Hello all,
I'm new and have a few insights to share. I'm sorry to dredge up an old thread, but I'm unable to put all my thoughts in one place due to insufficient posting privileges, so I'm finding appropriate threads to add my reply to.
I haven't had a chance to read all the replies in this thread (I did read the first one though) but I will soon. I do notice that a lot of you are going into more detain about certain injuries than I will, but I'd like to share my insights into her head injury with relation to my medical studies and experiences with head trauma.
Basically, I'd like to submit that it is of my opinion that little JonBenet was upright and conscious when she was struck in the head by the flashlight (which forensically matches the wound according to the Bonita Papers and the expert in the first post of this thread). I'd also like to submit that she died VERY soon after the head blow.
Several days ago I thoroughly reviewed the autopsy report in this area as well as the photos. It looks to me that she was strangled at least twice, possibly three times (due to the different line marks on her neck) but I can't say anything conclusively regarding that.
However, after reviewing the photos and the description of her injuries, I believe that she was upright and conscious when struck. The blow to her head came in a mostly downward direction but slightly to the right also (when facing the front of JonBenet). The nature of her injuries and the weapon used suggests that the killer was facing JonBenet face to face when she was struck.
My reasoning is the bruising to her brain, and the damage to her skull. The crown of the flashlight is, to my understanding, what caused her skull to cave in rather than crack in that one location on the top of her head. The contusion on her brain extends forward along the fracture from this location, meaning that something had to strike her head ahead of this point as well. Thus the killer was very likely facing her, holding the base of the flashlight in hand, when he or she struck JonBenet.
She was upright and conscious, and struck slightly to the right (facing JonBenet), because of the coup/contrecoup injuries to the temporal lobes of her brain. The right temporal lobe has a much more distinct contusion suggesting the initial direction of travel was to the left. Once her head stopped moving, her brain hit the opposing side of her skull with less force resulting in a smaller contrecoup injury.
However, the nature of the contusions (and the relative lack of contusions along the side, rather than the top of her brain) suggests that she was struck very much in a downward direction with only a slight cant to the right (facing JonBenet). This suggests that JonBenet must have been upright and conscious when struck, as any resistance to head movement (such as her lying unconscious or dead on the floor) would have prevented any coup/contrecoup injuries from taking place from this relatively minor force to the right (compared to the extreme downward force from the blow).
Beyond the above, JonBenet was clearly alive when she was struck, although not for long. Her contusions and hemorrhaging suggest that she was alive for a few minutes after the blow, but for no more than a few minutes. This conclusion is taken from the following observations on the autopsy report:
After reflecting the scalp, the coroner found the underlying hemorrhage and noted it was fresh and had no evidence of organization. This means the wound had not yet begun to coagulate in any form. Wounds, even devastating head injuries which tend to bleed rather profusely, begin coagulating fairly quickly after their creation.
While there was hemorrhage present, there wasn't a significant enough amount to suggest she had been alive for more than a few minutes after the injury. Again, head injuries tend to bleed profusely.
No external evidence of scalp injury was present. Girls bruise easier than boys. Children bruise more easily than adults. JonBenet would have begun to show evidence of a large contusion around the wound if she had been alive for long afterwards.
No inflammation was identified. Her brain had not yet begun to swell from the injury.
There is no evidence of inflammatory infiltrate. These are white blood cells that enter and begin to repair damaged (inflamed) tissue. They arrive fairly quickly, but were not present.
From the above, I surmise that JonBenet was struck from the front, while upright and conscious, and that she survived for no more than a few minutes after the blow. From petechial hemorrhages and other present injuries most of us have already concluded that she was alive when she was strangled and that it was the ultimate cause of death. It's clear that she did not struggle during the strangulation which would coincide with her being struck in the head and unconscious at the time the strangulation occurred.
It is of my opinion that these events were separated by no more than a few minutes, and therefore the killer had to have had the materials necessary to construct the ligature handy (or perhaps it was already made and they already knew they were going to kill her) at the time she was struck.
Super Dave, on what I'll call the other forum you suggested that you had information showing that she could have been alive for up to 45 minutes after the head blow. I don't doubt you as I'm not infallible, but I'd be very interested in seeing how they arrived at this conclusion.
