The rolling updates on the William Tyrrell case continue… Yesterday’s developments: his foster parents have been charged with the common assault of a child. They will fight the charges and say the child was injured in a fall from a horse, reports this morning say. An apprehended violence order was taken out against them by NSW Police, and William’s 11yo sister was removed from their care this week. Reports also say the children’s foster mother has emerged as the one person of interest in William’s disappearance in 2014. And there was confirmation police have seized a car that used to belong to the foster grandmother, who died last year. Police are said to acknowledge that what they have so far is insufficient to lay charges over William’s disappearance, and collecting more physical evidence is vital.
