On this nail-biting episode for "Criminal Minds" Season 12, she will help Aaron Hotch to investigate and hunt down the murderer. The scene is expected to be suspense-driven leaving the whole search operation team perplexed as they try to trace the modus of the killer.

Fighting against time, the BAU is doing every possible way to crack this case. The big question is, are they dealing with a monstrous human being or a strange creature?

Other news indicates that fan favourite character Aaron Hotchner played by Thomas Gibson will no longer be part of the show. According to reports, the actor was fired after he had an argument with the show's writer. International Business times reported that Episode 2 was the last appearance of Gibson in the long-running series.
