My thoughts:
The cars we parked in front of # 35, the FFC said she saw no one in the cars, maybe the occupants went inside # 35 ( the house is set a fair way back of the road ) ?
The person that the FFC said she saw turn into the Miller's fits the description of DP and also maybe FA , both have access to may cars on the Heron Ck propery...........
DP & FA know each other very well, DP says he's scared of FA
The Miller's was essentially vacant (as the Miller's were away) was someone hiding there as a lookout??? To tip someone off, maybe in car? I'm sure PS would have known the Miller's were away, he seemed to know everything about everyone. He knew the FF arrived the night before , heard the kids that morning etc
FA has a history of dragging people into his crimes than holding that over their heads so to speak. He brags to anyone & everyone it seems about getting of murder charge.
Seems people are scared of him.
I am stating to wonder if WT was initially taken to Heron's Creek ( hence the searches ) & than driven away ( maybe 300kms somewhere ) on another day?
It was not made clear in evidence, that the day RP said he picked up FA & WT at the shed near the school that it was the 12th, I think many assumed it was, maybe it wasn't? Maybe it was the next day?
Evidence was heard that FA used cars from people without their knowledge ( from DP from memory ) despite having no license.
I think there a few people involved in this crime
I think poor William was eventually placed in water due to alot of questions around boats & fishing
PS may have seen something or knows something, he could have been threatened or his family, but with FA know locked up ( he won't live to get out of jail ) , this his his time to speak up , but he hasn't ( that we know off )
ALL IMO etc.
