Two Canadian sisters found dead in a hotel room in Thailand may have died from food poisoning caused by blowfish or poisonous mushrooms.
Audrey and Noemi Belanger, aged 20 or 26, were found by a maid on Friday after staff at the Phi Phi hotel noticed they had not been seen for three days.
Officials who examined the bodies said the pair were covered in vomit, had skin lesions and had been bleeding from the gums. Both sisters had blue fingernails and toenails.
A Thai doctor who has conducted a preliminary investigation believes the women were victims of severe food poisoning.
"The source could have been a meal which included blowfish or poisonous mushrooms," Krabi hospital director Dr Komkrit Phukrityakame told The Phuket News.
Local police are remaining tight-lipped on the matter, saying it is too early to determine the cause of the deaths.
"We will send all evidence to Bangkok's forensic department this afternoon and ask them to process it quickly to establish what killed them," Krabi province police chief Jamroon Reunrom said.
"I prefer to wait for formal results from the police forensic team in Bangkok."
