"At some point after 9.45am, William was playing the lion game with his sister and had run to the back of number 48 and underneath the veranda several times.
On each occasion, he had emerged to his waiting sister with a cheeky grin.
Sometime before 10.30am, William's foster mother retreated from the outdoors inside to make a cup of tea for her and her mother.
Down the street, a man on a ride-on mower cut his lawn.
Again, William disappeared down the side of his grandmother's house towards the backyard.
Only on this occasion, the boy did not reappear.
When she noticed William was missing, his foster mother asked William's four-year-old sister where he was and then ran back to the house and asked the grandmother if William was back up there.
He wasn't and the two alarmed women conducted a further search, but William was nowhere to be seen."
