And this is rather odd considering the autopsy report states a definite neck furrow....
I cannot copy and paste perhaps because they are academic papers, but Google "post mortem appearances in hanging".
Apparently, the absence of petechiae is unusual, as is the presence of a noticeable neck furrow.
Medical consensus seems to indicate that the longer the deceased in hanging, the deeper the furrow. Often, when the body is discovered quickly, there is little or no ligature furrowing. SB was allegedly not left alone all that long.
And, the fact that there was no fracture of hyoid bone is suspicious.
I gotta say I wasn't all that suspicious about SB's death, but after reading the autopsy report, I am of the opinion that either her "hanging" occured post mortem, or that she not being checked on at all and was hanging in her cell for much longer than reported.
Again, this is just my interpretation after reading 4 separate scholarly articles on hanging deaths. I got no doctorly trainin'.
