'Criminal Minds' Season 11 Episode 4 Spoilers: The BAU Goes to Las Vegas, New Mexico to Solve a Robbery/Homicide Case

The Behavioral Analysis Unit (BAU) of the FBI is now headed to Las Vegas, New Mexico to find out who the killer is behind a robbery/homicide case.

In the last episode, which was directed by Joe Mantegna, fans saw Ashley Fink ("Glee") guest star as Dana, a florist who suffers from psychosis and killing three brides-to-be. Dana is caught up with her delusion that she and her sister's boyfriend-turned-fiancé are romantically involved, which caused her to kill all women that are "flirting" with him.

Viewers also saw broadcaster and NFL star Michael Irvin from the Dallas Cowboys visit the "Criminal Minds" set. According to Carter Matt, CBS is currently doing a cross-promotion between their shows and the NFL, like Thursday Night Football.

In the forthcoming episode of "Criminal Minds," which is entitled "Outlaw," the team heads to the country in Las Vegas, New Mexico. According to the synopsis posted by TV.com, the BAU team will investigate the murder of three restaurant employees, who were killed during a robbery. The website teased that the team would have to dig deep, since it might be related to a series of murders that happened six years ago.

A promo video was released for "Criminal Minds" season 11 episode 4 on YouTube, and viewers saw the deaths of a 17-year-old senior and a 16-year-old junior in high school. Dr. Spencer Reid (Matthew Gray Gubler) said on the video that the killers wanted the teens to "see each other" while being killed, in which David Rossi (Joe Mantegna) replied, "Not see, watch."

The full summary reads, "Three restaurant workers are killed during a robbery in Las Vegas, N.M., and it prompts the BAU to reopen a cold case that occurred in the town six years earlier."

New episodes of "Criminal Minds" air every Wednesday on CBS.
