MONTREAL - The father of the two Quebec sisters found dead in a Thai resort last June told QMI Agency their autopsies revealed they had ingested insecticide.
Carl Belanger said the autopsies conducted by Thai medical authorities revealed that significant amounts of DEET were found in the bodies of Audrey, 20, and Noemi, 25.
DEET is a commonly used insect repellant.
Resort staff on the Thai resort island of Phi Phi, in southern Thailand, found the sisters dead in a hotel room in June.
Thai authorities reportedly said there were no signs of violence in the room but there was vomit on the floor and other signs the women were poisoned.
The Phuket Wan Tourism News reported Friday a local police officer said "insecticide has been found in their bodies" following autopsies, which were conducted in Thailand.
However, the news organization reported police had no further details on the women's deaths and that it could take up to three months - "if ever" - before official results are released.
The women's remains were transported to Canada where an autopsy was conducted by the Quebec coroner's office.
Genevieve Guilbault, spokeswoman for the Quebec coroner's office, said she could neither confirm nor deny that DEET was found inside the woman's bodies.
"The investigation is not completed," she said. Guilbault said the coroner should be able to publicize his findings in the "next few weeks or months."
The Phuket Wan news also suggested in the article published Friday that DEET could have been poured into the women's drinks. The news website said the Thai resort island has a notorious reputation for hard partying.
The news website said tourists often drink "buckets," which are concoctions of alcohol and many other substances.
Belanger told QMI Agency he doesn't believe his daughters knowingly drank a noxious substance.
"They had to have drank (DEET) without knowing," he said in an interview on Friday. "To drink that much (DEET) ... these girls weren't suicidal. Maybe the country has something to hide, maybe the hotel or the bar has something to hide, and we need answers."
Belanger said he believes the women were killed by exposure to an insecticide vapour used to kill bed bugs.
He also told QMI Agency in June that he deplored the way Thai authorities handled the case. He called Thai police work "corrupt" and "rotten."
Belanger said the investigation took too long and there was little communication between Thai authorities and the family.
"(Thai) authorities said they found their bodies 12 hours after they died," Belanger said. "But according to our calculations, it was 48 hours."
The Belanger family also told QMI Agency that Quebec coroner Renee Roussel told them the women's bodies were kept for five days in Thailand under conditions that were "not respectable."
The family was not able to identify the women's bodies because they were told the sight of the corpses would be too shocking, Carl said.
Audrey and Noemi were university students from the small town of Pohenegamook, about 200 km north of Quebec City.
