Overview

• NSW Police have suspected William Tyrrell's foster mother for almost three years, but no incriminating evidence has been presented in court.
• The foster mother has consistently denied any involvement in William's disappearance and has not been charged with a crime.
• The inquest is exploring a police theory that William died accidentally and his foster mother disposed of his body to avoid losing custody of another child.
• Experts testified about the preservation of remains and materials, but no new evidence was found during extensive searches.
• A witness reported seeing a suspicious car on the day of William's disappearance, but this does not align with the police's current theory.
