Heller wants us off track.
Yet there are several things that could be big clues but because of there simplicity we can hardly see the forest for the trees.

I suspect Wayne Rigsby. Why?

1. He speaks Spanish. - The use of Y in "Tyger, Tyger"
2. Most of RJ's victims are women. - He acts awkwardly in front of women
3. His dad Steve Rigsby is a member of IRON Gods Motorcycle Gang and stayed in prison in Lompoc, the same prison as Jared Renfrew & Orville Tanner's.
4. He looks like the man in photo killing Carter Peak. (Am I really the only one noticed it at first glance?)
5. He was the sort of character whom you expect the least being RJ & he's been there from the very first episode.
6. He likes Grace Van Pelt who has red hair.
7. He is the 3rd man whom GVP fell in love with: 1st the madman outside the CBI and 2nd this madman O'laughlin & then there's Rigsby. (could be RJ - a madman too)
8. He imitates Patrick for a couple of times.
9. He pretends to be naive - perhaps really a good actor, our man RJ.
10. Last but not the least, according to Sophie Mille, RJ's a good whistle blower.. Does nobody ever remember in the Season 2 episode 2: Scarlet Letter there is this scenario:



"The Mentalist: The Scarlet Letter (#2.2)" (2009)


Kimball Cho: If she's a jumper, job's done.
Wayne Rigsby: Yeah. The senator's husband dumps her, she wants to make him feel bad
[Rigsby whistles]
Wayne Rigsby: splat.
Grace Van Pelt: Don't talk that way.
Wayne Rigsby: Okay not splat, bam.



Rosalind Harker's description of RJ could be misleading.

Rigsby's young but we never know the other side of the story.

And I can hardly recall there is this episode when Rigsby seems to have a phobia over something.. Gonna search for it.
