Based on the promo for next week's episode, I think RJ's next victim will be Sheriff Thomas McCallister.  It looks like his body on the ground.  If PJ made up a fake list of 7 suspects, Kirkland may be torturing PJ to get the real list of suspects.

its blaitanly thomas mcallister, i can list a series of reasons. my reasons are based on the episode 'wedding in red' First off his phobia of heights which he gives away to lisbon and Jane.   second his fear of pigeons, thirdly the way his voice is very much like red johns on the phone, he seems to have a sudden change in voice when on the phone to jane and then even more bizzarely he creeps up behind jane immdiaitely after jane hangs up the phone, and shows abit of nervousness around jane and comes up with the excuse of hunting when jane asks why hes right behind him. another fact is that he saves janes life makes me question thomas mcallister even more as he has previously save janes life in series 3 where red john picks jane up by the chair and says to jane 'if its one thing i wont tolerate its cheap mutations of my work' and shoots the people trying to kill jane.  hes also very good at examining the body in the episode where him and jane are discussing the clues based on the body. he's very quiet at following jane around in the church and at the pond where jane is on the phone to mcallister. he seems very psycholoigcally clever the way in which he examines the body with jane aswell.

Lets see how ppl are posting their theories i this site..

After S06e01 --- most of them says partridge is not dead,he might be RJ.

After S06e02 --- Everybody claims Haffner is RJ.

After S06e03 --- Everybody says Tom is RJ.

common we are being played by the writers !!!

I think Bob Kirkland is not RJ because of that:

[IMG]http://i42.tinypic.com/2mq6jd0.png[/IMG]  can anyone tell me who this is?

1) THE LIST IS FAKE !!!
REASON :-Jane knew someone was spying on him during he was creating a list on RJ. So he misled by giving fake clues.
2) The video made by RJ was not before Jane arrived at the list.
REASON:- Let me give you an analogy on how magicians perform their tricks , They say to us all the props used are genuine and infact that is to mislead us.Now how can RJ make us believe the list was made 2 months before ?? exactly put a dead person revealing the names...now no one doubts when was the list made ... My point is the list was made after Jane arrived at the list may be using a double or something that will be revealed in the future.
3) Now in s06e04 BOB KIRKLAND knows he has been fed with wrong information , since the list arrived at by red john is fake. what jane all this time.
4)so RJ ie BOB made a video and sent it to Jane but gets to know somehow that he has been tricked by Jane and wants the real list since he feels its an embarrassment to SHARE CREDIT FOR HIS ART!! 
5)So BOB wants reveal he is RJ because he can't live with someone who is unworthy is even being considered to be capable of doing what RJ does.
6)Hence BOB wants to kill all the people on the actual list.
7)The conclusion is Jane makes RJ to revel himself instead of him finding who RJ is since he knows RJ is way better than him.
