CBI RON...this guy is ALWAYS there! I don`t know what to think - I don`t want him to be Red John, but he`s eligible for the position. He`s too quiet, kind and seems like he`s always willing to help. His presence freaks me out, he`s like a ghost: he`s at the CBI office, but sometimes, at the crime scenes, too. If he IS NOT RJ (and I hope is not), he definitely, definitely works for Red John! He seems so much like Rebecca, Bosco`s assistent and killer, so, my guess, he is also a psycho!

P.S. Given the fact that now the main subject on this site is Rebecca`s mysterious poisoning, I say this: IF the person who poisoned her is, in fact, Red John, the 7 suspects list reduces to Partridge (if we assume he cut his hair), Kirkland (if he painted his hair), and Haffner (if he painted his hair, too).
But my guess, it wasn`t RJ the person who murdered Rebecca, because she wasn`t alone when going to jail, so at least one of the guard would have recognized Partridge, Kirkland, or Haffner, who weirdly wore a police uniform. I think it was one of his disciples, so the question remains: Why is Rebecca looking at him like she`s in love with him, like he is Red John?
1. She never actually met Red John.
2. Red John is someone that`s not on the 7 suspects list.
3. Red John is someone working as a policeman, since none of the guards was surprised by his appareance.
4. Red John payed or manipulated all those guards to ignore him when poisoning Rebecca.
5.Red John is someone that Jane never met until episode 8, season 2. If he was able take a walk through the CBI departments without any fear, this means that he  and Jane never had a contact until that moment. Of course, if this is so, we can exclude Partridge, Sheriff McAlister, and Bret Siles from the list of suspects.
