It's not Gale Bertram, or Bret Stiles, but most likely is a tag team made up of:
Kessie Dunninger
Hollis Dunninger
Mandy Schultz
Gangs recruited by these three

Let's look at why these three, or at least, Kessie and Hollis anyway.
Kessie Dunninger from "Redemption".
Why?
1) She has red-hair, so could well be the 'Red John' - the 'Red' part anyway.
2) She may be tag-teaming to do the Red John, she being the thinker and the 'John' being the doer [although who the John is, well, open to question)
3) There has been this theory going round on a few websites discussing The Mentalist. It makes enough sense in context.

But who could Red John's accomplices be:
1) Her dad Hollis, the 'John' of the partnership; this theory was posted on a showbiz site in the UK. 'John', if you think about it... 'John' being slang for an everyman, an average man.
2) Mandy Schultz (who apparently made a cameo during one of the episodes which had Lorelei in it) - helping Kessie plan the murder? (that theory was posted on a website few months back).
3) A small gang of people that are recruited to carry out these murders recruited by the Red John team.

It would not surprise me if Red John was a non-existent person, and just a pseudonym for a group of people, a 'house name' for a murderer if you like.

Theories about it being the CBI / FBI etc. could be debunked based on this line of reasoning; I'm surprised that the characters of Kessie and Hollis Dunninger and Mandy Schultz haven't been added to the accuse list on the site!

The motive, though, is a little fuzzier, but British fans continue to debate why.

I would be surprised to see what your comments are on this theory; it does make a bit of sense, and is widely popular with British viewers.
I am a UK viewer of the show, just for the record.

I have read so many theories and if they really want to please the loyal fans then wouldn't it be badass if red john was Christopher Walken and he would walk in and say to PJ " your talking to me all wrong do it again and I'll cut your throat with a knife" On a serious note the day before the red john episode I will post a link that is already out there that shows Partridge is Red John but for the sake of the show and the suprise I have kept it a secret for two weeks now.

If you feel comfortable with getting spoiled what will happen in the mentalist and who is Red John, continue.

Those
who sucribe to TV guide get it a week ahead before it's 'officially
out'. The link above is a link to a discussion on IMDB thread
considering interviews that were on the TV guide. There are BIG
spoilers...you have been warned.

Tattoos of three dots on the hand means "death to cops" (mort aux vaches) -- not sure what on the shoulder means -- but it seems a very common prison/criminal tattoo -- unless in the shape of a pyramid, then it has other meanings.  So, I'm inclined to think that RJ is not the one with the tattoo -- it's someone else.

RED JOHN is a WOMAN, A REDHEADED, "PSYCHIC,"  EXPERT HYPNOTIST and MASTER MANIPULATOR of MEN.

I read a couple theories that say lisbon is feeding information to Rj. I don't think this is true. A more likely possibility is that she is part of tyger tyger and not knowing she is feeding information to Rj. It would explain why Rj knew jane's list before he told anyone. I don't know if the list is fake or not. It would explain a lot.


Let me know if you agreement

This is Red John running after someone!!
