William Tyrrell investigation will take MONTHS as police dig up 1km of ground in Kendall
Police have found an old hessian bag buried about one metre under the ground on the sixth day of the search for the remains of missing three-year-old William Tyrrell – as forensic scientists say ‘he’ll be in there’.
Police are focusing on three potential covert burial sites within 700m of William’s late foster grandmother’s home in Kendall, on the NSW mid north coast.
The three-year-old was last photographed on the balcony of the property in 2014.
The frayed green nylon bag was found in a deep hole police have dug at Area 1 of the Tyrrell dig and was inspected, mapped with evidence marker ‘F’ and placed into an evidence bag.
The spot where it was found is near a tree trunk which has interested specialists on site, in particular anthropologist Dr Penny McArdle.

It is the sixth piece of evidence police have found since beginning the search for the missing toddler’s body on Monday.
The find came as police have confirmed that the dig could now take months and will cover an area up to one square kilometre.
Police told Daily Mail Australia on Saturday that forensic hydrologist and layers expert Professor Jon Olley and graves specialist Dr Tony Lowe had advised excavators to scrape off dirt down to a layer 15 and 30cm below the surface.
‘He’ll be in there,’ a police spokesman said the scientists have told officers working on the scene.

The search for the remains of missing three-year-old William Tyrrell is entering its sixth day. Forensic scientists have told police ‘he’ll be in there’ as they dig up bushland near his late foster grandmother’s home
‘Between half a foot and a foot down and once they get down through the top soil into the orangey clay they know that’s well into seven years down.
‘They are scraping back seven years (of dirt).’
The major development comes after police dug up and raked through dirt and drained a shallow creek in an area of bush a kilometre from the property on Friday.
A piece of fabric was collected from the creek-bed and placed in an evidence bag.
The discovery created immediate interest, with a police officer taking a camera, evidence bag and gloves to meet forensic specialist Professor Olley.
A find two hours earlier of a fabric sample by the same pool had been immediately discounted by the professor.
But on the second occasion, he spent up to 10 minutes with the officer as she photographed it in situ, donned gloves, poured a liquid on the item and bagged it in a a brown paper evidence pack.
The latest evidence was found on the right side of a stagnant end of the creek drained last night.
The light blue-coloured piece of fabric, measuring roughly 8cm x 8cm will be taken back to the NSW Forensic Medicine headquarters in the Sydney suburb of Lidcombe.
