GRAPHIC
I'm not seeing dismemberment occuring in the bedroom. In my mind, her body was taken and laid out on the bathroom floor for this task, and then the parts tossed into the bathtub as they were removed. When I saw the cut marks diagram from the autopsy, the first thing I did was go to my bathroom, and stand over my tub. I tried to make sawing motions from this angle. Can't be done. Try it, and you'll immediately see what I mean...your arm is at an impossible angle when you try to "saw" the side of the bone closest to the edge of the tub.
If we look at the pictures of the bathroom, it's easy to see that the bulk of the blood evidence was found in this room. The entire floor is missing, along with the vanity and sink. And, to my mind anyway, it is painfully obvious that the paint job in this room was rushed. It doesn't go all the way around the room, doesn't go all the way behind the toilet, and there are black brush strokes on the tank of the toilet. Ask yourself...would YOU leave a "finished" room of your house like this?
My gut feeling is that the murder occurred in the bedroom, the dismemberment occured in the bathroom, and the clean up of the cleanup occured in the kitchen. Part of the kitchen floor by the refridgerator has been removed. My first thought when I saw that was that a trash bag leaked. That's still my gut feeling, although, I have nothing to base that on other than gut feeling.
