To your point about the dirty underwear, PF, and also txsvicki's to which you replied...
I have a five-year-old son and almost every pair of his underwear has poo stains ("skid marks") because he struggled with proper wiping. For awhile we were buying new packs of underwear on a very regular basis. To resolve it, we would have him call to us when he had a BM so we could coach him on how to do it properly (usually we didn't wipe him, just instructed him). The bigger issue we had, despite our efforts, was that at day care and preschool they never checked or noticed since he was otherwise fully potty trained. So he'd go there in clean undies and come home with stains. I didn't address it with the day care staff because I didn't want my son to be embarrassed or have them wiping him at that age.
Additionally, our son still wets the bed from time to time. There was a two-week span when I went back to work after having our second child when he (four-years-old a the time) wet the bed almost nightly, and I attributed that to him feeding off of my stress and experiencing his own with all the recent changes in our lives. Otherwise when he does it, he says that he woke up that way, so I figure that his body doesn't always wake him when he has the urge and he will get there in his own time.
As a parent, it's hard not to get frustrated over toileting issues like these. I do my best to be sympathetic and supportive instead of punitive, but no one's perfect. I'm sure I've inadvertently made him feel ashamed about it, and the thought of that makes me incredibly sad. It sounds to me like PR was not as tolerant. There were steps she could have taken to help matters but, selfishly, she did not. The books she had worry me that this issue was looming large for PR, that she saw it as JBR's issue solely (as opposed to one that she contributed to), and it sharply contrasted with the picture-perfect public image of JBR that PR worked so hard to project. Then again, there are many aspects of this case that are equally troubling.
I recognize that toileting issues at JBR's age can have many different causes, including sexual abuse, but toileting issues are also a normal part of potty training and childhood development. The parents' handling of them has a tremendous impact on potty training success and the child's psychological well-being. If JBR was severely punished for accidents, that may have prolonged and intensified the otherwise typical toileting issues she experienced.
The following article is outdated (1993), but offers valuable insight into child abuse stemming from toileting issues (warning: very sad read):

After reviewing so much evidence in this case, the only theory I have found to fit all of the otherwise confounding puzzle pieces together is that JBR had an accident that night, PR accidentally murdered her, and then staged a cover-up with evidence that pointed away from their house, their family, and her motive. I believe that PR had been physically abusing JBR prior to that night, both by hitting and cleaning her violently. The violent cleaning would be inside her vagina with a wipe and/or douching, both of which would explain the vaginal trauma that night and in prior incidents, the recurring vaginitis, and the pediatrician's interest in JBR's sexual development. Further, the recurring vaginal trauma and the incident on the night of JBR's murder were described as
not likely to be sexually gratifying and also not torturous, which has always been an issue for me when sexual abuse is discussed as a motive.
A little more on the doctor visits, which is also discussed in this thread: Although it's common for mothers to accompany their children to doctor visits, it's not common to be at the pediatrician 33 times in three years for reasons including vaginal infections and facial bruising/abrasions. If PR was the abuser, she would insist on accompanying JBR so that she could hide the visits and treatments from JR, plus she could be there to explain her version of events to the doctor. It also didn't seem like PR was particularly concerned about the excessive doctor visits or the reasons for them, which makes sense only if PR knew the true cause.
Much of this is pure speculation on my part, but again, so far PDI is the only theory that makes all of this mess make sense to me. I have just begun reading Kolar's book and am interested to learn his perspective on BDI, and I'm open to alternative explanations as well.
Unfortunately I don't believe that we will ever know what happened with 100% certainty, but by reviewing the evidence, seeing how that evidence fits in to different theories (or doesn't), and sharing our findings, I think we can at least expose the person(s) responsible for the record. I hope that someday, in the absence of the ability to prosecute, the BPD or DA can, without political or financial influence, at least issue a statement of their professional opinion with regard to every last piece of evidence uncovered in this case...but I'm not holding my breath.
