Bret Stiles has got to be RJ. He is the only one with the charisma and power to have so many followers. We already know that he has a lot of friends in high places and he did get Lorelei out of jail. Lots of people think it is Kirkland but he didn't get PJ's info until after Lorelei was dead, so I think that excludes him. Actually, I think Kirkland is basically like PJ. Maybe RJ killed someone close to him, so he is out for blood too. Some think it is Partridge but I think he just enjoys his job or may be a serial killer himself but not RJ. Stiles may also be an old "Carnie" like Jane. The others just don't fit the profile for me. It has to be Stiles.
