SEVERAL witnesses could not corroborate evidence given by William Tyrrell's foster mother about two vehicles seen in Benaroon Drive on the day the boy disappeared, a coronial inquest has heard.
Much of the evidence presented to Deputy State Coroner Harriet Grahame in Taree today (August 19) focused on the presence of cars around William's foster grandmother's Kendall home on the morning of September 12, 2014.
Earlier today the inquest heard a child was seen in a car wearing a Spiderman suit on the day William went missing.
The inquest heard from Detective Sergeant Laura Beacroft who was behind building the persons of interest profiles for the case.
The inquest heard Det Sgt Beacroft started working on the William Tyrrell case in September 2015 and was integral behind setting up a means for effective processing of persons of interest.
Det Sgt Beacroft worked on the accumulation of evidence sought by people who were in the area on the day William went missing, or around the period of time he disappeared.
The inquest heard Det Sgt Beacroft also endeavoured to find out information about vehicles which were seen at Benaroon Drive, Kendall the day William Tyrrell went missing.
Earlier counsel assisting the coroner Gerard Craddock questioned Det Sgt Beacroft over her involvement in the case.
In response to Mr Craddock's question, Det Sgt Beacroft confirmed two vehicles described by William Tyrrell's forster mother as being present the day the three-year-old went missing had never been identified.
During further questioning by Michelle Swift (representing the biological parents), it was revealed by Det Sgt Beacroft that William's foster mother did not mention the two vehicles in her first statement, but four days after the child went missing.
The vehicles were described by Ms Swift as being a white station wagon and a grey sedan parked in close proximity to each other on Benaroon Drive. Det Sgt Beacroft confirmed this was evidence provided by William's foster mother.
Det Sgt Beacroft also confirmed there were no other people who had reported seeing the vehicles matching William's foster mother's description, including the child's foster father and grandmother.
Earlier Mr Craddock questioned Det Sgt Beacroft over the use of the term "persons of interest".
Det Sgt Beacroft confirmed Mr Craddock's comments that a person of interest could include those not necessarily suspected of committing a crime, including family members, residents and people who might have been in the area at the time William disappeared.
The court was closed for a period on Monday, August 19.
Deputy State Coroner Harriet Grahame addressed the inquest and said closing the court was a necessity for legal reasons and only occurs when strictly necessary.
The court is expected to hear from Benaroon Drive resident and NSW SES volunteer Paul Savage tomorrow (Tuesday, August 20).
More than 54 people are on a list to present evidence to Deputy State Coroner Harriet Grahame over the course of the inquest.
Some of those witnesses will speak publicly, others behind closed doors in secret.
The biological parents of William were also present at the Taree court.
Last week the second part of the inquest concluded after hearing from witnesses in Sydney.
The inquest heard from a number of witnesses including from two former friends who told conflicting stories about whether a driver was seen pushing something down into a car footwell the day the three-year-old went missing.
The first part of the inquest commenced in March this year and heard evidence from William's biological and foster families and emergency services personnel who were on the ground the day William disappeared from his grandmother's front yard in Benaroon Drive, Kendall.
At a directions hearing for the inquest in December 2018, counsel assisting the coroner Gerard Craddock SC said it wasn't possible - yet - to conclude William was dead.
A $1 million reward for information leading to return or recovery of William still stands. It is one of the biggest rewards on offer in NSW.
