Season 9 of Criminal Minds starts with the hunt for a methodical killer that takes the BAU to Arizona to search for an increasingly devolving UnSub, with speculations that the UnSub's ritualistic behavior is rooted in religion. The case leads them to a suspect that sheds light on a bizarre connection within the UnSub's family, which could ultimately lead them to finally capture the real suspect. Meanwhile, the team speculates that Hatch is in the running to be the new BAU unit chief. Guest stars for this season include Camryn Manheim, Fred Koehler, model Eva LaRue and more. And, Paget Brewster returns for the milestone 200th episode as we finally learn what "JJ" was up to when she was away from the team for a year. Season 9 also features the directorial debut of series star Joe Mantegna ("The Road Home").
