Six people, including two Americans and four Vietnamese, were found dead from cyanide poisoning in a room at the Grand Hyatt Erawan Hotel in Bangkok. The victims, aged 37 to 56, were discovered on Tuesday after failing to check out, with evidence of cyanide found in their blood, cups, and thermoses. The deaths are suspected to be linked to a business dispute over a $250,000 investment in a hospital project in Japan. Police believe that one of the victims poisoned the others, as there were no signs of forced entry or physical violence. Investigations are ongoing, and the U.S. State Department and the Vietnamese Embassy are involved. Authorities are also looking for a seventh individual connected to the group.
