I've always thought someone involved in the case (PF or maybe KK or someone he solicited) can be seen on the video and that's why it hasn't been shown. MOO
Maybe. Total spec on my part but what if someone, who she wouldn't recognize, followed her in safeway to be able to communicate to someone else when she was on her way home. Then the person is waiting, possibly hiding when she arrives back at home. I know if I ever have to hide from someone (when I'm playing with my kids, nothing nefarious), I immediately have to go pee. So i would need someone to give me the heads up to get in position so i wouldn't have to wait long. Again total speculation.
