otg,
Your theory is thought provoking- thanks for sharing it.
I've grown to believe that the most probable explanation is that Burke, somehow, someway, caused the death of JonBenet. In reality, this is a very complex and confusing case, with no truly logical solution. The ransom note alone proves the "crime" was staged, and that there were never any kidnappers. The behavior of the parents-especially Patsy-was bizarre and instantly led investigators to suspect them.
Nothing in the record indicates that Patsy was anything other than a doting mother, who cherished her little daughter. Nothing indicates that John was anything other than a typical powerful businessman, who was probably distant and perhaps unaffectionate with his children, but was not sexually abusing JBR. Of course, there has to be some explanation for all those doctor visits, usually centered around JBR's vaginal area, as well as the statements by Cyril Wecht and others that there was evidence of chronic sexual abuse. Could Burke have had a long, recurring "problem" in this area? Was he part jealous, part attracted to his beautiful little sister, who clearly was the "star" of this family?
I think the answers to what happened that night lie in a few tantalyzing tidbits in this case. The first one is- what were the details of Burke "accidentally" injuring JBR with a golf club, previous to the murder? Was this a huge red flag, ignored by indulgent parents who were in denial about a potentially explosive sibling rivalry? The second one is- under what possible scenario did both the terrible head injury, and the strangulation, occur? Like the kidnapping/pedophile combination, these two simply don't go together. If she was strangled-accidentally or otherwise-why was she hit so savagely over the head afterwards? Can we imagine any parent doing that to their child? On the other hand, if she was hit on the head first-accidentally or otherwise-why bother to tie a rope around her neck afterwards? Again, can we really picture even an eccentric woman like Patsy thinking of such a thing, let alone actually doing it? The third is- the mystery of the oversized underpants. This is so bizarre that I find it almost impossible to fit it into any scenario. Still, Patsy clearly was evasive about this issue, and there is no logical reason for JBR to have been wearing them.
Burke's reaction to his sister's death-at least what little is publicly known about it-is perhaps even more incomprehensible than Patsy's or John's. He displayed no curiosity, let alone sadness or any emotion at all, as he was led out of the house (again, an act which makes sense on the parents part) and his answers when questioned later were alarming. As I recall, he seemed more interested in the video game he had than in his sister's murder, and said something like "I'm moving on." There have been intimations that Burke had some kind of perhaps autistic/aspergers syndrome, but in reality we know very little about him. It's a real shame that he apparently refused the recent requests to be questioned by police about the case. Like his parents, he seems intent on not providing answers, which of course only arouses more suspicion on the part of internet posters like us.
Well, I've rambled too long. I do think that otg has offered up a reasonable scenario. Not saying I buy it, but unless John or Burke ever really talk, that's probably the best any of us can do.
