Three crewmembers found dead on a South Korean freighter that
washed ashore in Shimane Prefecture on Sunday may have died after
inhaling toxic gas generated from rotten squid organs, local Japan
Coast Guard (JCG) officials said.  Three crewmembers were
found dead in two storage rooms of the freighter and its skipper
was unconscious in one of the rooms.  JCG officers found
rotten internal squid organs in storage rooms where the three men
were found dead.  Investigators suspect that the three
crewmembers died from either an oxygen shortage or inhalation of
carbon monoxide that had been generated from the rotten squid
organs. The coast guard office said carbon monoxide and hydrogen
sulphide were detected in the cabin.
