Viewers got to see a grisly killer who made murder victims as part of a street art in the latest episode of "Criminal Minds" season 11.

In episode 5 titled "The Night Watch," which aired just this week, the Behavioral Analysis Unit (BAU) was headed to Detroit to find the artist/serial killer, whose motive was driven by the loss of a child.

The real street artist was discovered to be a woman who was being framed by the serial killer because of a past both have shared.

Meanwhile, the episode also highlighted Dr. Tara Lewis' (Aisha Tyler) story, particularly her struggle to find time for her fiancé Doug Fuller (Robert Kirkland).

Just like the story of how Aaron Hotchner (Thomas Gibson) and deceased wife Haley (Meredith Monroe) didn't work out in the earlier seasons of the show, the same thing happened with Tara who gets caught up with work that she barely has time for Doug.

Meanwhile, Tara's personal issues may get in the way of her work and could ultimately lead to her exit from the show.

According to a report from Carter Matt, Tyler's character may soon be exiting the show because of two things: one is that the actress has several TV projects, which makes her a busy woman and the other is that A.J. Cook, who plays J.J., will return in episode 7.

This doesn't mean that viewers have seen the last of Tyler and her character; she might stick around for a while, but given episode 6's synopsis, it could signal that the particular episode will say goodbye to Tyler.

"Lewis receives a career opportunity that may take her away from the BAU," the official synopsis states.

With J.J. returning, it won't be a surprise if Tara gets written off. However, there's also a possibility that Tyler will make guest appearances in the coming episodes.

In the upcoming episode 6 of "Criminal Minds" titled "Pariahville," the team will head over to a small town in Florida to investigate the murder of a woman.

The team will also face challenges during the investigation as the town residents are mostly composed of sex offenders, giving the BAU a long list of suspects.

"Criminal Minds" season 11 airs Wednesdays at 9 p.m. EST on CBS.
