So I have a theory on the 7 suspects on Jane's list.  Why does he choose these 7 people?  What's so special about them?  I believe some are on the list because they are suspects, while others are merely accomplices.

Brett Stiles.  Jane thinks he's an accomplice.  He's never shaken hands with Jane, but Brett has always hinted that he knows RJ's identity.  We know there's a connection to visualize.  Jane puts him on the list because he believes Stiles will either willingly or unwillingly help him reveal RJ.

Gale Bertram.  He's an accomplice.  Jane knows he doesn't fit Rosalind's description of under six feet with short straight hair, but the man is in on it.  He's the director of the CBI and basically owns the Red John case.  He's always telling Jane "I wanna be there when you reveal Red John".

Ray Haffner.  He was a suspect, and a damn good one.  But he ain't RJ.  I don't believe he's actually involved.

Reede Smith.  He's an accomplice.  Jane never shakes hands with him, but RJ states in season 4, "...luckily I have a friend in the FBI".  Jane has deduced  that Reede is his FBI accomplice.

Bob Kirkland.  He was a suspect, but Jane discovers he was merely hunting RJ... oh and he's dead now.

Brett Partridge.  He ain't RJ, cuz he's dead, but he's very important!  What does he do for a living? Forensics!  Where do we always see him?  RJ crime scenes.  He's the guy who cleans up after RJ.  He makes sure no evidence can lead to him.  This is why Red John kills him.  Partridge knows vital clues and information that in Jane's hands, could identify RJ.

Sheriff Mcallister.  He's a sheriff in wine country.  Not much to contribute as an accomplice.  Not much jurisdictional prowess.  Therefore he has to be a suspect.  As I mentioned previously, they do not physically shake hands, but Jane and Tom play rock paper scissors, where-in you shake your hand repeatedly before revealing either rock, paper or scissors.  Therefore, they "shook" hands.  He's a hunter and as he tells Patrick, he knows how to "clean and quarter a kill".

Incidentally, what do hunters always do to their prey after they shoot it?  They cut the throat and let it bleed out.  What does RJ do to all his victims?  He cuts their throat and watches the life leave their eyes.  Plus, the knife RJ uses is quite possibly a hunting knife.  Take a look at this scene where he saves Patrick.  First he shoots a victim, then he slits her throat.  Plus the knife certainly looks like a hunting knife for quartering and cleaning a kill.

Not a theory, just something I am fed up with.Please, stop saying that Jack Plotnick said his character died, it's his job. If they showed us in the 6x01 that Partridge died, Plotnick cannot say the opposite. By the way, I think he's RJ. 

Sorry for my English.

Here is my question...do we really know anything?

Yeah, TV Guide kind of spoiled some things. Heller let some things out. But overall, is there really a legit guess? I tell you where I'm coming from

1) One of the constant clues regards Rosalind Harker and her knowing his face, voice, etc. But we are going on the word of a blind woman...is she blind?...that could be part of a conspiracy, a cover up or even Red John. We are all chasing this under 6 ft guy guy with short, straight hair because SHE said so. Why trust her?

2) The handshake. We don't know with certainty if the handshake was shown on TV, from early in the seasons, etc. We do know that Lorelei saw it. But here is my rub with that. Tyger/Tyger is a group who may or may not be under Red John. How do we know who she saw shake hands with PJ was Red John? Maybe that person...like Hafner might..worked for RJ but there have been so many associates, etc of RJ she might have been as out of the loop as anyone.

So overall, I guess we have it narrowed down but I think the answer of who could be anything because none of the clues came to as as fact, only as hints from people we may/may not have reason to trust on the show.
