Hello, I think you need to look at motive. And also to remember that this was a premeditated crime. (Also the Burke and Patsy theories are not medically sound. We know that JB was already dead when she received the head injury, which is why there was almost zero internal bleeding.)
So given that this was a premeditated crime, as a woman, I do not want to give John or John Andrew (at least one is a sexual abuser) a free pass, and blame Patsy or Burke. It's also worth nothing that if Patsy or Burke had accidentally killed JB (which is not medically sound), the family could have claimed that the little girl fell and hit her head.
It's important to remember that John and John Andrew WANT us to believe that Patsy and Burke committed the crime, which is has been not possible due to medical evidence.
So, since it was a premeditated crime, we must look at motive:
1) To silence JB so that she could not report PRIOR sexual abuse, including what may have occurred on December 23, 1996. (And fibers from John Andrew's EA device were found in JB's bed; not sure if they were also found in Burke's bed.) The police were called on December 23, 1996. However, the person who opened the door said that the police had been called by mistake.
JB was intelligent, articulate, and outspoken. Had she reported prior sexual abuse by John or John Andrew, she would be taken very seriously. Had Burke reported prior sexual abuse by John or John Andrew, he would not be taken as seriously. (I believe Burke was autistic.)
Therefore the MOTIVE to silence JB so that she could not report PRIOR sexual abuse is stronger than any MOTIVE to silence Burke.
2) To frame Patsy, or at least to discredit her. Obviously a judge or jury would not convict Patsy, but she was discredited and disgraced. People were willing to blame Patsy, claim that she killed JB by accident, and yet give John or John Andrew (at least one of whom is a sexual abuser) a free pass. Talk about sexism and bias.
There was an obvious MOTIVE to frame Patsy: ransom note included some of her expressions and choice of words. Also Patsy's notepad and writing pen were used. Patsy's paintbrush was actually used to strangle JB. (JB died from strangulation, and was already dead when she received the head injury). Now, if Patsy herself had strangled JB (and we know that she did not do this), she would have the intelligence to hide or throw out the paintbrush. (And would Patsy write a note to incriminate herself? She was an intelligent woman.)
Patsy's items that were used: paintbrush, notepad, writing pen. Plus the ransom note cast suspicion on Patsy.
What motive would John Andrew have to frame or at least cast suspicion on Patsy? He would want his father to reunite with his mother, NOT because he cared if his parents got back together, BUT due to John's WEALTH.
Therefore, John Andrew would have the above two motives. Remember that John Andrew's suitcase was found near JB's body. The suitcase contained a semen-encrusted blanket (semen belonged to John Andrew), a children's book called Dr. Seuss, and some other items. So, why was the suitcase near JB's body? Because someone (likely John the father) had every intention of disposing of JB's body, but also of disposing of the incriminating suitcase.
As previously mentioned, fibers from John Andrew's EA device were found on JB's bed.
Lastly, there has been some suspicion that JB told Melinda (her older half-sister) about the sexual abuse. However, I like to think that Melinda would have done the right thing, and reported this to police.
I believe that John Andrew also had a key to the house.
You need to also ask why John the father was not framed for the crime - only Patsy the mother!
And let's use common sense: a routine "sexual predator" would be more interested in framing the father than the mother!
Respectfully, while you raise some interesting points here, I do disagree that the murder was premeditated. If it had been, I would think that they would / could have done a much better job of covering it up. Instead, it was a jumbled, chaotic mess that made little sense and had to rely heavily on LE making a lot of mistakes early on and throughout the investigation.
I do agree that JB was being molested, and it's very likely that BR was too. It is my belief that this was a pattern of behavior for JR that may very well have been a reason, if not the reason for the divorce from wife #1. Of course there are also indications that he cheated on Lucinda. The whole scenario with the first daughter Elizabeth and JR's seeming obsession with her leads me to think that she was also molested. And I think that perhaps JAR was being groomed in his father's footsteps. I think BR may have been too young at the time to be groomed, but there was definitely something going on there and I'm betting that grooming may have been in his future. The bed wetting by both kids seems to point to abuse. And in BR's case, his history of scatolia certainly points to issues.
I think that JR was a very smart and manipulative man who may have gotten in over his head with certain associations in order to promote his business aspirations and fit in with the Boulder community. Witness accounts from various persons who worked for the R's in the house report that he was very caught up and preoccupied with his work. He was absent a lot. We also know that PR was very ill for some time and for her immunity had to be isolated from the rest of the family.This likely put a lot of strain on the marital relationship. And it also meant that when JR was home, time spent with the kids would have been without PR around. Opportunity.
At some point PR's cancer goes into remission and she is back spending more time with the kids, at least JBR. I found interviews with the housekeeper very interesting as to what the family dynamic was at that time. She describes a household busy with activities for the kids, this is the period that PR and JBR become really involved in the pageant stuff. BR has a good circle of friends and he spends a lot of time hanging out with them. JBR does not have that many friends, although she is described as the most outgoing. She occasionally sleeps over at Daphne White's house (Fleet & Priscilla's daughter) but JBR never reciprocates with Daphne or anyone else with a sleepover at the R's house. The relationship between JR and PR is described as distant, almost transactional. As if PR were more like a secretary than a wife. And while the relationship between mother and daughter has been described as "close", I see some signs there that point to that not necessarily being true. PR had definite ideas about how she wanted things to look to those looking in on the R family. JBR had a bit of a rebellious streak and was starting to exert herself more as to what she wanted to wear, regardless of what PR thought she should wear. PR at one point admits that JBR is really a tomboy at heart, the whole pageant thing was PR's attempt to regain those days when that was her thing, and it feels very much like it was somewhat forced upon JBR. It would be interesting to see had she lived, if she would have started to push back on that. But I digress. I think that PR at some point must've guessed that JR was abusing at least JBR, but she didn't want to rock the boat and lose her breadwinner or her societal status. So she kept quiet, as far as we know. But all of the doctor visits for JBR must have been at the very least troubling, if not a big clue. I very much doubt that JBR would have said anything to PR about this. I also doubt that JBR said anything to Melinda. Melinda has been very adamant about defending her father and her family. And she does seem like the kind of person who might have tried to do the right thing. Perhaps this is why as I believe, she did not share the same experience as her two siblings ER and JAR.
I do think what happened to JBR on that fateful night was accidental. And I think that JR had let someone else in the house that night and whoever this person was /is most likely went overboard with EA. Panic ensued and they initiated the cover up. PR at some point became aware, perhaps by JBR's scream that a neighbor heard. She would have been furious, but also recognized the need for a cover up. JR likely to a certain extent blackmailed her into writing the RN along with assisting with the cover up. And while the RN absolutely points to PR and to some extent incriminates her, some of what is said in the note also reveals an anger and contempt for JR. They staged JBR's body in the basement along with the suitcase. An interesting side note is that the Dr. Suess book that was found in the suitcase is actually a book written for adults, not children. It would be interesting to know if they were aware that the book and the blanket with JAR's semen on it were in the suitcase. JAR most likely did have a key to the house, but it was proven that he was not in Colorado when this occurred. By the time of the murders, JR and LR had been divorced for almost 18 years. She had remarried. I doubt very much that anyone was under any delusion that JR and LR would reunite. Both MR and JAR enjoyed time with JR and he was not neglecting them financially. And very doubtful that he would leave them out of any will. Getting him back with LR would serve no purpose.
If JR had intended to dispose of the body, why didn't he? He had all night in order to do so. More likely the suitcase was planted there to look as if the "intruder" needed it to help climb out the window, or for that person to dispose of the body. But why didn't they? Instead we are to believe that the "intruder" after killing JBR takes the time to pen the ridiculously long RN, putting themselves at more risk of someone waking up and finding them there, leaves behind the note and the body, which surely he would have taken and disposed of if he really wanted $$$ for a kidnapping. It makes no sense. If that was premeditated, someone didn't have their thinking cap screwed on very well.
There is also still debate as to when the head injury occurred. There was internal bleeding found, so the experts disagree as to if the blow to the head came first or after she was strangled. What makes the most sense to me is that she was struggling with her abuser(s) and she screamed. She then was hit in the head to subdue her and shut her up. I don't think it was intended for her to die. JR and PR wanted to continue to play perfect, happy family. But playing with EA is dangerous, especially with a child.
Patsy wasn't framed, per se. But JR made sure she was implicated because he knew that LE would look at the parents first. He wanted to make sure she stayed team JR instead of turning against him. And he rightly judged who she was because she was much the same as he was.....more concerned about appearances and maintaining social status than either one of them were about the lives and well being of their own children. Ironically, in the end it all backfired. They put themselves under suspicion by refusing to cooperate with LE, didn't listen to the advice of friends who told them they needed to cooperate, and threw all those friends under the bus thereby ensuring their own ostracization from that very society. The business had to be sold, the money and privilege were gone.
I want to underscore here that this is just my opinion. Obviously everyone has their own opinion about what happened and who might be guilty or not.
