewman with ties to the Coulthurst operation: John Kenneth Peel. He was charged in 1984 with eight counts of first-degree murder and arson, a sweeping case built largely on circumstantial evidence and the witness sightings from the harbor and docks. Peel's first trial, a marathon proceeding in 1986, ended with a deadlocked jury after months of testimony and six days of deliberation; the judge declared a mistrial.
Prosecutors tried again. In 1988, at the end of a second trial, a jury acquitted Peel on all counts. With that verdict, the only person ever arrested in connection with the killings of the Coulthurst family and their young crew—including Dean Moon, 19—walked free, and the case drifted back into the cold, its core facts preserved mostly in the recollections of a fog-bound town and a burned vessel at anchor. Decades on, authorities and families still regard the murders as officially unsolved, the specter of the skiff and its driver lingering over the water where the Investor burned on September 7, 1982.
