A Muskoday First Nation woman has been found guilty of second-degree murder in the death of her fiancé.

A jury at a Prince Albert, Sask., court found Robyn Laura Ermine guilty in the February 2015 fatal stabbing of Evan Tyler Bear after eight hours of deliberation Wednesday night.

Bear died from blood loss after one of the stab wounds, suffered during a fight between the two, cut an artery.

Ermine’s defence lawyer argued the killing was an act of self-defence. He said Bear, who had 100 pounds and six inches over Ermine, was choking her and that Ermine reached for what she thought was a knife sharpener to hit him.

The jury didn’t buy the narrative.

The Crown’s story stated Ermine wanted to win the fight, arguing her stabbing motions showed she knew she had a knife in her hand.

A recording of the 911 call made the night of the stabbing and video of the crime scene were shown during the week-and-a-half trial. Eyewitnesses included Ermine and her stepsister.

Second-degree murder carries a mandatory punishment of life in prison with no chance of parole for at least 10 years.

Bear’s family erupted in tears when the verdict was read.

The judge will determine Ermine’s parole eligibility at a later date.
