What tv series did Jackson guest estrela on and who did he play?

He guest starred on an episode of Criminal Minds as a serial killer who suffered from multiple personalities. His real name was Adam. Adam's personality was shy, reserved, and avoided confrontation. His other personality, a girl named Amanda, was the one responsible for the killings. Amanda raped and killed several alpha males who reminded her of Adam's abusive stepfather. The episode ended with Amanda trying to kill Adam's stepfather, but Dr. Reid talked her out of it. Instead, she took over as the only personality in an effort to protect Adam forever.

Yeah it were criminal minds but i have to track down the episodes :L

He also played in The O.C. as Justin, in Beautiful People as Nicholas Fiske, Close to início as Scott Fields and The cleaner as Joey.
I liked him in all of it but his atuação skills are really showing in The cleaner and Close to home.
