Just wondering about the boots if say 50 pairs of the same boots was made could you go by the fibers from a different pair or would it be different since that pair never been owed by PR..
Here is how that would work...
IF the beaver hairs were to be sourced to PR's boots- forensic specialists can only say that the hairs are CONSISTENT with the fur from that specific make and model of boot, not from that actual boot. The reason for this is that there were likely many pairs of boots made with the same kind of fur, or even more than one pair from the same animal pelt.
IF they can source the fur at the crime scene to a specific animal and then source the boots themselves to the SAME animal- well then that proves the fur in her hand were from Patsy's boots.
But even that can be argued away by the defense by saying that it isn't unusual for for from a mother's clothing to be found on a child. Doesn't prove she killed her.
Now the fiber evidence would also be found to be "cosistent" with fibers from Patsy's jacket. Could they have come from another jacket exactly like it? Yes- but the likelihood of a killer wearing the EXACT same jacket as one owned by the mother of the child he/she killed is so remote as to be impossible.
BUT- fibers matching the mother's jacket that were also found adhering UNDER the tape on the mouth of a dead child and found wound into the knot of a garrote that had been used to strangle that child can have no other venue for being there except that the person wearing/owning the jacket (the mother) also was present at the time of the crime. And she was STILL wearing it when the body was found.
This comes under the classification "circumstantial evidence".
Patsy throwing herself on her dead daughter as a way to contaminate the body by being able to say that was how her fibers got there is actually pretty flimsy.
The body was covered with an afghan by JR before PR even came in the room. The tape itself had been left in the basement. It never came into the room with PR and her jacket. The knot was in the back of JB's neck. She was placed face UP in the living room (with the knot close to the floor at her back) when PR supposedly saw her daughter with the garrote for the first time.
PR HAD to be in the basement or in close contact with the BODY- not just her daughter, but her daughter AFTER she had died for those fibers to have gotten to those places. PR's fibers, even more than JRs, are linked to the actual death and staging. Even more than any DNA these fibers link an actual person to the two things that are items from the actual crime- the tape and garrote.
With JR's fibers - the ones matching his dark Israeli shirt that he wore that day- found in her panties- the defense can always argue that he helped her in the bathroom and that's how they got there. Of course, that would mean JB wore the ridiculous size 12s to the White's (doubt it).
But there IS no defense for Patsy's fibers on the tape and cord, and when interviewed, PR is asked about this very thing. Her lawyer, LW, does not allow her to answer the question.
