What if whomever has Breeanna did dump the bike? Someone else then finds it, but doesn't need the training wheels, So, lucky bike finder removes the training wheels and just tosses them, strolling off with the bike and no idea of its significance. Makes about as much sense to me as an abductor taking the girl and the bike and for some unknown reason dumping the training wheels. Just a thought...
If the wheels were instead planted near the road for some reason, whoever thought up the staging wasn't thinking too clearly as there's no logical inference to make about the wheels in context to the alleged abduction, imo. IDK, maybe the third piece of evidence somehow draws out a clear staging attempt...
P.s. If this turns out to be a crime that occurred because someone wanted a bike, I'll scream. Recently read about a 17 year old who strangled his mom to death on Christmas Day because he allegedly didn't want to play Yahtzee with her. Madness...
