More than 15,000 pieces of information and lines of inquiry over the last three and a half years brought the police contingent back to the location on June 13, led by Detective Chief Inspector Gary Jubelin where the three-and-a-half year old disappeared without a trace on September 12, 2014.

The new search is in its second week and has a forensic focus, over an area of three square kilometres. The investigation is expected to take about three to four weeks. 

The Strike Force want absolute certainty they have the investigation covered should it result in an arrest or go to an inquest.

Det Ch Insp Jubelin said the  purpose of the evidence, ‘whether it’s presented to a court – coroner or criminal – is to prove that beyond reasonable doubt, William’s disappearance was the result of human intervention and not misadventure’.

Benaroon Drive resident Cheranne Garcia said she wants to put a stop to negative messages about their community published by various media outlets since the investigation started. 

“Our kids aren’t living in constant fear,” she said. 

Cheranne has three children and said they have had a normal life and were allowed the same freedoms as any others their age. 

She said her children grew up playing in the bush, making makeshift camps in their backyard and playing near the dam. 

“They have never had any reason to be worried or concerned,” she said. 

“My youngest still rides his bike into town.” 

Cheranne said in the first year of William’s disappearance, there was a lot of interest in the street and the family was wary of strangers who visited the quiet residential location. 

“However I’ve never had a reason to feel uncomfortable,” she said. 

The disappearance of William is still something which Cheranne finds hard to believe. 

“It’s such a lovely community and the people I know could never have done such an evil act,” she said. 

Fifty officers from the Public Order and Riot Squad are involved in the bushland search surrounding the property from where William vanished. The property at the time was owned by his grandmother and he was visiting with his foster family on the day of his suspected abduction.

Owner of Miss Nellie’s Cafe in Kendall Jenelle Nosworthy said she hopes the investigation can provide closure for not only the family of William, but also the community of Kendall. 

Jenelle said the investigation had ‘put Kendall on the map for all the wrong reasons’. 

“It’s unfair that it’s put the spotlight on what is such a peaceful town and it’s a shame that it’s known because of it,” she said. 

Jenelle said, despite what has been reported in the media that Kendall has suffered because of the incident, it’s just not true. 

“Business here is doing really well, the Kendall Tennis Club has grown exponentially in young members, the skate park is always busy and kids still catch the bus to school everyday,” she said. 

Det Insp Jubelin said time will be no barrier to finding evidence, he said, despite the fact the region has experienced the extremes of weather conditions over the last three years.

He refused to conclude the search for William had exhausted all possibility of an outcome.

"We have not given up on this investigation. We are committed to finding out what happened to William. We are mindful it has been three and half years since William disappeared and we still have not solved this matter,” he said.

The Tyrrell case will go to an inquest if it can’t be solved from a criminal perspective. But Det Insp Jubelin said there are still strong lines of inquiry and people of interest that have the focus of the Strike Force.

He said among those many lines of inquiry were early allegations of an active paedophile ring operating out of the mid north coast.

“Until this matter is solved we will keep all lines of inquiry open. We need conclusive evidence before I can say one thing or another. That line of inquiry was a legitimate line of inquiry that we’ve explored and that didn’t provide any information that led to the charging of any person or the recovery of William.

“What we have done is build up a database of evidence that we readily refer to. The search we are doing and the defined areas we are looking at is for a reason.

“Everything we do is planned. There is strategy behind every time we talk to the media and every inquiry we do. It's not done in an ad hoc fashion.

“We've got a deliberate plan and it was coordinated at this time because it suited the investigation.”

William was taken into foster care at 11 months old.

Police have previously ruled out his foster and biological families as having played a role in his disappearance.

A $1 million reward, unique in that it’s offered for the recovery of William and not the conviction of a person, still stands. 

“We strongly believe there are people out there who have information on this and I make a point to those people – if you do have information concerning what happened to William you are at risk of committing a criminal offence by concealing an offence if you do not come forward,” Det Insp Jubelin said.

“I suggest you come to us before we come to you.”

Strike Force Rosann continues to brief the family on the investigation and the latest leads and thanked the Kendall community for its ongoing support.
