PHUKET, Thailand - Police in Thailand are investigating the cause of death of two Canadian sisters found dead in their hotel room.
The Phuket Gazette quotes a spokesman with the Phi Phi Island police saying they received a report Friday night about two tourists' bodies being found in a room.
The Gazette says the sisters, one aged 20 and the other aged 26, checked in to the Phi Phi Palms hotel Tuesday.
It says the two went out that night but stayed in their room all day Wednesday and by Friday, hotel staff had become concerned and went into their room to check.
Police say officers at the scene believe the women had died about 12 hours before their bodies were found.
Poisoning is suspected in the deaths but tests are being done to try to determine the cause of death.
