Are you sure?
In their CNN interview, New Years Day '97, JR says he told PR to call the police.
"RAMSEY, J: Well, no. I mean, I read it very fast. I was out of my mind. And it said "Don't call the police." You know, that type of thing. And I told Patsy, call the police immediately. And I think I ran through the house a bit. "
In Death of Innocence the Ramseys write;
"John runs down the main stairs and into the back hallway. I grasp my stomach and run after him. By the time I get to him he is down on his hands and knees, staring at the sheets of paper spread out on the floor in front of him. He is examining the ransom note, under the ceiling lights of the back hall. The note reads:
(PR states what how the note reads)
"What do I do?"I stammer.
He shouts. "Call the police!"
"Are you sure?"
"Yes. Call them!"
Standing next to the wall phone, I instantly dial 911, and try to make the voice on the other end of the line understand.
So far, it looks like you're right, JR appears to have told PR to call the police. (Of course we are relying on Ramsey testimony here)
The problem is with the A&E Channel's documentary where PR states;
Patsy - "I said, 'I'm going to call the police and he said OK. And I think he ran to check on Burke. And I ran downstairs and, you know, dialed 911."'
We (or at least I) could dismiss the inconsistency in who decided the police needed to be called. Whether JR ordered PR to do it, or whether it was PR who stated she was going to do it and JR went along. Except that the physical location of the "actors" tells us something is wrong. It's more than not remembering exactly who's idea it was. In version one, JR is on his hands and knees reading the note on the floor, and PR is standing next to the phone. In version two, they are upstairs, and she runs down stairs to make the call while JR goes to check on BR.
PR has lied, at least once, about what happened. The two versions are not consistent. So inconsistent that they cannot be reconciled.
So which version is true? Did JR tell PR to call? Or was it PR's decision, one which JR went along with?
If JR wanted the call made, why not make it himself?
But of course, your objection, even if true, doesn't dispose of the problem. The police were called, with the body in the house. Why would JR tell PR to do that? Why would they try to stage a kidnapping, then call the police who will certainly find the body and realize there was no kidnapping?
So you believe that ex-Naval Officer and sharp business man JR allowed his wife and son to run around the house, staging at different times, and with different agendas? With all his training in strategy he just let everyone run around willy-nilly staging for their own purposes? I know you seem to dislike the word implausible, but I don't know what else to use here - Fantastic? Absurd? Ridiculous?
If all 3 were involved (and they weren't) then JR would be in charge, directing how things would be done. The scene, as staged would have told a single, clear, convincing story, meant to fool the authorities.
True, there is no rule book. JR could have left the body on the basement floor, hopped in his car, and took off for parts unkown, expecting the police would think it's a kidnapping case.
I'm sorry, but I must return to plausibility. If the Kidnapping is to be believed (and if not, why bother with it?) then there should not be both a body and a RN. Once the body is found, the kidnapping scenario is down the toilet.
If the body had been hidden in the crawl space we might be able to believe JR expected it would not be found there. But it was in the WC. Calling the police guarantees the body will be found and the kidnapping scenario goes down the drain.
Though there is no rule book, one might assume that any attempt to stage a particular scenario would have to be believable. Or to put it differently, there actually is an informal rule book - the scenario has to be plausible if it's going to convince the authorities. Once the body is discovered in the house it's no longer believable that there was a kidnapper. Suspicion immediately turns to the people who were in the house that night.
The evidence does not confirm all 3 were involved in staging. But we won't agree on that, so lets move on.
You have it right when you say on R (at least) sexually assaulted JBR, and an R, possibly not the same person, killed her. You've allowed, sensibly, for the possibility that it was the same person doing the abuse and killing.
