A jury has been unable to reach a unanimous verdict in the trial of a man accused of murder after a young woman was fatally stabbed on an isolated beach. Toyah Cordingley, a 24-year-old organic food store worker, was found buried in sand at a beach outside Cairns in far north Queensland on 22 October 2018. Former hospital nurse Rajwinder Singh, 40, from nearby Innisfail had pleaded not guilty to murder. The jury had begun deliberating on Friday after being shown graphic autopsy photos during a 13-day trial in the supreme court in Cairns and hearing from hundreds of witnesses.
