This is not so much of a theory but mealy a few of my observations. From what we understand Red John leaves the "smiley" at ever murder he commits, correct? Was I the only one who didn't see one at the latest scene. As Patrick once said "Red John is a showman." This leads me to believe it wasn't Red John? But maybe I've made an error(please correct me if I have.) 

My second observation is that Van Pelt and Rigsby's lives seem to be going along rather easy of late. Almost too good to be true? I can only think that there is action to come for these two; and with the two actors leaving the show I wouldn't be surprised if Red John became involved. 

Finally as I look to the new episode's promo. All I can think is it's too easy and according to the episode title's too soon. However I can only feel like Patrick has a plan. And this plan will be his best ever, I just hope it isn't a boring ending. We want excitement and drama and I feel like some of these new episode have been more about dropping lots of false clues. 

I genially have no idea who Red John is, I was sure it was Partridge before the list was revealed(due to the theories on this website.) But he's dead and anyone who argues that he isn't is delirious. It seems to easy to be Haffner or the sheriff as they have dropped too many clues. And as far as the physical description goes, we shouldn't trust it. Red John brainwashes everyone along side him to do what he says, so surely he could of planted false information?

Hello Mentalist fans,

I would like to tell you, Bruno might be "deceiving" us again with the identity of Red John. He told us RJ was in the series since the very beginning, which have gave us a big hint on who Red John is, here are some:

1)- Thomas McAllister- Sheriff who appeared during the first 5 episodes.
2)-Linus Wagner- First episode killer caught by Patrick.
3)-Ron (CBI Ron)- Appeared in the background in various episodes.
4)-Virgil Minelli- CBI boss during the first 2-3 seasons, appeared in the first few episodes.
5)-Brett Partridge- Head of CBI forensics, appears in any of the RJ killings, or in that case, copy cats.

These people are the most likely suspects, since Bruno stated Red John was in the series since the very beginning. Noticed that the victims in S1E2 Or E3 are Redheads? Also, Rosalind Harker is a Redhead.. Notice something odd? Perhaps the reason the insane couple who brought redheads into the Motel is for RJ to rape them, since Patrick told them to stop what they were doing, and they responded, odd? Maybe. This points out that one of these men are Red John, perhaps I am wrong, but most likely would be one of these men, since Robin Tunney stated that she was very surprised when she knew Red John's identity, and the list made by Patrick is another trick by Heller, like the Finale in Season 3, when we thought the person Patrick shot is Red John. I am just stating my opinion, correct me if I am wrong in the comments section. 

Thank you, 
Wilson 

Even CBS has said that there is only 5 suspects left. STOP talking about Partridge! He is done! Stick a fork in him! Curtains! Good night, Lucille! The End, That's a wrap! Brett Partridge is no longer even an actor for the show, The Mentalist anymore!
