In June last year, Mark and Julie Wallace were forced to face every parent’s worst fear when their 21-year-old daughter Sara Zelenak went missing after a terror attack in London. For three days, their desperate calls and messages to the young nanny went unanswered as they found themselves caught up in the world of international terrorism, dealing with Scotland Yard, phoning hospitals and navigating the news media from their Redland Bay home. They were en route to London when they received the news that Sarah had died. A year after their daughter’s death, Sara’s parents are making sense of the senseless act of terror by focussing on building a fitting legacy to Sara. They’re working towards building "Sarz Sanctuary", a healing retreat to help others facing unimaginable grief and trauma.
