I am not accusing anyone of being Red John but in numerous interviews with Heller after the premier he does state that Red John did KILL Partridge. Whether that means he actually killed him or it means that character will no longer be present in the TV show (because he will only be present as Red John) I am still unsure. He did seem to make it clear that RJ killed him for a reason but we will have to wait and see if that reason is because RJ is Partridge or something else and Partridge is actually dead.
