William Tyrrell: More items unearthed in William Tyrrell bush dig

Police are finding more and more foreign items buried in the bush near Kendall, which they suspect could be William Tyrrell’s final resting place.

A massive pit of buried rubbish and debris has become the focus of the expert grave diggers and senior police searching for William Tyrrell.

Dozens of officers from Strikeforce Rosann spent Monday clearing bush and literally combing through the dirt on a roadside outside Kendall in the renewed search for the missing toddler.

They were effectively just scratching the surface down to the sedimentary layer of 2014 - the year William vanished from his foster grandmother’s home less than a kilometre away.

A piece of tattered fabric or cord was pulled from the bush and bundled into evidence at about lunch time on Monday.

Detectives are working on the theory the little boy was dumped in the bush, rather than buried, but it’s not yet known why they narrowed their search to one patch of bushland among so many others.

But the officers searching the bush were sent home after 3pm leaving just the experts and a handful of senior police who used an excavator to dig a pit about 10 metres away.

The excavator had been taking off just centimetres of dirt with each scoop throughout the morning so officers could sift through every bucket load - then it picked up the pace.

By late afternoon the excavator was pulling out massive piles of dirt but also what appeared to be household debris; bottles, broken machinery and pieces of rusted metal.

By the time the dig was called off the pit was almost a metre and a half deep and two metres wide.

The search effort had been hampered by constant and heavy rain throughout Monday.

CADAVER DOG CALLED IN

Police with chainsaws and a cadaver dog have begun rapidly advancing into a new section of bushland after finding a new potential clue in the search for missing toddler William Tyrrell.

Police are literally combing through tonnes of soil in muddy bushland south of the NSW town of Kendall determined to miss nothing that could solve the seven year mystery.

Sustained rain has slowed the operation but on Monday the bush gave up what appeared to be reddy-brown string or cord.

A yellow exhibit marker was put down to mark the spot the cord was found as police carried the foreign item to a forensics van parked nearby.

An hour later the officers scraping through the dirt downed their tools and marched further into the dense bush clearing out debris for what will become the next part of the dig.

A cadaver dog named Wag and his handler Senior Constable Chris Hill followed the officers searching for any sign of a body in the disturbed scrub.

But Wag did not appear to indicate anything and was taken away.

An excavator has also been deployed to dig a large hole in a yard near to the bushland.

Police are sifting through each scoop of dirt brought to the surface as archaeological experts watch on.
