(BBM) If she were abducted from Redding proper--dense population of roughly 90,000--then perhaps a security system would have picked something up. But she was abducted from Mountain Gate which, like Yolo, is small and rural. Also, Lake16 commented on a previous thread that there's other routes out of the Papini neighborhood that may have been taken to avoid cameras. IIRC, photos also showed that the neighborhood had homes on acreage spaced pretty far apart and back off the road. Really, it's not all that surprising nothing has been found (yet) on camera IMO. Perhaps this was intentional.
