Hey guys, i wont to share my "Big Bang Theory" with you. This is a copied post from the german version of this website. I just used the translator, because i needed to long to translate it by miseld. Also my english ist not that good. I hope you could follow my theory. Have fun...

I will summarize again :
We have 7 suspects in which Bruno Heller has confirmed that one of them is definitely Red John . Patridge and Kirkland have already been deleted. We have to note that Red John has a good appearance, a " fit " body has and has a good network to the CBI . I dare even the thesis that there is no way to Haffner over!

My arguments are as follows:
Stiles,
Bertram , Smith and McAllister not conform to the description of the
therapist , whose recordings ( acrophobia , handsome , middle age) ,
Jane found . We still know that he has an undeniable success with women . For Haffner , however , applies to everything we have heard so far . I have now again looked at the episode "The Red Barn " from Season 5th Here it comes , that is found on a farm from the 80s Visualize the RJ Smiley . Jane finds out that the symbol was placed in the 80s by a young Visualize workers there . Known, Haffner belongs to Stiles ...

Haffner
is addressed in the wake of Lisbon , and he says that he was already in
Visualize but makes the question whether he has worked on the farm. As a result Haffner Lisbon also offers a new job at a private security agency , which he wants to start using Visualize . I assume that Red John Haffner , and the financial resources of Stiles gets provided. Stiles has known, so a wire to Red John .

Furthermore, Red John must indeed have good contacts in the CBI . As a relatively early the lady has been poisoned in the course of the CBI , you smiled before. I hardly think that all volunteers of Red John know each other and was killed by "real" . Haffner can circulate freely there , yes.

We
also know that Haffner has a weakness for Lisbon , which would also
explain that Lisbon has been spared the discovery of the dead Patridge
of Red John .

My guess therefore :
Haffner RJ with Support of style. In the next episode everything is well informed :

________________________________

However, I would hope that none of the suspects is Red John and Jane has noticed over the list that he has the wrong . This calls together and with the explosion , which you can see in the promo preview , death feigning . However, Bruno Heller would have lied for the interviews , which I unfortunately did not go out.

My favorite would be this , in descending order :
Walter Mashburn ( the rich Lover of Lisbon from previous season )
Michael Kirkland ( the -lost brother of Bob )
Jane's brother
