An investigation examining the theory that William Tyrrell’s adoptive mother disposed of his body after an accident will show footage of her undergoing extensive questioning.
The boy, who was last seen wearing a Spider-Man costume, disappeared while playing on the terrace of his adoptive grandmother’s house in Kendall, on the New South Wales north coast, on September 12, 2014.
An investigation into his disappearance was reopened Monday and examined search efforts for the three-year-old boy, as well as the adoptive mother’s possible involvement in the disposal of his body.
She allegedly loaded the boy’s remains into her own mother’s gray Mazda and hid it before calling triple zero fearing another child would be taken into her care, Lidcombe Coroner’s Court was previously told.
The woman, who cannot be identified, has always denied any involvement in his disappearance.
The investigation will reach its final day of evidence on Thursday, when footage will be played of the foster mother being questioned for four hours by the NSW Crime Commission in November 2021.
In this round of evidence, the fifth of the long inquest, coroner Harriet Grahame heard from police officers involved in the search for William and an analyst who identified possible persons of interest.

A truck driver who was in the area when William disappeared spoke of the cars he saw at the time, but offered no new clues.
They have also given expert testimony on how rainfall and flooding can displace human remains and the preservation or disintegration of bones in the environment.
No one has been charged in William’s disappearance and a $1 million reward remains for information.
A decade-long investigation has involved hundreds of persons of interest and dozens of searches.
