"Our BAU family is growing," Criminal Minds showrunner Erica Messer said in a statement. "We're excited to have Damon join the show and work alongside our amazing cast and crew."

Gupton will be joining the BAU with quite the law enforcement resume. In addition to his role on Bates Motel, the actor has played detectives on Empire, Prime Suspect, and Law & Order: Criminal Intent. As for his character on Criminal Minds, Gupton is sure to shake things up as seasoned profiler Special Agent Stephen Walker, coming to the BAU from the Behavioral Analysis Program of the FBI.

While the show's Sept. 28 series premiere left little indication of how Gibson will be exiting, it did introduce Adam Rodriguez's FBI Fugitive Task Force Agent Luke Alvez as another full-time member.
