One other thought I've had regarding the detective picture.....it appears there is a semi-circular white line surrounding the detective and the footprints. If a vehicle was used in the abduction, could it be possible that the perp dragged Jacob from the abduction site in the grass, then an accomplice swung the vehicle in a turn to accomodate the perp forcing Jacob into the car. This would mean that footprints would only appear in this one location along the entire 40 yards. As Trackergd stated, the perps and Jacob's footprints are intermingled in what appears to be a struggle.
