And they have the perfect bait --- Detective Kara Quinn, who bears an uncanny resemblance to the targeted women.

When their plan works and they arrest the predator, Matt sends the rest of the team home. But on Monday morning, the couple doesn’t show up to work, and the MRT learns they never checked out of their hotel.
