Six individuals, including four Vietnamese nationals and two Vietnamese Americans, were found dead in a locked room at Bangkok's Grand Hyatt Erawan hotel, with traces of cyanide in their bodies suggesting potential foul play.

Authorities are investigating a suspected cyanide poisoning at a luxury Bangkok hotel where six people were found dead, raising questions about a possible murder linked to disputes over multi-million Baht investments. Evidence points to one of the victims potentially poisoning the others, with untouched food and consumed drinks found in the room. The high-profile case, which involves cooperation from the FBI and both Vietnamese and U.S. embassies, has been declared non-terroristic by the Thai Prime Minister and is not expected to impact local tourism or a scheduled conference.

The tragic discovery was made by a hotel staff member who noticed that the room had not been accessed for some time. The room was locked from the inside, and the staff member had to use a master key to enter. Upon entering, the staff found the bodies of four Vietnamese nationals and two Vietnamese Americans. The room was part of the Grand Hyatt Erawan, a luxury hotel situated in Bangkok, Thailand.

The deceased were identified as Nguyen Thi Phuong Lan, Sherine Chong, Nguyen Thi Phuong, Tran Dinh Phu, Dang Hung Van, and Hong Thanh Pham. Initial autopsy reports confirmed the presence of cyanide in their bodies, pointing to poisoning as the cause of death. Further, traces of cyanide were also identified on cups, teapots, and thermoses within the room, reinforcing this suspicion.

Investigations suggest that one individual among the six might have poisoned the others. Forensic evidence indicates that this theory could be plausible, but the definitive identity of the perpetrator remains uncertain. The police found that drinks had been consumed, but food ordered via room service was left untouched inside the room. It was last recorded that the six individuals were alive on Monday afternoon when the meal was delivered.

Two of the victims appeared to have attempted to reach the door before collapsing and succumbing to the effects of the poison. These details dismiss the possibility of a mass suicide event as some of the victims had future travel plans, a fact noted by the investigators.

Relatives of the victims unveiled that there had been a financial dispute among the group. The dispute was said to involve debts pertaining to multi-million Baht investments, or possibly a bad investment. This financial angle forms a significant part of the investigation as it might shed light on the motive behind the tragic deaths.

The bodies were found spread across different parts of the hotel room. Four of the victims were found in the living room while two were discovered in the bedroom.

The high-profile nature of the case has led to an international collaborative investigation effort. The FBI is assisting local law enforcement, while diplomatic representatives from both the Vietnamese and U.S. embassies are actively involved to ensure thorough uncovering of the facts. This level of cooperation is aimed at securing justice and providing answers to the families of the deceased.

Prime Minister Srettha Thavisin has publicly stated that this incident is not connected to terrorism and should not deter tourists or impact a significant conference scheduled at the hotel. Thai authorities are focused on ensuring public safety and maintaining confidence in the tourism sector, which is a critical industry for the nation's economy.

Preliminary analysis and ongoing investigations will continue as law enforcement agencies work meticulously to compile a complete picture of the circumstances surrounding these deaths. Meanwhile, the hotel management has expressed condolences and is fully cooperating with the authorities. The Grand Hyatt Erawan is currently assessing additional security measures to reassure guests and prevent future incidents.
