Hi guys, I'm the author of this theory:
http://www.whoisredjohn.com/See-a-theory-Red-John/3981
I was happy to see that my theory was so popular it actually got to be #1 of the month, with 97 positive.

Now, today I wanted to write a brief about the other suspects in the list, instead of telling you why it has
to be brett partridge, i will analyze the other suspects instead, are you still reading this? great!

Bob Kirkland
Well guys, Bob Kirkland can NOT be red john.
People say "well any of them can be rj because they are in the list" - don't forget that we know
details PJ doesn't know (yet).
+ Connections in the higher league.
+ Correct Age, Hair style, Height (below 6").
- Jason Lennon told Bob Kirkland that he doesn't recognize him, tho he knows and works for RJ.
- Bob Kirkland killed Jason Lennon which was the only way to reach to RJ.
- When Bob Kirkland killed Jason Lennon he didn't leave the RJ classic smiley face.

Bret Stilles
A very manipluative guy, is the head of 'visuallize', and killed before, has a lot of money.
+ Connections and money.
+ Mentalist, just like PJ (or maybe even better, no one knows).
+ Correct Height (below 6").
+ Head of visuallize.
- Needed the help of PJ in order to catch the guy who tried to destroy him.
- Wrong Age, Hair Style.
- Doesn't hate PJ (for as much as we know, he even helped him).

Brett Partridge
My prime suspect, i believe he's the guy based on my RJ theory.
He proves to be very evil, cold and a potential serial killer, and he matches RJ's profile by Rosalind
Harker.
+ Correct Height (below 6"), Age (47 according to Wikipedia), Voice (sounds very similar to RJ).
+ Resent to PJ, laugh and tease his "mentalist" power, and tell him he's doing the real job here.
+ Talks and behaves as a potential serial killer, calling dead people "human candles".
+ Possible connections from his job, with the help of other friends like Bob Kirkland/Bret Stilles.
+ Talks spanish, and have people talking spanish, just like RJ.
+ The "tyger tyger" RJ said, by William Blake, also has the poem which is called "Bless of Partridge".
+ Read William Blake's poetry, just like RJ.
+ PJ said he gets wierd feelings from Brett Partridge, saying Brett Partridge is a 'Ghoul'.
- Unknown money status, doesn't seem to work in a very rewarding (money) job.
- Always thinks that RJ made the fake RJ killings.

Gale Bertram
Sounds like a classic RJ, but he doesn't fit in the profile.
+ Suspicious behavior, near to Bob Kirkland and saying to him "She knows more than she tell..".
+ Money (unsure if he has a lot of it) and Connections.
+ read William Blake's poetry, just like RJ.
+ Appriciates PJ, always cautios about him like asking Lisbon questions about PJ.
+ PJ said he gets wierd feelings from Gale Bertram, that something with him is wrong.
- Got Tricked by PJ.
- Possibly wrong Age, Height (above 6").

Reede Smith
Just a suspicious character, a great conspiracy suspect guy.
