On Wednesday, Thai police said they had found traces of cyanide in glasses and cups near the six victims found dead the day before in a luxury hotel in Bangkok and are considering debt as a motive for the alleged crime.
At a news conference, police forensic division chief Trairong Piwpan said all the victims, four Vietnamese and two Vietnamese-Americans, were suspected of having died from poisoning, although this will be confirmed by autopsy results on Thursday.
After interviewing several people who were close to the victims, officers suspect that one of the deceased poisoned the others with cyanide and then committed suicide with the poison.
On Tuesday afternoon, the management of the Grand Hyatt Erawan hotel, located in a central tourist district of the capital, notified the police of the discovery of the bodies of three men and three women, apparently poisoned.
