My theory is that not any of these indivuals is actully red john and that "red john" is a secret government agency used to kill potential threats and dangers using the alias of rj. I believe that all 7 suspects are aware of the red john agency and somehow involved. I belive that Jane has been aware of this fact for sometime now. The reason "red john" was able to predict the 7 suspects is because the agency sent 2 agents to retrieve the info from janes chambers "toothpick scene". This is also why Kirkland killed the guy in the hospital when he said he saw Red john The reason Partridge was killed is because he was going to rat out "red john". The reason Jane has not taken out red john by now is because he does not know how to (who to turn to) as all of the top officials are aware of the real red john. The reaon rj has not killed Jane yet is because the red john agency wants Jane to eventually become there new leader.
p.s its pretty obvious now that how red john stole the memory from Jane now while red john was killing Sophie he retrieved the info from her
"red john" is not as smart as he seems.
