One thing that i find a little baffling is that it seems as if police didn't doorknock that Macedon area and just sniff around and generally sound-out the residents. It wouldn't have taken much to send some detectives/cops into the area and just doorknock around and ask the locals if they saw anything, maybe even do a letter-drop in the local area asking people to phone in for tips. i.e. did you see anyone sus, like, carrying a shovel lately? LOL
I think it's disappointing that they were draining dams closer in to the city, yet only a bit further out people were seeing blokes carrying shovels when apparently going for leisurely bushwalks (like, WTF), and odd vans out of place. mate, the cops could have fished this info out ages ago. This is disappointing if you ask me. Those locals would have been watching this case on tv as we all were, but they must have been thinking they were too far out to be the place were Karen was, which is why the cops should have been around there.
i'm not certain, however, that the cops didn't go that far out, but i can't remember them being in the macedon ranges. but i think people in this forum were discussing distances and projecting possibilities. thanks for those efforts, even if i couldn't really sensibly follow them because i don't know the area, good work by you guys. *pats you on the back* hehe
