Three-year-old Cheryl Grimmer vanished from Fairy Meadow beach at Wollongong in 1970. A teenager later told police he had abducted and killed her. Decades on, he was charged with murder—but the case ended when a judge ruled that his police interview could not be used at trial. He pleaded not guilty, and no jury reached a verdict. After a tireless campaign  for justice by Cheryl's family, the NSW Director of Public Prosecutions agreed to review the court ruling but recently upheld the decision to exclude the confession of the alleged killer. It was a devastating blow but the family fights on. They are now demanding an independent review of this decision and why evidence from new witnesses has not been investigated by police. In this From the Desk, Adam Shand asks how a family finds answers when the evidence at the heart of a case cannot be heard in court.
