I hadn't considered this idea SunnieRN, but now that I think about it, it makes sense. Maybe BR & JB did some "exploring", "playiing doctor", you know. It happens. But the more I get to understand the whole Ramsey family dynamic, it seems to me that sexual misconduct or inappropriate conduct might have been the "norm" in that family, from JAR, PR, JR, or a myriad of others. It's a horrid thought, but makes sense. And if we add the transgenerational aspect to the picture (i.e. a sexually abused child might be inclined to do it to others later), perhaps it stems back from PR's side of the tree and/or JR's. Or, sadly, both.
And as vile as sexual abuse is, it does happen, but doesn't usually lead to murder. Something else was so broken in that family that there was a snap on the behalf of one or more of the three surviving R's in the house the JB was killed. It sad for all concerned-- even sad for the one or more who killed her. (Not excusing the crimes in any way, shape, or form, merely expressing a bit of sympathy here for what must have been a painful life for all of them.)
I dearly wish we lived in a world where we didn't have to think about such things.
