That would make me so happy if his carefully laid out plan didn't include researching how deep the pond was.I guess it's possible FD didn't sit down and take time to figure out how deep each body of water was or to Google them all for that information. I'm thinking he was probably nervous and wanting to get rid of the body as fast as he could. JMO
I agree why alter your own plates and then drop them in a storm drain on the same day you are dropping off bags of JD's bloody clothing? He used them. If he didn't use them, he didn't need to alter and dump them.I have to assume he used the fake plates on a car. I highly doubt the plates were altered just for funs sake, or to alter and then chicken out and just dump them. Hmm.
