The accused pleaded guilty to manslaughter after striking the victim once on the neck, causing a fatal brain hemorrhage.
A Gardiner hearing was held to determine disputed facts for sentencing.
The court found that the accused meant to cause serious bodily harm but did not have the requisite intent for murder.
The court rejected claims of provocation and found insufficient evidence that intoxication played a mitigating role, concluding the unprovoked attack occurred in very aggravating circumstances.
