This could be a big waste of time and energy.
It can be established that Rodia was stopped, and that that license plate was called in. But since we can't tell who was saying what, it CAN'T be established--at least just from the scanner audio--that Rodia is connected to the license plate. See?
Rodia could just be some local lowlife who happened to be stopped around the time that car was, separately, being called in, and the overlap in two different conversations creates a certain, false, impression.
To really establish this connection someone would have to check the plates through the DMV files. Until there is some believable record produced connecting Rodia to the car, it might be pointless to look any further into Rodia.
