Bertram looks similar to Sean Barlow. I wonder if Bertram has roots with the Barlow's/carny folk and has a hatred towards the Janes?

LETS BE REALISTIC

Red John murdered a private investigator by HIMSELF. She looks quite fit and looks like she could actually have brought up a good fight, if not win if it was someone weak. 

We have 5 suspects: 
Bret Stiles
Ray Haffner
Thomas Sheriff Mcallister
Reede Smith
Gale Bertram

I can almost guarantee Bret Stiles is not strong enough to single-handedly take down the investigator without trouble. Also, Sophie specifically said that the suspect was middle aged. Does Bret Stiles look middle aged? Very doubtful. 

This leaves us with four. The rest of these seem like they could take her down. 
Ray Haffner
Thomas Sheriff Mcallister
Reede Smith
Gale Bertram

When Reede Smith murdered Kirkland, he put 6 bullets into him, but shot seven. What does this mean? When the report came out, it said that he had 6 bullets into him. Now that usually means to the viewers that, "Oh, Reede Smith might be Red John because he shot 6 times." But he wasn't trying to shoot 6. He shot seven times. 

Also, it seems awfully careless of Smith to have shot a man six times just because he "tried to escape." Why not shoot 1 in the head? He doesn't seem like he has the methodical thought put into things like Red John might. Its unlikely its Smith, and he hasn't been in the show very much at all. 

Three suspects: 
Ray Haffner
Thomas Sheriff McAllister
Gale Bertram

Between these three I can't be completely sure. When Red John visited Sophie, he said that he had a fear of heights, but there is NO REASON for Red John to expose this to Sophie. It is much too risky. However, the whistling part may not have been intentional by Red John. We know that McAllister has a fear of heights, and doesn't like pigeons at all. Interesting? Yes.

Ray Haffner is probably the most likely suspect for all viewers. He likes Lisbon, (there is a theory that Red John likes Lisbon) he was coincidentally gone right when the investigator was murdered. He's fit, charming, and has a Visualize Connection. The private investigator said that she was hired by Visualize. 

This makes Haffner a prime suspect, as almost all arrows point at him. But it seems too obvious. If Haffner was Red John, everybody could see it coming, including most passerby viewers. I feel like there is something larger cooking up. 

And lastly, Gale Bertram. It would be very ironic if it were him, as he is, after all, Jane's boss. We don't know much about Bertram, besides his personality. He evidently doesn't like losing very much. But we don't know if this is a fake personality. 

We don't know who else has a Visualize connection, or else it would be Haffner, but that would be too obvious. So i'll go out on a limb and say that its
Gale Bertram
How fun.

I was re-watching 6.01, and while I personally don't think that Bertram is necessarily RJ, there is definitely something up with him. In the scene where he's telling Lisbon and Jane to take a case far away from Sac PD, he says he is "many things to many people", and is just generally creepy through the whole scene.
Also, when Lisbon is in the house where Partridge died, there is a weird drawing on the wall: http://i.imgur.com/kHrVRS5.jpg.
Thoughts?

I hesitate between Bertram and the Sheriff.
But I think there are also clues in Blake's poem... you may find more:

Tyger! Tyger! burning bright

In the forests of the night,

What immortal hand or eye

Could frame thy fearful symmetry? --> Kirkland Twins?



In what distant deeps or skies

Burnt the fire of thine eyes?

On what wings dare he aspire?

What the hand dare sieze the fire?


And what shoulder, and what art.  --> Tatoo on his left shoulder

Could twist the sinews of thy heart?

And when thy heart began to beat,

What dread hand? & what dread feet?


What the hammer? what the chain?

In what furnace was thy brain?

What the anvil? what dread grasp

Dare its deadly terrors clasp? --> Handshake


When the stars threw down their spears,

And watered heaven with their tears,

Did he smile his work to see?  --> Smiley face after the murders

Did he who made the Lamb make thee?


Tyger! Tyger! burning bright

In the forests of the night,

What immortal hand or eye

Dare frame thy fearful symmetry?  --> Interesting... 'dare' instead of 'could'

My list of suspects:

#1:Raymond Haffner : He had a phobia just like Miller said. He has a lot of friends in the FBI , CBI and Vizualize. He is old enough to be Red John. The woman who entered the CBI told Patrick that Red John was from Vizualize.
#2: Jason Cooper: He appeared in "Red Tattoo" but he wasn´t one of the suspects and HE WASN´T INCLUDED IN THE INVESTIGATION. My point is that Raymond Haffner was there to represent Vizualize but ... what did Cooper do? Did he went there to represnt Haffner?!. He is also a suspect of Vizualize and the wowen told Patrick that red john was from Vizualize.
#3: CBI Ron: Bruno Heller used the expression : "Red John is like a "where is Waldo?" , and the only one who is closer to that expression is CBI Ron.
#4 Gale Bertram : He was in the extended list of suspects of Patrick. He is in the actual list. He was

one of the suspects of Todd Johnson´s death. In chapter 24 Season 3 he was nervous when Timothy entered the shopping , he didn´t stop to look at him. Another point that Timothy´s newspaper was in the same page AS BERTRAM NEWSPAPER!.
---------------------------------------------------------------------------------------------

Connections of Red John:

The only group that appeared was : Reede Smith , Thomas McAllister and Gale Bertram. I think that they are the head of the "Tyger , Tyger" group.

RED JOHN: GALE BERTRAM

I think people are looking to far into it... 
This is just a thought..
It was said that at the end of season 3 by Heller that Jane would face Red John. Not kill him. Just face him. Bertram was the one who faced him in that season. Im not saying that Red John is him. But so far this is the theory that has stuck out the most. Especially Because Robin Tunney said that she was surprised at who Red John was. Which would make perfect sense. As an actress in the show you wouldn't expect it to be the person in charge of the CBI. It also gives him an inside view to everything Jane is doing. And is extremely creepy because Jane sees him almost every day. In the episodes of season 6, Bertram has also 'flown under the radar', there hasn't been an episode on him yet. And he hasn't been shown as someone that Red John could be, besides from being on the list, we have nothing else that could link him.

If i had to choose one on the list it would be Bertram... Although all of them seem to have 'Red John' traits, i think that is to make the fans continue to guess. Which is working, cause the more i read the theories the more ideas i get. 

One thing is for sure but... I am freaken excited to to find out!!!! 

Hmmm, Gale Bertram looks just like my Boss.  My Boss is evil, therefore, Bertram must be Red John!
