Never mind; a little bit of reading on my part answered the question.
Just as it is strange that a plastered DW entered the home so stealthily and nabbed the child, it is strange, on the other hand, that a plastered DW suddenly went for a long road trip that night. I have gone on sudden, solo road trips before, but I was never plastered.
Another problem for DW is the blood on his jacket. Hairs in his motorhome might be explained away by the child entering it unbeknownst, but how the heck did he get her blood on his jacket? It is fishy that he was thoroughly cleaning everything at that time, as well.
But the maggots are still a problem for th prosecution.
I just think the whole picture is not being painted, here. If DW was the perp, and I can see some of the reasons they suspected him in the first place, it seems to me, queasily, that other people were somehow involved.
Did the cops know whether or not the porn DW had could have been MADE by him?
I had the impression that the nastiest porn item was a Japanese cartoon (anime?) depicting the rape of a young girl. I could see where he might have kept that just because of its unusualness, its bizarre reflection of a foreign culture's underside.
