Man who shot former boss at Christmas party loses bid to have sentence reduced

VANCOUVER - A Vancouver man who shot and killed his former boss at an office Christmas party a day after he was fired has lost an appeal of his prison sentence.

Eric Kirkpatrick was charged with first-degree murder but convicted of second-degree murder and handed life in prison with no chance of parole for 15 years for killing Ben Banky in 2008.

On appeal, Kirkpatrick's lawyer called for a 10-year parole eligibility, arguing that the trial judge didn't put enough weight on mitigating factors like the man's epilepsy and his psychological state at the time.

But a three-judge appeal court panel rejected the argument, ruling the sentence is fit.

Late last year, the B.C. Court of Appeal rejected Kirkpatrick's bid to have his conviction reduced from second-degree to manslaughter saying the murder was planned and deliberate.

Kirkpatrick, now 66, was arrested a couple of hours after the shooting and told police he killed his former boss because he'd ruined his life.
