Ellard conviction overturned in death of Victoria teen Reena Virk

Story here. Excerpt:

"The B.C. Court of Appeal has overturned Kelly Ellard's second-degree murder conviction and ordered a fourth trial for her in the death of teenager Reena Virk, who was found beaten and drowned in a Victoria waterway in 1997.
...
[Virk] was 14 when she was swarmed and beaten under a bridge in Saanich on Vancouver Island on Nov. 14, 1997, by a group of teenagers who were mainly girls, police said. Battered and bloodied, Virk managed to get up and stagger across the bridge toward a bus stop to make her way home. But two of the original attackers dragged her back, hit her again and left her in a waterway."

Does it get any more brutal than this?
