William Tyrrell's foster mother's eerie last comments she made on 60 Minutes

In an interview just months after William Tyrrell mysteriously vanished, his foster mother revealed she heard the boy playing on the deck, making a roaring noise. This is the alleged chain of events NSW Police has put to the Director of Public Prosecutions in recommending charges be laid against William Tyrrell's foster mother over his disappearance. William Tyrrell's foster mother is waiting to see if the DPP will charge her with perverting the course of justice and interfering with a corpse in the wake of her three-year-old son's disappearance Police claim the foster mother, then aged 49, drove her mother's Mazda hatchback from her Kendall home on the morning William vanished Senior police alleged in court last year that the foster mother 'knows where William Tyrrell is' and how his body was disposed of after he vanished from the Benaroon Drive house The old 'abduction' theory The scenario first outlined at the unfinished inquest into William's disappearance a few years back had the hallmarks of a dark fairytale. What detectives believed before: * William, three, was snatched by a 'complex' stranger from the yard of his foster grandmother's home on September 12, 2014 * William was then, presumably, at some point, killed What cops believe may have happened now: * After working through a long list of persons of interest, police believe that William, three, may have suffered a fatal accident, such as a fall from a balcony, at his foster grandmother's house *His death was then allegedly covered up by his foster mother Detectives Sean Ogilvy and Andrew Lonergan with scientist Jon Olly at the Batar Creek Road dig where they believe William's remains lie Questions have been asked about the time stamp on the photo taken of William Tyrrell shortly before he disappeared in Kendall NSW in September, 2014 Just before 9am, the foster father left for the nearby Lakewood shopping centre, seeking a better internet connection for a phone conference with a Queensland real estate company.
