I believe Bill McReynolds was the one that gave JonBenet a card that said she would be getting a special gift from Santa after Christmas, and that the card was later found in the trash. It's very possible that the Ramsey's remembered the card after they murdered JonBenet and used it as a tool to cast suspicion on someone other than themselves.
I've asked before in another post, if investigators ever asked Bill McReynolds what the card was all about, and also if he was ever questioned about the wooden harp that had names of dead children carved on it. He told someone that there was a spot left on it for JonBenet's name. I know the McReynolds were cleared in the case, but the man who kidnapped their daughter and friend some twenty years prior, also on Chistmas night, was never found either, and the wife's book about a girl being sexually abused and then murdered in her own basement, is just too coincidental, don't you think? It almost sounds like another cover up, or perhaps a "borrowed scenario" for the Ramsey's to use.
I think they're all involved in some way. Perhaps the theory about the child sex ring is more probable than we know. And what kills me the most, is how quickly the Ramsey's were able to go on with their lives after JonBenet's death. For God's sake, their daughter was strangled, blungeoned and sexually molested. I know I would be emotionally dead if something like that happened to one of my children. Yet neither parent showed any kind of emotion when describing the details of that morning, the events surrounding, and the cause of their beautiful young daughter's death. It's just horrible.
