Last week, the BAU dealt with two criminals – one killed his cheating wife and the other witnessed the crime but opted against turning him in and instead used him for his own sinister plan that involves the FBI at the receiving end. Dr. Tara Lewis was a big help in closing down this case.

Next week's "Criminal Minds" season 11 episode, very accurately titled "'Til Death Do Us Part," will see the BAU tackle a case involving the murder of two women, who were set to walk down the aisle and marry the men they loved. The crime was perpetrated the night before they were to say "I do."

The team feels like the person behind the killing is someone one of these girls broke up with but just couldn't get over it. What better way to make every bit of the killer's seething wrath felt than by murdering the two on the eve of their weddings.

With "Criminal Minds" season 11 short of two major characters, the series has continually been bulking up with recurring characters and guest stars. This episode is no exception, with three personalities gracing the installment.

The lineup starts off with NFL Hall of Famer Michael Irvin, who will appear as himself. His appearance in the series has long been revealed with a promo still featuring the sports star making the rounds even before the season premiere.

Ashley Fink, who many will recognize from musical drama series "Glee," will also be in this "Criminal Minds" season 11 episode as a florist named Dana Seavers. Lastly, Chicago radio personality Mancow Muller is guest starring as a DJ.

This episode is also special in the sense that Joe Mantegna is both working in front of and behind the camera. The actor will appear as his character David Stephen Rossi in the episode but he gets to sit on the director's chair too.

"Criminal Minds" season 11 episode 3 "'Til Death Do Us Part" airs Oct. 14 at 9 p.m. on CBS.
