@kittythehare . I get hung up on the animal angle as a possibility when I think about the tracking dogs and searchers that combed the area. It would seem that a wild animal would have left behind evidence of torn clothing at some point. In the immediate perimeter around the house, maybe
@Trackergd can give insight if an animal would have left a trail such as: flattened grass, broken twigs, or a clear disturbance across a dirt patch or the driveway as it would seem an animal would drag rather than lift and carry.
Just my thoughts as I attempt to explore the possibility presented.
