I've been through various scenarios with regard to the staining on the pants and I've formed the conclusion that I think it is urine and the ammonia component that over the long period had the same effect as bleach. I don't think we can compare clothing or soft furnishings that have been washed soon after their exposure to urine. Someone posted an article yesterday that showed pet urine on carpets has this bleaching effect if it is left uncleaned for a long period.
I think the photo of the pants shows the following:
The urination happened while Summer was in a seated position.
I've ruled out the following positions:
- standing upright, because the urine wouldn't spread upwards and rearwards through the fabric to her buttocks area. Even if she was standing up and then made to sit down the majority of the urine would have gone wherever it would go by gravity and not be sufficient to make the buttocks area upwards behind her so wet.
- lying on her back or front, because the urine wouldn't run down the entire leg, or even drench the whole length of the leg uniformly, it would pool underneath her on the surface she's lying on.
- lying on her side, because there's again no reason for the urine to run down the leg, and again uniformly, it would soak her whole hip area to the ground, and even if it did soak her whole lower leg with her legs pressed against each other the urine would leach from the drenched lower leg fabric into the upper leg fabric at least slightly.
I think she was seated and then the pants have been pulled off her with the right leg pulled inside the seat area and the left leg of the pants coming off without being pulled inside. So the right leg stayed bunched up inside the pants and the urine soaked into the inside leg fabric that remained touching the wet crotch area of the pants.
If I apply this to the bleach theory I can't think how bleach would be applied in a seated position while she was wearing them. Even if she was made to sit in a pool of bleach I don't think that would spread upwards through the back and the front crotch area of the pants so extensively. And I also don't see what would be the purpose because if the purpose of the bleach is to destroy his DNA because she has been raped her pants were already off.
If I were to theorize further I would say she could have been killed in a seated position (and her bladder expelled its contents) in the house but then there would be a wet chair in the house and she would fall off the chair so I don't think she would have been seated long enough for her bladder to expel that much urine before she went to the floor in a different position. Unless she was bound to the chair, with say painters tape. That is a serious possibility IMO.
Another theory would be that she was kept alive somewhere and was seated (perhaps on the ground) and she either urinated through fear just prior to her death, maybe witnessing the other murders, or because she was just held so many hours that she had no choice but to let her bladder empty.
MOO
