The Behavioral Analysis Unit (BAU) will take on the challenge of locating a missing college student in the upcoming episode of the CBS series "Criminal Minds."

In "Target Rich," Cartermatt reports that David Rossi's (Joe Mantegna) daughter will ask the specialists' help in finding the coed who suddenly disappeared without a trace. Joy (Amber Stevens West), who now works as journalist, has complete faith in her father's team to provide answers on what happened to the student. While BAU is busy assisting Joy, bad news will arrive in the form of Giuseppe Montolo's (Robert Neary) death.

Montolo was the one who revealed to Derek Morgan (Shemar Moore) the whereabouts of the "Dirty Dozen." The new villain in town was a group of hitmen who has so far avoided detection of the authorities until now. According to the news, Montolo died in prison directly after he revealed its existence.

More and more, the BAU operatives are becoming convinced that there is a traitor in their midst. With the informant's death, it has become difficult to get another trace of the underground group.

Meanwhile, Jennifer Jareau (A.J. Cook) is back from her maternity leave. While Dr. Tara Lewis (Aisha Tyler) did her best to fill in for her, the team will certainly feel the ease of working with an old comrade. JJ's presence is sure to boost everyone's confidence with this new case. In a short while, Kate Callahan (Jennifer Love Hewitt) will also return from her own leave. It will not be long until viewers see a complete BAU once again.

Last episode, a woman was murdered in town purely inhabited by sex offenders, which make it a hundred times difficult for BAU to apprehend the killer. The victim was found wearing a cheerleader uniform. While evidence pointed to her husband doing the crime, an eye-witness was able to provide the team a new lead. Apparently, a killer who had fantasies involving peplums was on the loose. He next targeted the sheriff's daughter, who was once a cheerleader. Fortunately, BAU saved the girl before the culprit could hurt her.

"Criminal Minds" airs Wednesdays at 9 p.m. EST on CBS.
