Interesting, but if this is true, wouldn't it show quite a lot of meticulous thinking ahead and planning on CW's part? For someone who made so many blundering mistakes (leaving their bedsheet behind at the burial site, doors from home all left locked from inside, Shanann's purse, keys, phone and meds in the house, being clueless to questions about who she was on a playdate with, etc...) I can't see him thinking ahead enough to strategize, "just in case the police find the bodies, I'll transfer DNA from Shanann's hands to their throats to frame her". I don't think he thought the bodies of the girls would ever be found in such a remote location. All just MOO, but it feels contradictory to me.
