Okay, found an excellent collection of various tellings of the "accidental blow by Patsy when she found John molesting JB" story, including the sources, the players, and the polygraph claims.
The polygrapher was Gene Parker, and you can find it all here at ACandyRose.com (of course, thanks to ACR for all her unmatched online work on this case):

While I've heard this story's basic premise of the murder for many years, knowing what I now know after my own blundering through the evidence and transcripts as they've been released to us over 14 years, it actually sounds more plausible than I had previously thought.
In fact, I can't think of any evidence that refutes it. It would explain what led up to the head blow, and why both parents would cover up for the other, which has been pointed out before, but I'm a stubborn, "show me" kind of person, and until I realized the significance of the "nosebleed" questions asked of Patsy and the blood of JB on her pillowcase, I wasn't convinced that the strangulation was absolutely done by one of the parents. Now I am.
So one of the two essential remaining questions of the murder for me has been who struck the head blow upstairs and why? Of course, without that confession, without something more than a tabloid story, we will never know. But this theory does fit the evidence. Also, the fibers of John's Isreali wool sweater found in the genital area where JB had been wiped down fits this scenario, as well.
So if these allegations were true, if these people weren't all just making stuff up to cash in and/or embellishing the truth in the Ramsey case tradition of "don't tell the whole truth because it's too dangerous," that would answer the second essential question of this murder: both parents were involved in the strangulation, as well, and that's why both of them had their clothing fibers present on the body, in the paint tray, and in the strangulation knots. That would also explain why they both lied to LE repeatedly, hired separate lawyers, and were bound together in the cover up until death did them part.
And while I don't claim to be psychic, nor conclude that others are, I have long had an image in my mind of John pulling the cord from above JB, straddling her little face down body in the basement while Patsy held her down. I have never been able to shake that image. Not that it's more than just my imagination or anything....
But I do believe the evidence is clear that one of the parents straddled the child and pulled the cord from above while she was lying on the basement carpet by the paint tray; and somehow the body had to be held down to pull the cord, a counterforce to keep the body from rising and to create the tension necessary on the noose.
I've never done an experiment to determine if it would take two people to do that, considering the length of the cord, etc. I hope LE has. Surely they have...right? :no:
