 We're learning more about the apparent cyanide poisoning deaths of six people, including two Americans at a hotel in Bangkok. Here's ABC's James Longman. Police say a waiter was the last to see one of the Americans alive. He delivered food and tea to the room. Surveillance video shows the others enter one by one. Authorities believe that one among them must have administered the poison to the drinks. Police think money may have been the issue. The six victims invested together. Two of them owed hundreds of thousands of dollars.
