HarmonyE,
Like you I have made attempts to peel back the layers. As Mark Beckner once said, there is no smoking gun. BR rose to the top of my list of 3 after Kolar's book and his appearance, but I dont know that his Dr. P interview gave me much except to note his pineapple stumbling, his lack of appropriate affect and his departure from statements hed previously made. (Both parents varied their explanations too, so in that regard, he is a chip off the old block.) But since you wondered about motives within the JDI and PDI theories, I had a couple of comments to add.
JDI theorists havent been present on the forum for some time. The former poster DocG has his own blog or forum, and there are a number of posters on his forum who believe his interpretation, that JR wrote the note and had been gaslighting Patsy for so long, that he thought he could control the situation. However, she found his note and called 911. I dont personally agree with his theory. But there once was someone, Ann Rule, who had an interesting derivative of his JDI theory.
Ann Rule, famous true crime author (acquaintance of psychopath Ted Bundy), chose not to become involved in writing about the case for a couple of reasons. The primary reason was that she believed these high profile cases are rarely successfully taken to court and prosecuted. When pressed on a theory she stated she believed JR had been molesting his daughter and that JB was beginning to talk, or had begun to show signs to the outside world that she was being molested. In Rules theory, JR was responsible, and PR helped cover it up writing the RN.
Btw, for any of these family involvement theories, Ive researched a bevy of women who chose the action of cover-up or concealment of family secrets/crimes, and its more common than one would think. Regardless of the various theories here, it seems the old saying that one cant tell a book by its cover has to be a truism begun in the annals of family secrets.
