Red John used to be a member of the Visualize. We know this because of the case where they found 3 dead bodies on the basement of an old Visualize farm. On that episode Lisbon also found out Ray Haffner was on that farm too, and he used to be a Visualize member. I cannot recall Lisbon telling this to Jane. Ray Haffner's visit to Lisbon and telling her the reason he didn't kill her, "I like you Lisbon" makes sense, because we were all wondering why didn't  Red John kill her? I don't think Bob Kirkland, Gale Bertram, Thomas McAllister know who Red John is but they obey him for sure. I think anyways it's kind of weird that Ray Haffner visited her, maybe he didn't kill her because he thinks she knows about the visualize farm thing and didn't tell Jane. 

I also think it's kind of awkward that there is Grace called Red by Rigsby in the CBI

Can anyone answer for me who Grace is getting married to in this clip sure doesn't look like Rigsby to me ??

I'm still trying to figure out how RJ compiled the list of 7 suspects. To me this is the biggest curiosity yet to be explained. In my opinion it can't be via Kirkland's theft of Jane's board and material for one simple reason. We see Kirkland is still studying the board AFTER the list has been compliled.

If Kirkland is RJ or an RJ confederate then he wouldn't be studying Jane's board after the list had been made so he appears to be actively hunting RJ for his own purposes.

Truthfully flaws can be found for each of the suspects but from a simple description perspective Smith, McAllister and Stiles just don't fit the criteria. Smith is fat & Stiles & McAllister are old. Partridge is dead so that leaves Haffner and Bertram both of which have been pointed at pretty strongly as being RJ. I'm guessing Haffner but in reality he and Bertram are too tall based on Rosalind's description.

All I know is the first two episodes of the season have grabbed me again. I can't wait to see how this all plays out!

I think Ray Haffner could be RJ. He wouldn't harm Lisbon because he really likes her, and he calls her Teresa, just like RJ did in his phonecall to PJ the day BP was murdered. Who else calls Lisbon Teresa? I'm planning on reviewing the whole series again for this, unless someone knows this already? (He is an excellent whisteler and is of the right age and bodytype etc etc)
Still have some untied knots about Ron's role, and the reason of Wayne and Graces "disappearence" from the series....

Wow guys , you really make me laugh ! Can you please stop posting stupid theories about Partridge being Red John ? He is so dead , it was confirmed by Heller and by Plotnick himself ! Why would they lie ? You guys are too obsessed with the ideea of Partridge being Red John so you can't get it out of your mind . As for Jane being Red John , those theories are the most stupid i have ever read on this site . It makes nonsense and this will also make this show a totally crap one ! So please , use your head and just stop posting useless theories .
My money goes on Haffner or maybe Stiles (but he seems a little bit too old .. )
Cheers!

Not really much of a theory, but I've been thinking.

Even though I hope this isn't the case, it might be possible that red john is a psychic.

'He is mar' could be 'He is magic' as well. It could be an unfinished G. If not, it probably is 'he is many', because I don't see how the handwriting would indicate a proper R or a D, in 'he is married' or 'he is mad'.

Just chose Haffner because I like him for being red john, although I think the evidence we have is way too ambiguous for me to be sure it's him or not.

RJ is not Jane! How can he talk to himself on the phone and save his own life when he is tied on a chair? 

Some people say that Mcallister should be RJ because he's only seen in one episode of the first season. No! All suspects are in the list because all other ( male )  people who shook hands with Jane were out ( age, place, etc. does not match with one or more RJ events ).

I think the key is Partridge's death.. Why did RJ kill him?  Why did Partridge say "Tyger, tyger " ? Why did RJ want Lisbon in that scene?
