The mother of murdered Victoria teenager Reena Virk says she cannot understand why the B.C. Appeal Court has overturned the conviction of Kelly Ellard in connection with Virk's death in November of 1997.

Suman Virk says the family is stunned by the ruling that orders a fourth trial for Ellard.

Six other teenage girls were convicted of assault in 1998 for the swarming-style beating Reena received before being attacked and drowned in a Victoria-area inlet minutes later.

Warren Glowatski was convicted of second degree murder for his role in the drowning and is already on parole but Ellard has always insisted she is innocent

Ellard has been tried three times, resulting in one hung jury and two convictions that have both been successfully appealed.
