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.
