Facts from Bruno Heller:

1. Patrick Jane is not Red John

2. "We can trust that list" (list of suspects from Season 5 finale)


Facts we know from Lorelei

1. PJ shook his hand

2. He is a man (As he had a sexual relationship with Lorelei)


Facts from Rosalind:

1. Red John is about 6 feet tall ( which means that Gale Bertram is discluded)

2. Red John has straight short hair (not the case for Sherif Thomas Mcallisar)


Discluding the other suspects:

1. Bret Stiles: a litte smaller than the average and Too old for a sexual relation with Lorelei and Rosalind

2. Ray Haffner: Would be too obvious as he is only appearing for being a suspect

3. Bob Kirkland: WAAAAAAAAAY too obvious. And when he killled at the Hospital there was no Smiley.

4. Reede Smith: Too fat which Rosalind would have mentioned.


Do you remember season 1 Episode 1? Brett Partridge seems to be Close to an orgasm when describing how " red John " killed the victims. On top of that in the season 2 finale, Jane Comes back into the room and Kind of Shocks Partridge a Little bit which Red John does to Jane for revenge after the Tigre Poem.
The voice is very Close to Partridge as we can hear at the end of seasons 2 and 4. On top of that the voice sounds nothing like an older man ( Mcallisar, Haffner, Stiles, Bertram). You could argue that the voice is tricked through the mask and the mobile phone, but the Little Girl in season 4 tells Jane that RJ has a weird voice. Therefore it fits.

In conclusion: 4 suspects can be discluded 100% 2 others are unlikely. Brett Partrige would perfectly fit the role of Red John mainly due to his behaviour in Season 1, Episode 1.
I think that at the end Jane wont but Lisbon will shoot Red John rightfully.
