Some IDI ideas about assumptions that may be wrong.
One the most compelling clues in the case that make it seem like the Ramseys' could be guilty is the ransom note. We've all gone over the ransom note with a fine tooth comb and there are few things that make us think it points to the Ramseys.
One is that the note mentions that $118,000 and that no one could have known about that unless they were close to the family. Since the Ramseys didn't tell anyone, who could have known? However we may be making a false assumption that they didn't tell anyone. As we have seen from PRs Christmas notes, she's got a habit of listing all her family accomplishments and details. She even comes across as "bragging" to some. So it's not beyond the realm of possibility that she mentioned it to someone and doesn't remember doing so. Or a worker in the home heard her mention it. Was there a plan earmarked for that $118,000 or was it just going to be dumped in JBs account. If they had decided to use that money for a specific thing, she may have accidentally mentioned it.
Example. "Now that John got his $118,000 bonus, we're going to get that new Yacht that he wanted"
(I'm not saying that's what she said, just as an example.)
Another assumption about the ransom note that points to the Ramseys is the assumption that the note was written that night in the house on that note pad after the Ramseys had gone to bed and before they found Jonbenet. That certainly seems strange. What criminal is going to sit down and write this note risking being found.
But what if the note was written much earlier? The family had been out for the evening and there was no one in the home. What if the ransom note was written by the Intruder while they were gone. And then it was simply placed on the stairs at the end of the attack on Jonbenet.
Why do we assume that the ransom note was written in that time frame. It's entirely possible that a perpetrator sat in the house waiting for hours until they came home and filled up their time writing out this ransom note.
