No one knows 100% who killed JonBenet. But whoever did it,was very smart. When you look at everything step by step,whoever did it made sure everyone looked like a suspect. Ranson note: Addressed to John,with familiar notations ($118,SBTC,southern common sense,etc.). That could be anyoneR,BR,friend,business associate. Pen and Paper: That could be JR,PR,BR,the housekeeper,housekeepers family,friends,or anyone who ever had opportunity to snatch a pad of paper and some pens from the house. Pineapple and tea: Could be Patsy or Burke their finger prints were on the bowl. Tea,although no finger prints,could be Burke,he was the tea drinker. Suitcase under window: Enclosed with JAR's blanket (with his semen) and a book belonging to him. Could be JAR. I'm sure there's more,these are all I can think of off hand. So who ever set this up was smart enough to incriminate everyone. Very smart. IMO it was set up to steer away from an intruder..If it was a cover up by the Ramsey's to look like an intruder, it would mean they are incredibly naive and stupid. I don't think the Ramsey's are stupid or naive.
