well...people thought van pelt and rigsby will be killed by RJ..lol

Why Red John did not kill Lisbon? in Episode 6x02 Ray said that he likes Lisbon very much and he hopes to have a future with her. In my opinion Red John didn't kill Lisbon because he loves her, so does Ray. Furthermore Red John is a Member of Visualize, Ray too. Red John worked on the Allistor Farm, Ray too. Sophie Miller's notes says Red John is a good whistle blower, so does Ray.

Red John case is definitely one of the most intriguing things i've ever seen, love it!

Assessing the 7 suspects, now 6 after Partridge is dead (Partridge was definitely an accomplice), I also believe that Bob Kirkland has his own agenda and wants some kind of vengeance against RJ, but not sure what.. maybe he was the boyfriend of Lorelei's sister who got murdered by RJ and he wants to confirm his suspicions..? Only a wild guess there, but the truth will unfold soon.

As for Bertram, McCallister and Smith, they all have a secret that they want to keep hidden because once it sees the day of light, they're career and lives will be in danger. And I think RJ is the one that threatens their secret, as someone else has posted here, too.

Brett Stiles..I would be disappointed if he turns out to be RJ because it just seems too obvious.. however, he is very much connected with RJ and he definitely knows who RJ is..probably acted as a father/mentor figure for him in the past. 

This leaves Ray Haffner, who has been my number one suspect since the release of the 7 suspects. Not only he fits the description by Sophie Miller, but his past, personality, feelings towards lisbon etc makes him the biggest suspect indeed. Really looking forward to the next few episodes, when more light is being shed on the case. 

P.s. someone mentioned that the phobia RJ has might be related to pigeons..I personally find the pigeons scenes highly interesting, and I am not surprised at all if at the end it turns out that this might be true. 

I think that Ray Haffner is Red John. First, he is portrayed by Re(e)d Diamond. Second, alluding to the Where's Waldo reference, I won't be surprised if you can see him in the background (in the CBI) of most of the episodes. Third, he has the skills of a detective as well as the skills of manipulation which he could have gathered from his time in Visualize.

It looks like Kirkland, Bertram, McAllister, and Smith have formed a brotherhood which is involved in dirty covert operations. They're after Red John just like Jane is. Somehow they see Red John as a potential threat to their operation and they're planning to get rid of him. On the other hand they don't want him to get caught by the good cops, since he might know enough to put them down, I'm guessing Red John has even threatened them already. That's why Kirkland broke into Jane's room to get the list of suspects, and that's how Bertram knew Jane was getting close.

Did you notice Bertram's face when he learned Partridge was dead? He was genuinely surprised and kind of shocked. Maybe Partridge was part of the brotherhood too or somehow connected to it, which is the reason why Red John killed him. The only piece of data that might belie my theory is the fact that Kirkland didn't ask Lennon about Red John's identity, which would suggest he already knew him, then it wouldn't make sense for him to follow Jane's progress on the Red John case unless he is Red John himself or an accomplice, which would totally blot out my theory. I think I've been looking at it the wrong way all along, with the presumption that Kirkland knew what we knew namely Lennon being Red John's accomplice. Jane and Lorelei were the only ones that knew it back then. So what if Kirkland killed a potential Red John witness for an entirely different reason without having the slightest idea what he was actually doing?

The conversation Bertram and Kirkland had plus Homeland's access to the Red John case, and the conversation Smith and Bertram had after Jane left all support my theory. I believe Red John will kill one of the them very soon.

Facts confirmed by Heller as truth and not Red Herrings:

Every piece of info in Season 6 is the truth
Red John is a man
He is on the List of 7
Patridge is dead

So with that knowledge and things we know from the past we can narrow the list down.
It's not Reede Smith as he is not fit as described in Episode 2 of Season 6
It's not Stiles since he is too old HOWEVER he could still be involved (likely)
It's not Bertram since we know Red John has dark hair (not neccesarily black since in a dimly lit room dark is easily mistaken for black) and Bertram is bald.

That leaves Kirkland, McAllister and Heffner. It's PROBABLY not Kirkland as it would be the easiest pick. Also, he had people break into Jane's room AFTER Lorelei was dead. So he could not deduce the list from those files since he saw them AFTER the video with Lorelei was made. Furthermore Red Johns accomplice did not recognize him in the Hospital. So Kirkland is out.

We now have McAllister and Heffner left. Both VERY likely candidates, both match most of the various descriptions given and both would match the build of the peole we have seen to be Red John. Heffner is connected to Visualize and Stiles. A theory would be that Heffner is Red John and Stiles was his Mentor of sorts or functioned as a father figure when he developed his killing habit. This is a very likely scenario. Alos he appeared in a few episodes before and is incredibly charming. Jane did trick him but that could be a ruse.

McAllister is likely because despite just having one episode earlier, it was written by Heller himself and he fits the age (as in the show he is roughly 50) and also has an interesting thing going on. He is the head of the department in Nappa county and interestingly enough the episode with him is set there where also coincidentally two of Red Johns deciples were killing people. He did lose in Rock Paper Scissors against Jane but that means nothing as he could have easily faked that.

So those two are the most likely candidates IF Heller was telling the truth and not lying about the facts stated above. 

Stiles knows who Red John is since he worked on the Visualize farm. So if McAllister is not revealed as a Visualize Member we have our answer. Personally, I believe Haffner is Red John with Stiles as his mentor, maybe even being Red John himself with Haffner as his protegé.

November will tell :)

Hi all,
Like most of you I was also convinced that Brett Patridge is Red John. But now that he is dead as confirmed by Bruno Hellor, I checked all 7 suspects again and finally came up with one name - Ray Haffner. My theory is as follows.

1. We have seen that Red John is technically sound as he has hacked into CBI firewall many times. Also, he is very good with surveillance techniques as seen in Episode 1x23. 
The same goes for Ray Haffner as seen in Episode 4x02 in which Lisbon describes Haffner's strength as surveillance techniques. Also, being a member of Visualize Ray Haffner is probably connected to some of the big guns of the state as well.

2. A key point which I over looked first time was that In Episode 4x02, Ray Haffner holds his tea cup in left hand while talking to Grace Van Pelt. In the very same season's Episode 4x13, we seen that 
Red John also holds tea cup with his left hand. Coincidence???

3. Rosalinh Harker's description of Red John matches exactly like Ray Haffner's. The only difference is the voice which has thrown off most of us. But I think Haffner somehow changes his voice with some devices or gadget, I guess. And this makes complete sense. Would an incredibly careful and clever killer like Red John flaunt his actual voice ???

4. Red John somehow managed to hypnotize Kristina Frye after he captured her. He made her believe that she had died and turned into a spirit.
We know that Ray Haffner was a member of Visualize . I assume that he learned hypnotizing from there.

5. One of the biggest clues about Red John that we found in Episode 6x01 is that he addresses Agent Lisbon as "Teresa". He uses her first name as if he is Lisbon's friend. 
Among all the 7 Red John suspects, Ray Haffner is the only person who calls Agent Lisbon as "Teresa".

6. A big question arises in the climax of Episode 6x01. Why did Red John spare Lisbon's life. Patrick Jane feels that Red John got spooked somehow or there was lack of time. It may be true. 
But another possibility is that Red John has feelings for Lisbon. 
Ray Haffner also expresses his feelings for Lisbon in the very next episode (6x02). He says he likes Lisbon and hopes to have a future with her. 

7. And finally we come to know about a habit of Ray Haffner which makes him a very favorable Red John suspect. Sophie miller's notes says Red John is a good whistle blower. And so is Ray Haffner as he whistles in the hospital after meeting Lisbon.

8. Now the biggest clue of them all. Remember Lorelei reads out the list of suspects at the end of season 5. While she reads out the names, she takes a long pause before saying Raymond Haffner. I assume that Lorelei was surprised that the actual name of Red John is in the list.
