This is not a theory and im not accusing anyone here.
This is for the admin(s) of the site.
There are certain glitches in the site. for eg Bob Kirkland has been added very recently to the list of suspects. But there have been a lot of theories in which he was accused before he was officialy put on the list here. So these theories are now null and void as they have not been counted as theories against him. Work on this please. This is probably also true for other suspects.

I have watched this show in it's entirety over and over and over again. Fine, ok, I'm obsessed. Who the heck is Red John? And do the producers and writers know that they are driving us nuts? Probably. Here is my analysis of Red John.

1. For everyone guessing it's Patrick Jane, are you kidding? Give me a break - that would make the worst show ever. This show is about Patrick Jane's struggle for redemption. The irony that even though he would never kill his family, he feels his actions have killed them. His endless pursuit to do good and redeem himself from his past sins. Can you imagine getting to the end of the show and finding that Patrick Jane is Red John? Most depressing show ever. I mean, really.

2. "He is mar" - I believe was an unfinished "He is many". This is before we know that Red John has disciples, literally, everywhere. Foreshadowing for the neverending list of disciples and followers.

3. Throughout the show we have these Visualize cult members who pop in and out. I believe that this is also foreshadowing for the type of person Red John is. In Episode 5.13 "Red Barn" We learn some pretty creepy things about Visualize's first years and the fact that there were some unfortunate members. I believe that this means that Red John is a Visualize member gone rogue. He has the believes of Visualize, the powers of manipulation and hypnotization, and yet he has his own agenda. 

4. I don't think it is Bret Stiles. I mean, hey.. he could be right? But I think it's too easy. Bret's been helping Patrick, with the escape of Lorelai, with Kristina Frye's address, I think that he has channels to get this information because of the Visualize connections. In Episode 2.23 Red Sky in the Morning, Bret Stiles says "I know more than you or Red John could ever know". I believe he said this because he was once Red John's "master" in Visualize, before he went rogue. 

5. Always remember the physical description that we get from Rosaline Harker when thinking about who Red John is. He is just under six feet, has short straight hair, is neither soft, nor overly muscular, and loved to hear her play the piano, particularly Bach. She says that Red John has strong, rough hands. This rules out suspects like Gale Bertram, JJ LaRoche, any WOMEN (good grief guys.. Van Pelt? come on....).

6. I think that having Red John be the forensics investigator would bring the show full circle. He's been around the entire time, and he's always present at every "Red John impersonator" crime scene. He fits the physical description, and Jane abhors him, more than other characters on the show. Plus he's super creepy. Who doesn't want a creepy character for this role?

That's my long winded theory. And good gosh darnit I want to know what happened to Kristina Frye. I also want to know who Timothy Carter was and what the heck he had to do with anything. 

Oh, and I also think Van Pelt is either hypnotized or a secret member of visualize. She will play some kind of role in all of this but against her better judgement. But that's just a guess ;)

I am not really sure...

What if Lorelei has never met the real Red John? What if she has just met another one of his minions?  We really don't know for sure.

Why are people adding people in as suspects that don't matter? i.e. Grace's dad (what does he have to do with ANYTHING), Lisbon's youngest brother...

Are people so desperate for a solution that they will include characters that have NEVER been on the show? Lisbon's youngest brother has never even been mentioned by name...come on people...really?

I love the idea of speculation but stick to stuff that makes a modicum of sense...

(This is NOT a theory of RJ)

In S05E05 Red Dawn, when Hannigan moved to another unit, there was a quick scene with the profile of GVP. I tried getting the text out of her bio, so here's what I have (some words are unknown, referred to as ???? because the text was so small to read):

"Van Pelt is from a small farming town in Iowa. She tends to be overly sensitive at times, but is very intelligent. Van Pelt works with Det. Chillings most of the time, but occasionally works with the FBI or SFPD. She is the gold standard of the team, having started her job in the year 2000. Grace's cousin is supposedly a psychic, causing her to sometimes argue about matters of faith. In the case of 788728-009, the suspect made a remark about Van Pelt's character, stating "...you're deeply depressed and emotionally shut down...because of a trauma in your past that you've never spoken with anyone...ever...even yourself..." which Van Pelt's facial expression seems to confirm. In the case 459959-001 she is ???? for ???? due to a killer who is killing red haired people, leading her to being in an uncomfortable situation"

- The psychic was her cousin Yolanda
- The trauma referred to is probably Van Pelt's sister which she lied about to Rigsby (S02E10 Throwing Fire)
- The serial killer part is very interesting
