Inside the Tragic Incident at the Grand Hyatt Erawan


There was little to indicate what had happened on the fifth floor of the Grand Hyatt Erawan in Bangkok until police officers opened the door. No one was heard to scream or had rung for help. No one had even made it to the door. Even inside, there were no signs of struggle the untouched late lunch still laid out neatly on the table for the occupants to enjoy.

 

From outside of Room 502, the only clue to the horror inside the locked room was the fact that the group was late checking out of the hotel. And yet, inside were six bodies, alongside teacups laced with cyanide.

 

It didn't take officers long to determine that the occupants of the room had drunk the poisoned tea or to identify the apparent victims. However, days after police revealed the grim discovery, significant questions remain, why them, and who did it?

 

Four of the victims are Vietnamese nationals, Thi Nguyen Phuong, 46; her husband Hong Pham Thanh, 49; Thi Nguyen Phuong Lan, 47; and Dinh Tran Phu, 37. The other two are American citizens of Vietnamese origin, Sherine Chong, 56, and Dang Hung Van, 55.

 

According to investigators, Chong had borrowed 10 million baht ($280,000; £215,000) from Hong Pham Thanh and Thi Nguyen Phuong to invest in a hospital building project in Japan. The couple, who owned a construction business, had apparently tried in vain to get their money back. The matter was due to go to court in Japan in a matter of weeks.

 

On the surface, this meeting appeared to be an attempt to discuss the issue before the court case. Thi Nguyen Phuong Lan was there because Chong, who U.S. media reported lived in Oakland, California, had asked her to act as her intermediary with the couple regarding the investment.

 

But how were the other two linked to the case?

 

Dinh Tran Phu, a successful makeup artist whose clientele included movie stars, singers, and beauty queens in Vietnam, was at the gathering working for Chong. His father emphasized that he had traveled to Thailand with his regular clients, not with strangers. A close friend mentioned that he knew both Thi Nguyen Phuong and Thi Nguyen Phuong Lan, having introduced them to treatments at a friend's spa in Da Nang, where he lived.

 

Dang Hung Van's participation in the hotel suite meeting was not immediately clear. Police said there was a seventh name in the hotel reservation, the sister of one of the six victims. That person returned to Vietnam from Thailand last week, and police said she was not involved in the incident.

 

What Happened in Their Hotel Suite?

 

The group checked into the hotel separately over the weekend and were assigned five rooms four on the seventh floor and one on the fifth. Chong checked into Room 502 on Sunday. The five others visited her in her suite that day but returned to their respective rooms for the night.

 

Before noon on Monday, Dang Hung Van ordered six cups of tea while Dinh Tran Phu, the makeup artist, ordered fried rice from their respective rooms. They asked for it to be delivered to Room 502 at 14:00 local time. A few minutes before 14:00, Chong started receiving the food orders at Room 502. She was alone in the suite at that time.

 

Police said she refused the waiter's offer to brew tea for her party. The waiter noted that she "spoke very little and was visibly under stress." The rest of the group started arriving soon after, with the couple lugging a suitcase. At 14:17, all six could be seen by the door before it was shut. From then on, there was no sign of movement from inside.

 

They had been scheduled to check out on Monday but failed to do so. Police entered the room at 16:30 on Tuesday and found the six dead on the floor. The initial investigation found that two appeared to have tried to get to the suite's door but failed to reach it in time. All the bodies bore signs of cyanide poisoning, which can, in certain doses, kill within minutes. Their lips and nails had turned dark purple, indicating a lack of oxygen, while their internal organs turned "blood red," another sign of cyanide poisoning.

 

Investigators say there is "no other cause" that would explain their deaths "except for cyanide." Further tests are being carried out to determine the "intensity" of the deadly chemical and to rule out any other toxins. Cyanide starves the body's cells of oxygen, which can induce heart attacks. Early symptoms include dizziness, shortness of breath, and vomiting. Its use in Thailand is heavily regulated, and those found to have unauthorized access face up to two years in jail.

 

Who Poisoned Them?

 

Police suspect that one of the dead was behind the poisoning and was driven by crushing debt, but they have not specified who. According to Vietnamese outlet VN Express, investigators said Chong had been sued by all the other five over their failed investments. The meeting in Bangkok was called to negotiate a settlement, but the attempt failed.

 

Police have sought a statement from the group's tour guide in Bangkok, 35 year old Phan Ngoc Vu. The guide reportedly said that before she died, Thi Nguyen Phuong Lan, the mediator, had asked someone to buy traditional medicine containing snake blood for her joint pains.

 

Then there are the two metal beverage containers that did not belong to the hotel, found by police in the suite. The containers were placed beside the cyanide laced teacups, near the dining table. What is certain is that officials want the matter resolved quickly.

 

Vietnamese Prime Minister Pham Minh Chinh has directed officials in Hanoi to coordinate closely with their Thai counterparts on the investigation. For Thai authorities, it couldn't have come at a worse time. Thailand had just expanded visa free entry to 93 countries to revive its tourism industry, a key economic pillar that has yet to fully recover from the pandemic. Barely a year before, a 14 year old boy shot dead two people at a luxury shopping mall in Bangkok.

 

Prime Minister Srettha Thavisin was with police on the scene at the Grand Hyatt on Tuesday night. He said there was no danger to public safety and that it was a private matter. For the families left behind, the shock is palpable.

 

The mother of the makeup artist was so distraught that she hung up after a brief conversation. She thought her son was just on a routine work trip. His father, Tran Dinh Dung, said in a separate interview that he did not notice anything strange with his son the last time he saw him.
