Detectives also searched a second-storey balcony following a theory the boy may have fallen to his death. Forensics specialists in Kendall, New South Wales, also searched for human remains in the garden of William’s foster grandparents. Photos released showed officers using giant sieves to filter through soil, which a forensic expert said was typical when looking for human remains.
