I just remembered one episode someone said something like "the man who ran Visualize before Bret did i don't know but something like that someone look it up or something maybe Red John is the man who ran it before Bret did it would make sense 

Red John is someone Patrick Jane has met.

Someone who is or was a part of Visualize as long ago as the 80's.

Someone known to Bret Styles.

Someone that viewers are not likely to suspect, but who viewers will likely recognize.

Answer: Jason Cooper

Allright, with only a few more episodes left.  

  -Next week we have an old lady with Brett Patridge back. He will be eliminated as RJ..and that is probably all that will happen..I don't think this and last episode has much to do with the RJ story arc.

-But on March 10..Lorelei comes back...hmmm...We knew that she would. As well as Robert Kirkland, But what is interesting is Christopher Cousins is in this episode...let me be the first to say that good old Ted beneke from Breaking Bad is the killer in this episode...and maybe even Red John...heh..maybe..


Nah..I don't know, but hey that episode seems loaded..then in a few weeks we have an episode titled "Behind The Red Curtain"...my guess is that is the episode that Red John will be revealed..what do you think?

Basically i don't quite know who RJ is but i have some really great suspects:

-Ellis Mars:he doesnt really fit the profile and Visualize story, but he ated as a fake physchic,he gave Jane the Tyger burning bright card, he even tried to hynpotise patrick, and what i believe is the most important, he was able to be in direct contact with Todd Johnson..just imagine that and rewatch the whole scene where todd is reveiled to be the killer..if we count the visualize story, id guess he could be bret stiles' brother?

-Brett Patridge:well he couldve been bret stiles son but that would be alittle bit weird..he fits exactly in the profile and that is one of the most important things of him being a suspect, and what is really weird is the mirror scene in red sky in the morning? what in my opinion saves him from being a suspect is the fact he works in the CBI and he wouldnt need a mole like Craig O'laughlin, but it's also really interesting that he will reappear next sunday..last time he appeared was also the last time red john appeared!

Bret Stiles:He isn't red john, way too obvious, but i believe that he was some kind of a maker of red john, he is either his father or teacher...he didnt want to reveal the video tapes but he still knew the information about kristina frye,and all the newer episodes are pointing all the red john evidence against Visualize...but in 2 episodes Lorelei will reappear so it will get interesting!

Gale Bertram:he didn't really fit to me as a suspect but the Tyger Tyger poem reciting was way too weird, right at the moment of Hightower investigation, and the call he was making in the season 3 finale..i believe he is the only one who knew where Jane and him were meeting besides Cho and Rigsby...and he also cares about media way too much and he shook hands with Jane!

Walter Mashburn:in my opinion:HELL NO! even tho he has way too much money and is bored, there isn't any more evidence against him...its true he almost always wears red and he seduced Lisbon, but thats it...he doesn't appear as a killer, not even a bitt like a serial type!

Robert Kirkland:He appeared in two episodes, he seems to know Lorelei really good but it doesnt really make sence how Lorelei knew he and Jane shook hands,i believe he will be the one who will help Jane in the end, even tho it is really weird that in every of the Lorelei episodes he appears too!

SOME STRONG FACTS?:
-Ruskin means Cut Iron, that is probably why he choose to be Tagliaferro,
-it might have happened that Jane shook hands with red john before he killed his family,
-Bruno Heller ALWAYS directs first episode of the season, last episode of the season and one in the middle of the season..and all of them seem to be about red john, only one which red john isnt mentioned is Red Moon and Code Red(thats why Ellis and Harken are so strong suspects)
-Lorelei's sister case will be really important in finding Red John, but i dont think that she will accually lead Jane to him
-most of the main suspects WILL reappear till the end of the show,Patrick will slowly kick them out of the list while meeting them, first one is Brett Patridge,thats why i think that brett isnt red john.

My strongest choice...Ellis Mars

red john is Bob Kirkland season 5 episode 7

Although Ellis Mars seems like a good candidate clue wise, I don't think it's him.  He just seems too neurotic.  His behavior is beneath RJ.

I think Red John is Ellis Mars...

In episode 1X11 the man Red John kills wrote on the wall "he is ma.."
In episode 3X09 appears ellis mars. If we translate into Spanish the first two letters "El" means "he" : El l is Mars
