None of these are exact. Rigour would tend to indicate a lot, but doesn't that depend on temperature?
Was JBR moved?
:dunno:
While not exact, forensic science is extremely accurate. There are always variables, such as temperature of the body at death-was a fever present or had there been exercise that may have raised body temperature. Ambient air temperature of course, figures in. But in THIS case, even though it was a basement, it is considered indoor, or room temperature, on which the standards are based. JR also stated in a interview that one of the reasons he never rushed to repair the broken basement window which he admitted breaking was that the basement was warm, even in winter, because of the furnace.
In indoor (room) temperatures, the body loses heat at the rate of 1 degree per hour to 90 minutes. This is algor mortis. That is why the liver stab is important. And I am very suspicious as to why it was not done. Sloppy forensics were a part of this case from the first encounter with the body. It seemed all the coroner felt he needed to do when he examined her body was to pronounce her dead, not try to help solve her murder. He spent about 10 minutes examining her.
There are VERY few limited situations where the body does not lose heat predictably after death, and in some cases, the body temp even rises-one is a pontine hemorrhage (where a burst aneurism or cerebral hemorrhage occurs in the section of the brain known as the pons, which regulates body temperature, and another is the use of certain street drugs which cause a marked and fatal rise in temperature - even up to 108.
I do not personally believe JB was moved after being placed in the wineceller, as her livor pattern tells us that she was placed on her back, legs straight out, arms were NOT behind her or raised high over her head, and head cocked to the right (exactly the way her body was when she was brought up)- within 15 minutes or so of her death. The blanching phase of livor proceeds to the non-blanching phase at some point, and she was in the non-blanching (or fixed) phase when she was found.
Rigor tells us her body had not been in any other position first, at least not after 20 minutes or so of her death. See, it is the combination of the livor pattern and the stage of rigor that tells me this. While she likely died on her stomach (anterior urine stains on the longjohns and panties as well as the knot of the ligature being at the back of her neck, and the bruise on her right posterior shoulder (a perfect indication of someone kneeling or pressing against her as the ligature was made and tightened), I believe that SOON after death, she was placed on that white blanket in the wineceller.
IF she was moved at all, she may have been brought closer to the doorway of the wineceller. There was an opportunity for JR to have done this during his "missing" 2 hours (approx. 10 am - noon) when Det Arndt said she could not account for his whereabouts. He could have pulled her along the floor, or (if livor was fixed) picked her up and moved her.
