‘Criminal Minds’ season 10, episode 16 preview: The case of the missing prisoner

What is Wednesday night’s new episode of “Criminal Minds” going to revolve around? We figure that the new sneak peek below should give you a pretty great idea of that.

In this preview, you get a better chance to see what the central mystery is going to be about: Someone is killing prisoners, and it is up to the BAU to try to piece together just who this someone is. Unfortunately, this is not going to be anywhere as easy as you would first assume that it would be … and for a variety of different reasons. For one, you have to figure out just where the main suspect is located. According to Reid in the new sneak peek video below, the prisoner this time around seemed to just vanish out of thin air a few months ago, and there are no further records of him. Therefore, someone is hiding within those walls, and figuring out a way to enact carnage on the inside.

This may not look like one of the most dangerous cases for the BAU to date, but it is for one simple reason: Tactical advantage. These are not people who are used to being behind bars, and therefore, they really don’t have the upper hand here at all. They run the risk of crossing over into enemy territory, and dealing with some not-so-pleasant things as a result of all of that.

Ultimately, we’d say to expect plenty of danger in this one, but also something a little different. It’s not often that you see a battle against the bad guys when they are already behind bars.
