“After a couple of minutes,I thought,‘Oh he is quiet’,” she said in a statement.
When she went to check on the little boy,who had gone around the side of the house as he played,he had vanished.
William’s foster-mother’s version of events is under new scrutiny,after she emerged this week as the sole person of interest Strike Force Rosann is investigating.
Police Commissioner Mick Fuller confirmed that there was only one person detectives are looking at.
Detectives are investigating whether William fatally fell from the second-storey balcony of the Kendall home,and have spent the week digging up and sifting through the dirt of the garden below.
Police believe that a Mazda 3 seized in southern Sydney and that previously belonged to the foster-grandmother may have been used to transport William’s body to nearby bushland.
