How do the farmers in the area irrigate their corn? If the ground is moist you would see obvious signs if she had been taken deeper into the corn. I do believe this was an abduction with a car with one person. If two people and had a truck or van, they would not simply toss the bike in three or four rows, they would throw the bike in the back and take the sunglasses, only takes a few seconds to grab that stuff. I think this is a lone person, working to control her, hence leaving behind glasses and just slightly tossing the bike from where they stood or rolling into the corn from where they stood. This is all just my opinion. I wonder if their are any tire tracks where a car pulled over near to where her bike was found. Silly as it sounds, I can tell when my mailman has come, i can tell the fresh tracks even in dry/dustlike dirt to the tracks made the day before...
