Child in a Spiderman suit seen in the back of a car the morning William Tyrrell disappeared
A child in a Spiderman suit was spotted in the back seat of a car the morning William Tyrrell disappeared, the coronial inquest into the little boy's mysterious disappearance has heard.
Kendall local Ronald Chapman told police he was outside his home and was confident he saw a little boy pressed up the back seat of a car's window in September 2014.
Investigations by Strike Force Rosann have not turned up any information about whether or not the boy was William, who disappeared while playing on his foster-grandmother's front verandah on Benaroon Drive in Kendall.
Detective Sergeant Laura Beacroft told the inquest in Taree on Monday Mr Chapman saw what appeared to be two cars driving in tandem down the street, with the boy in a car “driven by a woman”.
Mr Chapman was "quite a well respected gentleman in the area", counsel assisting the coroner Gerald Craddock said.
"Alerted by some noise, he went out the front of his place. He saw a vehicle drive out of Batar Creek Road [off which Benaroon Drive runs] and saw another vehicle behind that one which was, to his observation, possibly driving together with the first vehicle," he said.
"In the first vehicle, in the rear of the 4WD, he believes he saw a small boy who was standing at the rear curb side window as the car went past him and to his observation that boy was wearing a Spiderman suit.
"Police investigated that series of recollections. The car has not been identified, there was a boy associated with one of the other houses in the street who had visited around that time and who did have a Spiderman costume. But detective Beacroft's assessment was that it wasn't that other small boy who happened to have a Spiderman suit."
Det Sgt Beacroft told the court she didn't believe Mr Chapman was making it up.
The inquest was also told on Monday that more than 400 "persons-of-interest packages" were created as police tried to identify and interview every person who could have taken William.
Officers spent months interviewing hundreds of the 1140 people living in the mid-north coast town with a list of set questions before making more targeted inquiries with so-called persons of interest.
Acknowledging "person of interest" wasn't an official term used by NSW Police and had no settled definition in policing worldwide, Det Sgt Beacroft said those on the list included neighbours and people living in nearby streets.
"It was a very low standard to meet in order to become a person of interest," she said.
Residents were also asked to detail all deliveries and repairs to their home over a one-year period.
The inquest will hear from Mr Chapman later this week in Taree Local Court.
