Question to AK and all others.
If sexual assault with an object took place at the death, concurrently, immediately prior but not earlier. the questions needed to be answered:
-what position JB was at the moment of sexual assault, was it the same as at the garroting, or they were turning her as a doll back and forth?
-why her white pants was urine stained but not blood stained more profusely when at the death it all came out of . Her pants were on her and it would be more than several droplets of blood.
-where the rest of the blood on the carpet if sexual assault were at, concurrent and immediately prior to garroting but on the alive girl. It should be much more blood, if her heart was pumping
-was the particles of the cloth found on the carpet if some thick cloth was added for protection against blood
-when the wiping took place, if she had already her pants back when dying face down.
I do not see the sexual assault happened on the alive girl at, concurrent, immediately prior, bc it`s inconsistent with the factual evidence of her pants and carpet with urine stain but without blood , except several drops inside the underwear
If assault took place right after the death, after the not bloody urine came out on the carpet, after turning her back face up, assaulting the body with blood stopped running in her tissues, then it looks consistent to the crime scene evidence. Then it was enough to have just fabric glove(tan color perhaps, or dark ?) to collect small amount blood and wipe the body. Consistent to me, my opinion only.
