The accused, Tyrelle Lee and Steven MacIsaac, were charged with second-degree murder following a fatal stabbing at a park party.
A verbal altercation escalated into a physical melee, during which the deceased was chased to a hill and stabbed once in the chest by Lee.
MacIsaac was present, armed with a knife, and assisted in preventing the deceased from escaping.
The court found that while Lee caused the unlawful death, the Crown failed to prove the requisite intent for murder beyond a reasonable doubt.
Both accused were found guilty of manslaughter, with MacIsaac convicted as a party to the offence for aiding and abetting.
