A team of up to a dozen officers spent much of Thursday searching an area of vegetation less than one kilometre from his foster grandmother's Kendall property, on the NSW Mid North Coast, where he was last seen alive seven years ago.
Much of NSW is expecting rain over the next seven days but the search is expected to continue unless the rain is torrential. The material was compared to a Spider-Man suit - he was last dressed in before he was reported missing - and put into evidence bags for forensic investigation. Ground penetrating technology was used to scan below a roughly two square metre cement slab that was poured after William disappeared in 2014. Picture: NCA NewsWire / Peter Lorimer
Earlier this week police officers dug up a section of dirt and garden underneath the balcony of the Benaroon Drive house.
