A Mystery in Bangkok: Six People Found Dead in Hotel Room

Six people were found dead on Tuesday under mysterious circumstances in a hotel room at a Grand Hyatt in the heart of downtown Bangkok, police officials said.

Two of the dead were Americans of Vietnamese descent and four were Vietnamese nationals, according to Prime Minister Srettha Thavisin. Police Lt. Gen. Thiti Saengsawang, the Metropolitan Police commissioner, said three of the dead were men, and three were women.

Mr. Srettha told reporters that the crime scene did not show any signs of a robbery or fight. The belongings of the six people were still intact, and none of the plates or cups in the room were broken, according to General Thiti.

Police Maj. Gen. Theeradej Thumsutheeh, chief investigator of the Metropolitan Police Bureau, said initially that the six appeared to have been poisoned. But General Thiti later walked that back, telling reporters, “We are not saying they were poisoned.”

“There was an intention to take their lives,” he said, adding that as of now, the police have concluded, “None of them harmed themselves.”

A tour guide was being questioned, according to Police General Theeradej.

Five of the bodies bore no visible injuries, according to General Thiti; the sixth had facial wounds that forensic investigators said they thought were caused by the person falling and hitting a hard surface.

It appeared that a man and a woman had tried to make it to the door of the suite but fell down before they reached it, he said.

General Thiti said officials believe that the six people, whose bodies were discovered by a hotel housekeeper, had been dead for more than 20 hours. They had ordered room service after 1 p.m. on Monday, and investigators found residue at the bottom of six cups, he said.
