Great point! I continue to wonder just exactly what LE knows that leads them to believe that bike was dumped shortly after she was taken/abducted? What could it possibly be for them to determine that?
It would've been impossible for them to keep from the media if the bike were found earlier than they admit, wouldn't it? If it were found earlier and the police were maybe watching it to see if the perp would come back? That's my only theory.
