In the new episode of "Criminal Minds" Season 11, A.J. Cook will be back working with the BAU, but along with her return, the ruthless group of assassins will also make a comeback.

After her maternity leave, Cook will be back in the show as JJ, and according to Movie News Guide, JJ will be helping David Rossi's (Joe Mantegna) daughter, Joy (Amber Stevens West) look for a missing college girl. According to the report, Joy is now working as a journalist and she is depending on her father's team to find the missing girl.

Meanwhile, Christian Today also reported that the team will also be dealing with another problem as they received news that Giuseppe Montolo (Robert Neary) is now dead. Earlier, Montolo was the one who revealed to Derek Morgan (Shemar Moore) the location of the infamous assassin group, Dirty Dozen. The group has been under the authorities' noses for a long time, and it was only recently that their existence has been discovered.

It was revealed that Montolo was killed in prison after he confirmed the group's existence. Now the team suspects that members of the group were the ones who killed Montolo. Some of the members of the team are also convinced that there is a mole in the bureau, and now that their informant is dead, they will have a hard time locating the whereabouts of the group.  

In other news, it was reported that Jennifer Love Hewitt might also return to the show after her maternity leave as Kate Callahan. In addition, executive producer Erica Messer revealed in an interview that fans will also be seeing Cook's real baby like what she did with her first son Mekhai when he appeared as JJ's first son, Henry.

"Criminal Minds" Season 11 episode 7 will air on CBS on Wednesday.
