A Saskatchewan woman who fell asleep at the wheel, causing a fatal rollover crash has been found not guilty of dangerous driving causing death.

Marilyn Hunter was charged in April 2012 after the vehicle she was driving veered into a ditch and rolled over, killing 22-year-old Ryan Dubois.

Hunter, 34, admitted to falling asleep at the wheel on her way home from Regina, after she had stayed up all night and consumed a few drinks.

On Thursday, Queen’s Bench Justice Catherine Dawson said she wasn’t satisfied beyond a reasonable doubt that Hunter knew or ought to have known her fatigue posed a danger.

Hunter, 34, was originally also charged with impaired driving causing death and exceeding .08 causing death after the crash, which occurred on Highway 15 about three kilometres east of Punnichy.

Dawson found there wasn’t enough evidence to convict Hunter of exceeding .08 causing death. The Crown previously stayed the charge of impaired driving causing death.

A trial heard in February that Hunter was driving below the speed limit at the time of the crash, and that her blood-alcohol level was measured at .097.

The court heard weather and road conditions were good at the time, and that RCMP ruled human error caused the fatal crash.

Dawson later ruled the blood-alcohol evidence inadmissible after she found that police didn’t have reasonable grounds to request a test.
