Dru,
For those that promote the accident theory in all its guises that is an inconvenient question, one that really receives little attention.
As does the common explanation it was just staging well if thats the case why hide it by wiping her down, and redressing her in size-12's and the longjohns, why not leave the sexual assault as it is, so everyone can be in no doubt that this was a lust murder perpetrated by some deranged intruder?
.
For the umpteenth time - the wiping down and redressing was an act of sorrow and it is OFTEN done by parents who kill their children. John Douglas said when a parent leads you to the child, they did it. John led them. Often, often a parent will loving dress the child (in this case, they had approximately 4-5 hours to realize what they had done or realize what Patsy had done and stage the scene) and YOU CAN BE SURE that Patsy took a handful of xanax just to get through. He wiped her down, he dressed her in the wrong size underwear and he swaddled her in a blanket. All the acts of a parent who is franctic and sorry.
