Defence continued to put forward a theory Monday that Daleen Bosse may have been killed by high levels of alcohol consumption combined with prescription drugs the night she died on May 18, 2004.
Douglas Hales is on trial for first-degree murder in the death of the 25-year-old Onion Lake Cree Nation woman.
Toxicologist Wayne Jeffery told court that Bosse’s medical records show no indication she was more than a social drinker and that she was on the anti-depressant paxil at the time of her death.
He said based on defence estimates of the amount of alcohol Bosse allegedly consumed on the night in question, lethal poisoning could have been possible.
Jeffery also said the mixture of anti-depressants and alcohol can increase impairment but to make it a life-threatening situation a person would be virtually comatose – unable to walk or talk.
It is impossible to make an exact determination of Bosse’s blood alcohol level as her remains were burned and investigators were unable to perform an autopsy.
The Saskatoon trial continues on Tuesday.
