I'm inclined to agree w/ you,esp. from the position of the wound,that indentation at the back of her head appearing to be from being pushed or shoved,or perhaps thrown into something,I just wonder what caused that.
Solace pointed out something (I think she said she had some experience w/ her son being injured by someone), and that led to her thinking that large circular type mark on the front of JB's neck was a thumb print.That sounds very logical to me.Dr Spitz says she was manually strangled by a shirt collar,so if Patsy had her collar twisted,her thumb could have been there at the time,and it could have left the mark,occurring as she was pushed or shoved into something..maybe it would take that much force to leave such a mark? I don't know.
In PMPT,it says her body was tented and a glue type substance was sprayed on to check for fingerprints..and they only found one.But I don't think it says who's or where it was.Also...why no other prints? she must have been wiped down pretty well.no intruder would have done that,he'd have been in too much of a hurry to get out of the house.
The only thing I question is the WHY of it..was it really a soiling issue that set her off,and was it really unintentional? Was JR caught molesting her and that set her off? He did try to account for his underwear fibers possibly being in JB's room in DOI (IMO),although that could have come from an incident prior to the night of the murder.I do tend to think he was molesting her.
And I also wonder if he was the one who did the ligature strangulation.I think he made the garrote and tied the knot,and did the wrist ligatures.If so,then he's just as guilty,unless he thought she was already dead? I think the vag. wound was done by him as staging,although I think it's possible she was molested prior to that as well,only no injury occurred at that time.JMO.
