The forensic team said the autopsy included collecting photographic evidence and samples, including blood, urine, and more. The team found no signs of trauma or anything unusual. All six bodies showed signs of hypoxia.
They took blood for cyanide screening in the laboratory and the initial results were that all six cases tested positive for cyanide.
A representative of Chulalongkorn Hospital said more tests were being conducted. According to Reuters, Thai authorities on July 17 also said that the six victims died from cyanide poisoning.
Mr. Trirong Phiwpan, head of the Thai police evidence department, said that after the staff brought cups of tea, two hot water bottles, milk and tea pots..., one of the six victims added cyanide.
Traces of the fast-acting deadly chemical were found during an autopsy on a drinking glass and teapot in a room at the Grand Hyatt Erawan hotel, according to police and the hospital.
Police interviewed relatives of the three women and three men killed and said the group had a dispute over a debt related to an investment and were investigating how the cyanide was hidden.
