Criminal Minds Sneak Peek: This Week's Unsub Has a Big Connection to an Old Case

Criminal Minds is doing another throwback in the last episode before the end of 2018. TV Guide has a sneak peek at Wednesday's case, and even though it's quick it provides a lot of information about the BAU's latest investigation.

In our clip, JJ (AJ Cook) tells Prentiss (Paget Brewster) that the team has seen these crime scenes before, just with a different twist. This week the unsub is killing men, but they are being dumped in the same way a serial killer in Milwaukee was killing women 11 years ago. The case that JJ references in the clip (after digging through the Criminal Minds archives) was Season 3, Episode 2, "In Name and Blood," where a man used his young son to help him lure women before he tortured them and cut out their hearts.

It's probably no small coincidence that men are being dumped in the same fashion and Wednesday's episode is titled "Flesh and Blood." Perhaps our young, unknowing unsub apprentice from over a decade ago has grown up to be a serial killer just like daddy? Start speculating now!

Criminal Minds airs Wednesdays at 10/9c on CBS.
