I've been thinking maybe Sierra was surprised that morning by a knock at the door? She knows the perp, let's her/him in. The perp then takes control, right there in the house.. Sieras scent is left in the driveway not because she walked out of that house, but because she was dragged out. maybe she was already hurt or drugged by this point. this would be why LE finds no shoes or socks? because there never was any? Maybe Sierra was dragged away in her PJ's??
none of the above is fact. I am just trying to think of other ideas...
