When spiritual dreaming told me about it, very early in the piece, she said that it was 'straight through the forest, about 1/4km away' from memory.
I think there is also a longer back way to the property, up the cemetery road then branching off in that direction, on a fire trail or track. That is why I was super-interested in the missing car part the police were looking for along a dirt track (somewhere in this relevant part of the forest, I believe).
I don't know if it is a crime scene, but some believed that it was a possibility that William was taken first to this location. I am sure the police are onto it. It was being reported a long time ago.
I was interested in that back way too, north up the cemetery road then west to Kendall Forest border, south and then east past the house you're talking about to Batar Creek Road. Continuing along Batar Creek Road from there takes you to or past the "abandoned" house on the corner of Stoney Creek Road. The advantage would be that you wouldn't have to drive past the residential parts of Benaroon Drive. If the person didn't have a nearby base in mind, he could have stopped in the forest to assault William (but took William away with him afterwards dead or alive because of DNA).
Jennifer, yes, in this scenario I'm assuming a local person took William.
