I suppose I meant ... dismembered ... when I said "murdered". I think that Jessica walked to the place where she was dismembered, and I don't think it happened in the car.
After that, she was transported. Perhaps some of her remains were taken to the open space, but what if this happened at his father's property (especially if he was away on Oct. 5), and other remains were taken to his mother's crawl space?
It is not surprising that Austin claims that Jessica was hog tied and that she was strangled in the car. It is the best explanation that he can give in order to minimalize his participation in her abduction and murder. As it stands, he appears to claim that he abducted her, hog tied her in the car and then strangled her in the car ... and then what ... he panicked and had to get rid of the body ... so he dismembered her and left her in the open space and his mother's crawl space? That's absurd.
It is the most farfetched story we could ever be fed by a *advertiser censored* addict that abducted, murdered and dismembered a 10 year old child. He is attempting to minimize his responsibility for what he did.
I think the crawl space is a possibility, but that could also be where he keeps his "treasures".
