In the next episode of "Criminal Minds," the Behavioral Analysis Unit (BAU) led by Agent David Rossi (Joe Mantegna) investigates a string of murders connected to a police chief in Virginia.

The trailer and promotional photos for the upcoming installment, which is titled "Full-Tilt Boogie," were just recently released, and they show Rossi, Matt Simmons (Daniel Henney), Dr. Tara Lewis (Aisha Tyler), and the rest of the team discussing the case in their headquarters.

Simmons tells the team that there have been 15 deaths already, and the toll could increase even more if they do not get to the bottom of it. They then head over to the small town in Virginia where the murders are taking place. Rossi and Luke Alvez (Adam Rodriguez) can be seen at a bridge surveying the crime scene of a recent homicide.

They soon discover that the murders are connected to the police chief in the small town. Rossi looks at a picture of the unassuming police official with his wife and two children. "Everybody is keeping secrets," Jennifer Jareau says to the team as they realize that things may not be what they seem.

Later, the wife of the police chief enters her bedroom, but the door suddenly closes from behind her. She turns around and is shocked by who she sees. It remains to be seen if the husband has anything to do with the murders.

In the last episode, the team investigated a series of murders that took place in backyard swimming pools. They were able to catch the killer who happened to have a traumatic experience when he was younger. Apparently, his friend drowned and ever since then, the killer felt tremendous regret for his death.

"Criminal Minds" season 13 episode 11 will hit the airwaves on Wednesday, Jan. 10, at 10 p.m. EST on CBS.
