The Bloody Mystery of the John Dwight

On April 6, 1923, dense fog blanketed Vineyard Sound off the coast of Martha's Vineyard. Amid the eerie silence, the steam trawler John Dwight was found sinking, heavy with a cargo of illegal Canadian ale. What should have been a routine Coast Guard response to a vessel in distress quickly spiraled into one of the most gruesome and baffling maritime murders of the 20th century.

The early 1920s were the golden age of rum-running, thanks to the U.S. Prohibition laws. Smugglers routinely ferried liquor from Canada to the northeastern coast, and the waters near Martha's Vineyard were a known hotspot for these clandestine voyages.

The John Dwight, a 107-ft steam trawler, was one such vessel. Loaded with Frontenac ale and whiskey, it was headed for a secret drop-off. But instead of completing its run, it met a violent end.

When fishermen and Coast Guard boats reached the scene, they were met with horror. The John Dwight was already half-submerged. Seven bodies were recovered floating in lifejackets, with clear signs of violence: blunt-force trauma, slashed faces, and even mutilated fingers and burned-out eyes to prevent identification.

An eighth body was later found in a lifeboat, bringing the total known dead to eight.

Investigators quickly realized the John Dwight had been scuttled intentionally. The seacocks had been opened to flood the ship, and up to $100,000 in cash was believed to have been onboard, never recovered.

Witnesses reported seeing a small lifeboat with three men rowing toward Naushon Island—possibly the vessel's captains or the masterminds of the slaughter. These men were never found.

The prevailing theory? A heist by insiders, eliminating the crew to cover their tracks and vanish with the money.

To this day, the John Dwight lies beneath Vineyard Sound in 85 to 100 feet of water, largely intact. It remains a favorite site for divers and maritime historians. Though the Coast Guard dropped charges to destroy remaining alcohol barrels, the mystery was never solved.

Locals whisper of rum rivalries and ghost ships. Others believe it was revenge for past crimes. But no one was ever charged, and no official suspects were named.
