Where did the crew and the Briggs family go missing on the Mary Celeste?

On December 4, 1872, the Mary Celeste was discovered by the crew of the Brig Dei Gratia , some 600 miles west of Portugal. The ship was sailing without captain, crew, or captain's family. The last entry in the ship's log was dated November 24, 1872 locating the ship about six miles off Saint Mary's Island in the Azores. The only lifeboat on the Mary Celeste, a yawl located above the main hatch, was missing. The peak halyard, used to hoist the main sail, had disappeared. A rope, perhaps the peak halyard, was found tied to the ship very strongly and the other end, very frayed, was trailing in the water behind the ship. No one knows what happened to the people aboard the Mary Celeste as their remains were never recovered nor did they ever turn up alive. Whatever occurred is still the largest nautical mystery in the history of sea travel.
