A 32-year old Nunavut woman who pleaded guilty to murdering her partner was back in court Tuesday for sentencing arguments.

Joyce Kringuk of Repulse Bay pleaded guilty to second-degree murder in the death of Joani Kringayark. That crime carries a mandatory sentence of life in prison, but the court decides how long she'll have to wait before she can apply for parole.

On Monday, the court heard how Kringuk shot Kringayark at close range in front of their two children. During the sentencing hearing Tuesday, her lawyer, Peter Harte, described the evening as a perfect storm, fuelled by alcohol and ready access to a loaded firearm.

He also told the court of her troubled past that includes diagnoses of bipolar disorder and depression, at least five rapes, binge drinking starting at age eight, and gas sniffing serious enough to have caused brain damage.

There were tears in the court room as the Crown read two victim impact statements. Kringuk also sobbed as she stood to apologize to Kringayark's family.

Crown and defense lawyers agreed that 10 years before eligibility for parole is fitting. Even if she gets parole, her laywer said it's virtually certain she will never return to Repulse Bay.

Justice Robert Kilpatrick said he would deliver a written decision in a matter of weeks.
