Episode 3 of "Criminal Minds" Season 11 found the BAU investigating the murders of several women who were killed on the night before their weddings. Titled "Till Death Do Us Part", the episode was directed by Joe Mantegna, who plays the veteran FBI profiler David Rossi in the series.

The unsub was seen usually giving the victim a blow to the head. The victim was then brought to a basement where she is strangled to death. The team at first had a difficult time nailing down the profile of a man who was supposedly the killer of the brides-to-be only to realize later on that the killer was a female after all reports  Christian Today.

It turns out that the unsub (unknown subject) was a mentally ill and delusional woman named Dana Seavers according to Ecumenical News. She was a florist who believed that wedding photographer Ryan Becker was in love with her but in reality, he was interested with her sister. Dana imagined that Ryan was telling her to kill the women and she confessed that she only did what Ryan told her to do.

The episode also showed viewers a glimpse of Morgan, Tara and Rossi's relationship. It was later revealed that Tara is engaged but is in a somewhat complicated relationship.

Meanwhile, in episode 4 titled "Outlaw," the Behavioral Analysis Unit (BAU) goes on a trip to Las Vegas, New Mexico. The synopsis for the episode which will be aired on October 21 in TV.Com, relates how the BAU is sent to investigate a robbery/homicide that happened at a Las Vegas restaurant. The incident will prompt the team to re-open a murder case that happened six years ago which is believed to be connected to the latest killing.
