I DON'T THINK it's PARTRIDGE.  I think he's dead.  But this website won't let me pick the one I really accuse.  
Anyway, could Jane's FAKE list of 7 suspects hold symbolism for the 7 deadly sins?  I think that points to these characters all having a weakness that will lead to their undoing, and the proving that they're not RJ. 

 
1.  Sheriff McAllister:  SLOTH.  He's a REAL DONUT SHOP COP.  About 20 steps behind everyone, including himself.

2.  Ray Haffner:  GREED.  Money talks but RH is seriously motivated by money as his main interest and goal.

3.  Gale Bertram:  GLUTTONY.  At first, I thought him GREED -- because of GB's poker habit but I realize he has more the desire to win than to just have money.  Another definition is "the ability to withstand," as in glutton for punishment, which GB certainly is, and also an excessive "love of power," or at least for GB, a love of looking good.

4.  Reede Smith:  I thought Gluttony because of his obvious physical appearance but his true point of his nature is: WRATH.  The guy has serious anger management issues.

5.  Brett Partridge: LUST: or blood lust [ghoul!!]

6.  Bob Kirkland: ENVY: he truly seems in direct competition with Jane and the CBI, but why?  We don't know yet.

7.  Brett Stiles: PRIDE:  the biggest ego of all -- I think he could have a connection to RJ, but isn't actually him.  [Perhaps a father or father figure maybe]

Hey guys... I have been thinking about who red john is for awhile now and i must say that i cannot tell for sure whi rj is but i came up with a theory and a possibility... First lets remove some suspects

Bret partrige - i think the dead wasnt fake, although he would make a great red john...
Sherif- he is just not the guy, he isnt the right age, height and the fact that he hasnt been shownin many episodes...
Reede smith - despite the fact that his name is an analog of the red is me Jane met him after the conversation about the handshake so that made me think, why would jane even put him on the list.. that makes me think that the list could be fake...
Gale bertram - i think he cant be rj, he acts wird when he says in 6s1e i hear you are getting closer, maby he is connected to him, but he isnt rj.

Now lets get to sirious facts and my theory..

Bob kirkland - i think that he is rj's brother.. i think that he is rj's right hand he asks the guy if he recodnises him simply because bob and the guy have seen before but bob have made a little transformation idk like he let his hair grew or smtning like that, he also thinks that jane doesnt know about stealing he information and i think jane planted the list. Ok lets move on

Brett styles - i think he is rj's father he knows very much about him, but he is on neither side, he just wants a good show either jane cathes red john or not.

So we are down to ray haffner - if the list is right i think he is the only one who could be red john. He is right age and right height.. in my oppinion people who are on the list will start dyingone by one and when cbi will think they finaly have red john even the last suspec on the list will die.. i think jane has another list, that has 1 more name on it and that one is red john, and that name exists just in janes head, he didnt tell it to noone because he knows that they would do something about that person if he told him.

Soo sure there are some questions abiut the happy memory and why would rj even kill his family...
