7. They showed an unconcerned attitude toward their children by having the alarm system off; the kids' rooms on another floor so they couldn't hear them.
8. (Added by Eagle) They showed improper lack of concern by wanting to get out of town, leaving the body lying there until the m.e. removed it at 10:30 that night, and by "covering for" the real situation, whatever it was. In fairness, possibly pedophiles from a too-powerful secret organization of some kind, they didn't want to be the only ones standing up to until they're caught for something else. For instance, although they hadn't been Christians very long, they could have known there's a mysterious malicious "babylon" underground that rules kings of earth, a leader I'm sure isn't Bin Laden who walks in the way of Cain, "hence" jealousy of the Ramseys, pretends to be religious but is spreading hatred in the house of his God, for instance claiming that people "brag". In one part of the Bible he's called "the little horn with the bragging mouth" himself, older translations, so is projecting own guilts. I hear he's trying to take over churches by telling them children have to be taught to be humble, but Christ said they're already examples of humility, and they're going to make them too inhibited to succeed in a rough world, no resume' statements, and like that. A danger like pedophiles, don't know if he is one.)
B. Intruder Theory:
1. Lou Smit's presentation of how a man could enter through the basement window was convincing.
2. The suitcase found near that window with a shard of glass on it.
3. The unknown male dna found on JBR.
4. No alarm system on means they could have easily got in.
5. Brutality of the garotte points against parents or brother committing this crime for any reason.
6. Still looks like her size 6 panties she was wearing are not accounted for; i.e. killer took them
7. Ransom note actually makes the parents look more guilty so why would they bother with it
8. Parents if they killed her had ample time to spirit the body away and dump it. However, parents if they accidentally killed her would have called 911 immediately. The body itself points to a killer who was obsessed with her, planned to take her either dead or alive but panicked and thought he had to get away fast.
9. (Added by Eagle) All of the above plus a lot of other points I thought of until actually getting this far into writing them down, may want to add them later. But I don't think the suitcase has anything to do with the case, since FW put it there and picked up glass off the floor to put on top of it, unless having the blanket and book in it was staging pointing in yet another direction, JAR, instead of the parents. They wouldn't have done that, or killed Helgoth and staged that crime scene too, with the stun gun, boots,etc. He was shot from the left, remember, but was right handed.
I think the case is too confusing, and will never be solved. Whoever did it committed the perfect crime.
