PS being lost does raise questions for sure. My first question is, where did CO get this information from? Is it credible? is it a fact?
If his wife accidently hit William as she left for bingo, [edit.... or any other scenario involving PS], did he place him in the bush behind his home, between 10.30 and 11.30. Then when he joined the search, walk up the hill and double back to where he left William and move him? How far can a man of his age walk in 2 hours carrying a 3yr old?
If he did that, why wasn't William found in the first search? If not by searchers or sniffer dogs, then by the cadaver dog. From memory of MSM footage, searchers called for the cadaver dog when they were suspicious of certain patches of bush and soil, so the dog didn't cover the whole area... please correct me if you understand this in more specific or correct detail.
The recent forensic search covered an area of a 3km radius. To have avoided the 3km search, he would have needed to have walked further than 3kms and back again. Could PS walk more than 6km in 2hrs? The search site at Batar Creek Rd was 4kms away although I can't imagine that site happened around the time of the abduction - more likely to be a later site.
Having said all that though, my thoughts keep coming back to the unidentified cars whose drivers have not come forward. Why haven't they come forward?
