Do you really think so. It just seems so strange. The Pm report said Jonbenet died from garroting, not even strangulation. Someone had actually constructed a garrott to use on the child, that seems such a bizzare thing for a parent to suddenly do, so premeditated, yet according to the PM she did not have old bruises or signs or abuse or neglect. Why would a parent suddenly decided on Christmas day to duct tape their child up and then garrott them, and then hit her on the head after the garrotting. Garrotting, especially using something constructed for it, does not sound like a crime committed in a rage, just slow hatred. How could a parent suddenly do that? What happened, was she a favourite of one of them in particular and it was done in hatred of the other parent?
Oh yes, I definitely think so.
The things done to JBR are strange and cruel and weird and shocking no matter who did them. No use thinking it's more/less likely to be the parents/intruder based on what was done.
The best thing is to ask what's most likely. And as poster SuperDave says, it's the totality of the evidence, not any one piece.
Aside from minute amounts of touch DNA on the longjohns, there is absolutely no evidence at all of an intruder. There is no other DNA anywhere that matches the touch DNA on the longjohns. No "intruder" DNA on the garrote, the RN, or any other crime scene objects. No CODIS match after all these years. In all probability the touch DNA was transferred by the crew that took the body to the morgue, or by the coroner's sloppy procedure.
No one ever came in the basement window that night -we know because the grate was in place and the spider web was undisturbed.
There are no intruder fingerprints.
Everything used in the crime was sourced in the house.
The RN is, imo, a good match for PR's handwriting and phrasing. The RN makes no sense with a dead body being found in the basement. Real kidnappers take the victim with them. Real kidnappers might kill the victim -that is not unusual - but they don't leave the body behind when the are attempting to collect ransom at a later time.
Real ransom notes are seldom 2.5 pages in length.
Real kidnappers do not ask for $118,000 from a millionaire.
It's not a "kidnapping gone bad" whatever that is supposed to be. If the mysterious "intruder" got the girl out of her bed, he'd be able to get her out of the house.
Small foreign factions do not kill 6 year old girls, stage the murder as a kidnapping, all in an effort to show their displeasure with the United States.
The parents who are victims of a real murdering intruder would do everything they could to cooperate with police. The R's, to put it mildly, covered their asses and did not cooperate well.
The FBI predicted that the body would be found, and CASKU said it was likely an inside job.
That's just hitting the highlights, and not even all of them. As you continue to investigate the evidence you'll be more and more convinced the parents did it.
IMO the probability that the parents did it is extremely high, the probability that an intruder did it is extremely low.
