Six dead in cyanide poisoning at luxury Bangkok hotel, including US citizens
Local police suspect that the killer was among those who died, all of whom were Vietnamese.
Authorities in Thailand are investigating the deaths of six Vietnamese, two of whom have U.S. citizenship, at a luxury hotel in Bangkok, with cyanide poisoning as a likely cause.
The six—three women and three men—were found dead in a room at the Grand Hyatt Erawan hotel by a staff member on July 16. Local police said there were no signs of physical violence on the bodies.
Bangkok police chief Lt. Gen. Thiti Sangsawang said the victims checked into separate rooms upon their arrival over the weekend. He noted that police were still searching for a seventh person connected to the victims.
“The property as far as we can see has not been ransacked,” Gen. Sangsawang told reporters, suggesting that the deaths may not have been caused by an outsider.
He said that police believe the victims did not harm themselves and suspect that the killer was among the dead.
Local officials said that traces of cyanide were detected on drinking glasses and a teapot in the room where the bodies were located.
The bodies were sent to Chulalongkorn Hospital for autopsy and traces of cyanide have been detected.
“We can assume that the six died from cyanide,” Chulalongkorn Hospital’s official Kornkiat Vongpaisarnsin told reporters. Authorities were still investigating how the cyanide was obtained.
“We offer our sincere condolences to the families on their loss,” he said.
Mr. Miller said that local authorities were responsible for the investigation.
“We do reach out to local authorities often to communicate with them when it involves the death of a U.S. citizen, and we will certainly be doing so here,” he said.
Vietnamese Foreign Ministry spokesperson Pham Thu Hang confirmed that four of the victims were Vietnamese citizens and that Vietnamese authorities are in the process of verifying their identities.
The spokesperson said the Vietnamese Embassy in Thailand will closely coordinate with local authorities to determine the cause of the deaths.
