CBC said that it had been shown the results of a Thai autopsy that concluded the sisters had died after drinking a variation of the the teenage cocktail see koon loy (4x100).
See koon loy consists of four ingredients: cola, cough mixture, Kratom (a mildly narcotic leaf) and ice.
What 20-year-old Audrey Bélanger and her sister Noémi, 25, drank also had the insecticide Deet mixed into it.
CBC reported, “It is thought that an overdose of Deet was accidentally mixed into the young women’s drinks.”
The sisters were found dead in their room on June 15 and initial examination suggested poisoning of some kind. Police said there were no signs of foul play.
After the autopsy in Bangkok, the two bodies were shipped back to Canada where they are curently undergoing more scientific examinations. The results of those are not expected for “months”, CBC said.
