I think everything points to him, or is that just everyone wants us to think? Jane is smart; he would
have figured it out, and I bet he analyzes specific things in everyone
he meets to compare them to Red John, given his past. We can't know for
sure if Jane suspects him or not. Onto the physical aspect, Roselind
Harker did describe Red John as Bret looks. Average height, short,
straight hair, neither strong nor weak, just soft-ish. The calloused
hands would make perfect sense for Bret, given his job. He can be Red
John, or an accomplice. Also, he's perfect for the descriptions as an
accomplice; O' Laughlin was FBI, he couldn't really have gotten deep
into the CBI. Bret could. Big possibility... :)

i have every reasen to say he is red john because red john only appeared a couple times in the show and he appeared  on the first pisode of the mentalist another reasen is that he matched the voice of the man that claims he is red john and rescued jane plus it could be bret stiles  he has a lot of power and money so he could be good for the job

I think it is him because he was in the very first episode at a, "red John" crime scene. He was far too knowledgeable and eager about the crime scene. Also his voice is the same as the red john who saved Jane's life. It definitely makes sense.

Red John is Brett Partridge because if you listen to his voice in the 1st episode and in the last episode of season 2, the voices match 100%. Also he shows up at crime scenes with the smiley face on the wall but it wasn't a Red John murder

RED JOHN IS Brett Partridge with a program because I managed to get a picture! Looks like him .... and then I compared the two voices, and are the same! he is, I'm sure ... he's a CBI official ...

Hi everybody,

Back in 2010, I started a web blog about Red John's ID which I unfortunately took it down due to time restrain. At that time, I was accusing Bret Partridge, the Forensic Tech as Red John based on the following theory:

In the episode where Bosco and his team got dispatched, Red John asked Rebecca to finish off the team she is working with. When Teresa took over the case, she urged Van Pelt and Rigsby to check out the surveillance cameras. At a certain moment, you could see Rebecca walking up the stairs with a tray of coffee, followed by a mystery man (which I credited him as "The Mystery Man" in my blog") That man was wearing the typical garments worn by Forensic Techs, windbreaker with FORENSIC lettering at the back...

hi im taylor. my theory is more like a fact. 
bret patridge is red john. evidence you say? well, in an episode jane was captured by some idiots and tied him up to a chair attempting to kill him acting like red john. and red john knew this was comming and he killed the people and ended up saving jane. he spoke to jane earlier in person but as his normal self. patrick jane didnt suspect a thing from him. but his voice gave EVERYTHING away!! i love this show. and there is proof on you tube. go tis url.
