I think Red John is many people
Point Man - The voice and face of Red John ( Brett Partridge)
Money - Walter Mashburn
Connections - Bret Stiles
He has to have someone in the CBI Why wouldn't he
Another Note her Tommy Volker or whatever i thoug he would be connection to Red John somehow because Tommy is a show off. He knows you know he did it but he knows you can;t proof it he has money and people high up in the goverment. He is just like red john but you dont know who red john is so its gonna be that much harder to find out who he is.
