My theory is that Burke killed his sister, either accidentally or on purpose in a jealous rage. The Ramseys, in order to not lose their son, and now last child, to a lifetime of institutionalization, concocted the stupid ransome note and kidnapping story. That would explain their strange behavior on that day. It mirrored my own families' behavior whenever my brother would get in trouble with the law, even as young as six years old.............
Have we any evidence that Burke has turned into a sociopath?
No. He's a kid in college now.
Your theory is the same as my theory has always been. Little brother may have had a bit of jealousy at all the attention that little sister always got. Who knows what happened? Maybe he accidentally killed her & mother found them. A mother would want to cover up for her child & thus the long rambling letter - trying to direct suspicion to an outsider & not someone in the family.
This is the only scenario that is anywhere close to logical in my mind.
Hadn't the Boulder County DA ruled out Burke as a suspect because they said that he didn't have the physical strength to strangle JonBenet?
I thought I had heard or read that somewhere.
I've always thought that was an interestng theory. I can't imagine anyone else the Ramsey's would cover for. And he's been in virtual seclusion since then. But I still think it was an accident initially.
It would also explain something seldom talked about in relation to the Ramsey case, but which is extremely important. All the experts in criminal behavior say that people (almost always male) who kill due to psychopathic sexual reasons, never stop at one killing. They tend to kill serially, working up to more and more frenzied perversions during their killings until they are stopped. While some details of their methods vary from crime to crime, their fundamental choice of MO does not vary, because such killers tend to be ritualistic. It's a pattern seen over and over again with such killers going back to history's first recognized sexual serial killer, Jack the Ripper in 1888.
Whoever killed JonBenet either was a sexual psychopath, or someone who wanted to make the murder look like it was committed by a sexual psychopath. Given that no other murder has occurred before or since which bears the same MO as the JBR case, I think it's safe to say the second alternative is the most likely. The sexual psychopath aspects of her murder were, in all likelihood, staged.
That would make sense, but it's hard to imagine a 9-year-old committing such a brutal murder.
And what about DNA? Supposedly Karr's DNA didn't match... what? DNA found at the scene? Wouldn't the family be ruled out by now by DNA tests?
What about the DNA found on JonBenet? It wasn't from any of the family members.
