Possible accident
According to the story, at some point in or around June 1947 (Gaddis and others list the approximate date as early February 1948), two American vessels navigating the Strait of Malacca, City of Baltimore and Silver Star, among others, picked up distress messages from Dutch merchant ship Ourang Medan. A radio operator aboard the troubled vessel sent the following Morse code message: "S.O.S. from Ourang Medan * * * we float. All officers including the Captain, dead in chartroom and on the bridge. Probably whole of crew dead * * *." A few confused dots and dashes later two words came through clearly. They were "I die." Then, nothing more. When Silver Star crew located and boarded the apparently undamaged Ourang Medan in a rescue attempt, the ship was found littered with corpses (including the carcass of a dog) "[s]prawled on their backs, the frozen faces upturned to the sun with mouths gaping open and eyes staring, the dead bodies resembled horrible caricatures", with no survivors and no visible signs of injuries on the dead bodies. A fire then broke out in the ship's No. 4 cargo hold, forcing the boarding parties to evacuate the Dutch freighter, thus preventing any further investigation. Soon after, Ourang Medan was observed to explode and sink.
