oops..you're correct--Panda...I guess my gut thought on this case from the beginning is that it was a premeditated and a planned murder---and, I inadvertently wrote and attributed that statement in my summary to Detective Stamper--because everything else Dectective Stamper said, I agree with except that aspect...Thank you very much for pointing that mistake out.
No worries trujac. The only reason I pointed it out is because other people who don't read all the articles then believe it as fact, and it becomes Chinese Whispers.
I honestly can't decide what I think happened. Logically, it would make sense that they were using the drone which became lost in the bush and then set out to retrieve it and became lost, killed by wild dogs or severely injured. However, it's a big coincidence for their tent to happen to go up in flames and for both of them to be missing. Especially given all the reports that Russell never strayed far from camp. I also can't believe that someone as "experienced" in the bush and who knows the area would get lost. I always carry a map and compass so that scenario is quite foreign to me. At the very least, you would think he would know how to read the lay of the land - the topography.
Then there is the premeditated scenario. I wondered if someone found out about their affair and took exception to it. But there's no evidence of anyone visiting the campsite, either on foot or by vehicle. For this theory to work, it would have to be quite an elaborate plan, with knowledge of where Russell camps. Given the area is so vast, the people concerned would have to either have followed him or drive around in the "hope" of finding him and Carol camping together. For those reasons, I tend to discount that theory as somewhat "out there".
The other scenario I thought feasible is if they were using the drone and it pissed someone off big time. As there's no evidence of anyone visiting their campsite, that would mean this scenario would only apply if they were away from their campsite. Perhaps a campsite next to them. Given the comments by various people who knew Russell well, it is extremely unlikely he would leave his vehicle and walk a massive distance, so whatever happened I believe must have happened fairly close to their campsite. But then again, if he chose to lock his vehicle, that to me would indicate that he had the intention of not having his vehicle in his sights.
As far as the running off together scenario, I don't think that works at all.
