The bodies of a Thai-Indian couple have been sent to Police General Hospital for a thorough autopsy after they were drowned in a resort pool on Koh Tao on Friday.
Koh Tao police chief Pol Col Kriangkrai Kraikaew said on Sunday the body of Rakeshwar Sachathamakul, 59, and his wife Anshoo, 55, had been transported to the hospital in Bangkok to determine the cause of the deaths and the result is expected in two weeks.
Although an early examination found no signs of foul play, police on the island and investigators sent by the Crime Suppression Division (CSD) are collecting evidence from security television cameras installed along their travel route from the pier to the hotel.
Closed-circuit cameras at the Jamahkiri Resort & Spa on Friday, where they stayed, were not functioning at the time.
The pair and their son Ratish Sachathamakul, 34, arrived on Koh Tao from Chumphon on Friday for a vacation.
Mr Ratish alerted police after he found his parents lying in the water after they checked in and the couple went swimming in the pool, Pol Col Kriangkrai said on Saturday.
Investigators were told that Rakeshwar had some underlying health conditions, including diabetes, hypertension and obstructive sleep apnea, he said.
The Koh Tao police chief gave more details on Sunday, saying a hotel staff member found Rakeshwar lying near the pool ladder, while his wife was found in an area where the water was one metre deep. No hotel staff were in the area when the incident took place, he added.
“We are looking into all aspects to find the conclusive reasons for their deaths,” he said.
Pol Col Weeracharn Khunchaikaew of the CSD said all witnesses would be interrogated in the investigation, although family members had expressed no suspicions about the deaths.
Rakeshwar was the co-owner and CEO of the Novotel Phuket Kamala Beach hotel in Phuket and the owner of the Bangkapi Mansion apartments on Sukhumvit Soi 12 in Bangkok.
He was the managing director of Wireform A.N. (Thailand) Co, a manufacturer of precision springs and plastic parts for the automotive and other industries, with plants in Rayong and Prachin Buri.
