The information below is a collection good of theory's that I have somewhat consolidated. I tried to place as much fact into each of the suspects and their lightly-hood of being RJ as of yet. At the end I have given my personal thoughts on the matter; thoughts not based on fact. Please read and feel free to give me feed back!

Suspicions of being Red John:
~Runs a cult so extremely manipulative like Red John.
~High intellect, has so far avoided jail and held the leadership of
Visualize through his cunning and intellect.
~Knew the location of
Kristana Frye while she was being held by Red John.
Red John verdict:
~While having a strong
connection to Red John is very unlikely to be Red John himself. The voice and
age do not match what we've seen of Red John. Also it is very unlikely that Red
John would help Jane facilitate the escape of Lorelei Martins.

Suspicions of being Red John:
~Quoted William Blake
like Red John.
~Was already on suspected
of being Red John or one of his accomplices back in Strawberries and Cream.
~High level position
which would allow him to develop his contacts and accomplices.
Red John verdict:
~He's a possible
candidate due to his position, but I feel he's been gamed by Jane too many
times for him to be Red John. Also most recently, in Red in Tooth and Claw, I
feel he would not need the help from Jane to do better in Poker if he was Red
John.

The Red Barn
Suspicions of being Red John:
~Has shaken hands with
Jane when they first met.
~High Ranking member of
the CBI.
~Confirmed Visualize
member, but unconfirmed to whether he was at the Barn the same time as Red
John.
Red John verdict:
~We haven't seen enough
of him to really get a feel for him so I place him high on the chances of being
Red John for being a member of Visualize and fitting the age, build,
intelligence criteria.

Reede Smith:
Seen in:
~Season 5 Episode 1 - The
Crimson Ticket
Suspicions of being Red John:
~Part of the FBI
Red John verdict:
~Honestly, I have no idea
why this guy is on the list. We know literally nothing about him. His partner
Gabe Mancini makes a better suspect than this guy does.

Suspicions of being Red John:
~Shook Jane's hand at the
end of If It Bleeds, It Leads.
~Member of Homeland Security which allows him to develop contacts and
accomplices.
~Has a high interest in
the Red John case and Lorelei Martins.
~Kills Jason Lennon who knows the identity of Red John.
~Has agents break into
Jane's room to gather all the information that Jane has on Red John.
Red John verdict:
~Most likely a Red John
accomplice. He met Jane and shook hands with him while Lorelei was in jail so
she had no way of knowing they had met. Also it would be too dangerous for Red
John himself to go kill Jason Lennon personally.

Thomas McAllister:

~Season 1 Episode 2 - Red

Suspicions of being Red John:
~Honestly, I've got

~Probably not Red John, if it's him I will be sorely disappointed.

Red John's Rules
Suspicions of being Red John:
~Completely fascinated by Red John cases.
~Appears at the two
copycat Red John scene saying it was Red John and at the actual Red John scene
says its not him.
~Height, build and voice
are most similar to Red John.
~The Tyger is a poem by William Blake, who also has a painting called A Brace of
Partridge .
~He is creepy and PJ dislikes him from the start. (Accuses him of liking his job too much (Forensics expert))
~His job would allow him to perfectly remove any trace of him.
Red John verdict:
~He is the most likely
candidate for being Red John, but too likely. But he was seen in the very first
episode and important Red John episodes. He may just end up being a red
herring, but he's still at the top of my list of Red John suspects.

Analysis:
In the last episode we are
given the most information about Red John, however there are also
many loose ends that are never accounted for. 







PJ always keeps his study
room locked, however he revels to all of the CBI that he is close to
finding RJ and leaves his study unlocked while he sleeps. He sets
the trap to see if his study is broken into. After finding his study was broken
into PJ is seen burning his evidence, he is also no longer concerned with
Lisbon entering. 







It seems to me that PJ had
his list, but was stuck. So he sets the room up to be discovered. This seems to
be a ploy that may or may not have worked. And it is possible that the list was
a decoy. 

How else would RJ be able to know the list, unless
PJ is RJ and I hate that theory. RJ is clever, but not omniscient.



So I would conclude that while the list could
contain RJ, it is also very possible that the list is incomplete as of now. I
would be willing to bet that RJ grew up with PJ and parted ways as children.
Then when PJ was reintroduced to RJ he was under an alias. That is the only way
for RJ to know so much about PJ, and the reasoning behind the torment that RJ
seems so determined to inflict on PJ. A grudge that could be explained by say,
PJ's Brother or Father.



If we assume that the list is complete and RJ is
one of the seven. Then it would seem obvious that Partridge is Red John.



I seriously doubt we will ever know, and like so many TV
shows before we will always have debates and arguments as to the real killer.
We all hope it doesn't happen, but prepare yourselves friends.



Please let me know your thoughts, and thanks for
reading.

Well, here I am again...I allways keep my promises.;-)

Up to the other suspects:

- Sheriff McAllister: My insiders tip. If he is RJ, he has to be Stile's younger brother, cause the actor is already 57. His shape looks a little like RJ, when he killed Rebecca. And he is from the Countryside (quote: He smells like pine, nails and earth). In addition to that, he acted a little suspicious in the presence of Van Pelt, if you remember. But maybe he is not the the real one. It also could be, that RJ John just lives in McAllister's county and he helps RJ to keep his cover. Maybe RJ blackmailed him. In any case for me McAllister is the one, who abused Van Pelt when she was a child (remember the restaurant scene in pilot). He is a "could be RJ".

- Brett Partridge: Together with Kirkland my second odds-on favorite. Who tf tells, that he is too young? In fact he is 44. Who means, he is crackbrained? He is a forensic expert. But there is more. It's part of the script, that he is head of the forensic department. His rank should be higher than simply "agent" or "special agent". I think, he must have at least a diploma in medical science. And he should have studied criminalistics as well. Yes, It would be a little obvious. But in fact his profile fits absolute everything we ever learned in the last 5 seasons. Height, shape, haircut. He also likes "cold" (Sometimes he surely has to examine bodys in the morgue and "Partridges" typically live in the tundra ;-)). What a great disguise for RJ: Acting like Partridge did, but being a criminal mastermind. That would be a little like Sherlock Holme's nemesis Moriarty, wouldn't it? Conclusion:YES!  

- Ray Haffner: Also a good suspect. Expert for wiretap operations and undercover surveillance, member of Visualize, height, shape and haircut fits the discription as well as his age. And remember the Timothy Carter episode: Bruno Heller stated: "For those with an eye for details, you might have seen RJ in the twinkling of an eye." Noooo. I don't wanna talk about the "Red Sweater Man". But rewatch the moment when the guards surround Patrick after he killed Carter. There's a man with a baseball cap running through the backround (left to right). Imho he seems to look a little like Haffner. And did you notice, that Carter allways answerde with delay? Ranked number 3 in MY list of suspects. 

 - Reede Smith: Reede WHO? All right, he just appeared in episode in season 5. I guess, the only reason why he is on PJ's list is because his name is similar to "Roy Tagliaferro" in other languages. "Reede" is gaelic, I think, for "Red" (nickname "Roy"). And "Smith" - "Tagliaferro" - "cut iron"...mmmmh? And he is too tall and (sorry Drew Powell) a little too corpulent
But he's the "mole inside the FBI", I guess. But Red John? NOPE!!!

That was part 2 of my theories about the 7 suspects. Next time, I will try to explain, what's up with the video, I will subsume the facts and I will try to forecast, what's gonna happen in season 6.

In episode 8, season 2, after Virgil lost it a bit towards the reporters interviewing after four of his men got killed, did we catch our first glimpse of bob Kirkland? You can see someone getting out of a black vehicle, he really looks like BK. suddenly, Virgil decides to retire. Whether or not bk is actually red John is yet to be seen, but we know he's involved heavily.

Someone has possibly already mentioned this but just came to mind ... In
the first season there is an episode in which Patrick and the team have to get
a Red John accomplice out of prison. That very week Gale Bertram decides to go
on a mysterious vacation not before leaving the team without a license to work.
The Red John accomplice manages to get to Mexico and by the time the team reach
him in a motel, he is dead. If only they had had their licenses
they would have been able to work much faster and probably tracked him down.

Now I don´t think Gale could be Red John, Patrick has demonstrated how
superior he isover this character too many times. But an accomplice maybe??
