In the Original Script of the Pilot Episode, Virgil Menelli's Character in the Script was named RJ Patel, he was Hiller's Choice to be Red John , after season 1 he was too obvious as the number 1 suspect, or it could be because the actor left the Mentalist to be in 24 , but the original plan was to have the CBI boss as Red John , guess what the plan hasn't changed only the Actor , in season 3 Bruno created a new Position"CBI director" and then Enters Bertram who is basically Menilli 2.0 or lets call him Red John 2.0 , this is my logical deduction of who will be revealed as Red John.
