I never thought of that!
Also, I see a lot of people ruling out a "planned abduction" theory, based on the fact that the trip had been moved forward from the initial planned arrival time, IMO it makes it more possible, based on the time he was abducted, they were originally due to arrive that Friday morning weren't they?
The scenario I see as most possible, is either -
Spedding arrives at Benaroon drive to carry out the repair job, perhaps in a private vehicle - sees no car - comes across little spiderman & bundles him into the vehicle with the pretence that he was looking out for the child, "begins driving the boy to the local police station or attempting to find his parents "& doesn't look back
T.J stumbles across little William while out collecting scrap metal - I read on WB some threads back that the old style otto bins were a good source for scrap metal - he takes William into the bush
Both scenarios I believe William didn't survive, I believe he is hidden out in that bush somewhere.
