I'm not allowed to say what I really think on here about the murder itself and events leading up to it, so you'll have to make do without my extremely interesting theories on that. Suffice to say they differ markedly from the general opinion on here which I see is increasingly driven by emotion rather than unpleasant reason.
I will say that I don't believe BL is hiking the Appalachian trail where people brush past each other on narrow paths and everyone looks into each other's eyes in case they might be alone in the wilderness with a psycho.
I think the choice of the Carlton reserve was significant though, to instill the idea that a) he might kill himself there out of despair, and b) that in doing so his body would almost certainly never be found. That might deflect the pursuit sufficient to give him time to come up with a plan. Therefore I doubt he ever went into the Carlton reserve.
I think he was giving himself a bit of time to see his family one last time and sort out some of his affairs before disappearing/killing himself, though if the latter, one might suppose he would do so in the comfort of his home rather than in a pestilential bog. Everything has certainly gone very wrong for him and as I suspect he is/was a perfectionist I'm sure that situation is/was causing him agony. The life-force will drain eventually, and I would be quite surprised if he hasn't already killed himself, and if he has, then I suspect he would be clever enough to ensure that his body would never be found, thereby leaving a legacy of mystery for ever, which would be an appealing option to anyone who has absolutely nothing left to live for.
