"Criminal Minds" season 10, episode 9 spoilers reveal a new UnSub who who lives a conflicted life, as a BAU member will get a shocking news concerning a daughter.

In the promo clip for the next episode, the UnSub is a wife and mother who "appears rational at times" but is actually hiding a very terrible secret. The UnSub has trouble dealing with stress and anger, which makes her do unspeakable things.

In one of the crime scene, the dead victim appeared to be sleeping peacefully. It turns out that the UnSub has been "re-dressing" the victims, which prompts David Rossi (Joe Mantegna) to quip, "At least our UnSub's considerate."

At the end of the "Criminal Minds" season 10 episode 9 spoiler clip, however, a member of the BAU team will get a shock when a young woman turns up to say, "I'm your daughter."

The synopsis reveals "Criminal Minds" season 10, episode 9 spoilers as it reads: "The BAU investigates random murders in northern Virginia and searches for a conflicted UnSub who has an uncontrollable urge to kill but is also filled with remorse. Meanwhile, Rossi receives a visit from a woman who could hold a secret from his past."

"This episode should be very interesting to watch, but at the same time, we're also unclear just how interesting this case is going to be after a few minutes of it," said Cartermatt. "Therefore, we're a little bit more interested in the Rossi story, given that the more we learn about this character, the happier we will be in the end."

The guest stars for this episode feature Tina Holmes of "Six Feet Under" playing architect Ellen Connell, and Amber Stevens of "22 Jump Street" as Joy Struthers.
