Initial autopsy results showed traces of cyanide in the blood of six people who were found dead in a room at a central Bangkok luxury hotel. The bodies were found Tuesday in Grand Hyatt Erawan Hotel in downtown Bangkok. They had last been seen alive Monday afternoon when food was delivered to the room. Police said cyanide was found in drinking containers. On Wednesday, medical officials said cyanide was likely the cause of death. The dead were two Vietnamese Americans and four Vietnamese nationals — three men and three women. Officials say a husband and wife among the dead had invested about $278,000 with two of the others, suggesting money was a motive.
