ok, I've been doing some back reading, and this is something I noticed. The woman who claimed she heard the scream, woke her husband up, and He was the neighbor who reported the metal on concrete noise. I couldn't find where he had been discredited, so since his wife is the one who woke him up, IMO, his story lends credence to her original statement. I mean, what are the odds that she woke up for no reason, imagined a scream, but then he heard, the late night metal on concrete noise? Also, another neighbor noticed the flashlight lighting, and another neighbor noticed a sunroom light turned off, for the 1st time ever. So, when all of these statements are put together, the neighborhood noticed a lot of unusual goings on that night moo.
OK, but how does this help solve the crime? Let's say that a scream was heard (It was apparently more than "negative energy") and it was someone in the Rs household who made the metal scraping on concrete noise. Now what?
How do we know it was JB who screamed? Even if we assume it was JB, so what? What do we do with that info? Why did she scream? Because of what was done to her vagina? Because she saw the golf club coming at her? Because the garrotte was being very slowly tightened which scared her but still provided her enough breath for a final scream? Because it was the first time she'd ever seen a grown man's penis enlarged by sexual excitement? Because Burke was threatening her with his knife?
What made the scraping on concrete noise? Moving paint cans, or something else? Who did it; PR, BR, JR, the intruder?
As far as we can tell, the scream fits any scenario -IDI, JDI, PDI, JDI/PDI, BDI, and any other I may have omitted. It can just as well be left out of each and every theory.
It may be interesting to speculate on why JB screamed. It may be interesting to speculate on why the paint cans were moved. But none of it actually assists us in solving the crime. People feel obliged to weave the scream into a scenario so we end up getting questionable notions such as - she was clubbed in the head to silence her after she screamed. Why not just place a hand over her mouth?
