William Tyrrell dig unearths item compared to spiderman suit, but ruled out of investigation

Ground penetrating radar technology is being used in the search for missing boy William Tyrrell.

For a brief moment today, Strike Force Rosann investigators held their breath - probably the first of many times as the search continues - at the discovery of an item at one of the key locations they have zeroed in on since Monday.

The discovery was compared to a replica Spiderman suit held in the team's suite of search tools. It proved to be unrelated to the investigation.

Police continued the high intensity search at Kendall on the NSW Mid North Coast on Wednesday (November 17), with the search honing in on a patch of bushland on the corner of Cobb and Co Road, just one kilometre from where William was last seen playing at his foster grandmother's home on Benaroon Drive.

The ground penetrating radar is being used to detect any disturbance or foreign objects in the soil.

A team of experts, including an archaeologist, forensic anthropologist and a sub-surface water technology expert also visited the search site on Wednesday.

A team from the Australian Federal Police have also joined the mix.

Over the past three days police have dug part of the garden at the home on Benaroon Drive and sieved through the dirt. They also sprayed luminol, a chemical that is commonly used in homicide investigations, at the home to check for blood.

NSW Police Commissioner Mick Fuller said all possible scenarios are being considered in the renewed search.

"These areas have been searched but initially we were searching for a missing boy," he said.

"The transition of the investigation was looking at some persons of interest that were clearly not, and I think some time was wasted on that. A fresh set of eyes, under Chief Inspector Laidlaw, have been meticulously pulling apart this matter.

"It is my understanding from the investigators there is certainly one person in particular we are looking at."

Commissioner Fuller would not divulge any information that could potentially jeopardise the work of his team or reaching a conclusion in the case.

Search: Police are expected to continue the search in bushland on the corner of Cobb and Co Road over the coming days.

On November 9, the Strike Force seized a vehicle from a property in Gymea. That vehicle, it has been reported, was formerly owned by William's foster grandmother. She has since died.

The current owner of the vehicle is not linked to the case in any way.

The vehicle was taken to a secure facility where it is undergoing extensive forensic examinations and analysis. This is expected to take several weeks, a NSW Police statement said.

IN OTHER NEWS:

Over the coming days police will continue to be assisted by the NSW Rural Fire Service (RFS) to remove dense foliage at the search site on the corner of Cobb and Co Road.

The search at this site is expected to last up to three weeks as police and forensic experts meticulously comb through the soil for any evidence.

Police Minister David Elliott was asked about a report that police were investigating whether William died after falling from a balcony at his foster grandmother's home.

"With a mysterious incident like this, every single option has to be investigated, every scenario has to be reviewed and tested," he told reporters on Tuesday.

"Let's hope whatever the conclusion is gives closure to the families and community."
