Hitman Network

The Hitman Network (exact name unknown) is a network of hitmen that appeared in Season Eleven of Criminal Minds.

Background
Absolutely nothing is currently known about the network, other than it has five members, appears to have a strong online presence, and has a large number of clients. It has been said to have cropped up in 2013, following the downfall of the darknet Silk Road organization at the hands of the FBI. At some point after its founding, the group abducted a computer-savvy teenager named Barry Winslow and had him set up their network.

The Job
The network made its first appearance with a member named Giuseppe Montolo, who went on a string of independent killings across the U.S. in search of the client who ordered his unsuccessful hit. During its investigation, the BAU realize that Montolo is part of a larger network of hitmen working together. After Montolo is taken into custody, Morgan visits him at the hospital and warns him that they will find the rest of his team. Montolo gives Morgan the information of his next targets, dubbed "The Dirty Dozen". Afterwards, he pulls out his stitches to tell the agent that he will never stop them.

Target Rich
At the beginning of the episode, Morgan visits Montolo in ADX Florence to interrogate him. Montolo begins to talk, but as he does, he coughs heavily. He tells Morgan that there are four other hitmen in the network and "The Dirty Dozen" is not a person, but an object. When Morgan wants to learn more, Montolo coughs again, this time coughing out blood. Morgan calls for a medic, but when he does, Montolo dies. It is revealed that Montolo was poisoned by a prison guard, who was later found dead from a gunshot wound. At the end of the episode, it is revealed that "The Dirty Dozen" is Garcia, as she investigated them in the deep web during Montolo's case and was subsequently perceived as a threat by the network. As a result, Garcia is relocated to an old office in the BAU headquarters in Quantico.

Internal Affairs
When the Libertad Cartel begins targeting undercover DEA agents trying to undermine its organization, NSA Director Brian Cochran, the cartel's leader, orders the hit of Assistant DEA Director Bernard Graff, which is carried out by a member of the network called Zac Rubonis. Afterwards, Cochran is arrested and Hotch retrieves the flash-drive containing the access codes to the Libertad Cartel servers.

Entropy
In addition to the access codes, the flash-drive gives the BAU the information on members of the hitmen. They conduct a raid at a safe-house owned by the network, during which the Sniper and another member called Barry Plyman are killed. Barry Winslow, a teenager who was abducted by the network to serve as their technical analyst, is rescued. They find another member of network, Cat Adams. Reid goes undercover to meet her, but the BAU walk right into a trap she set up with the other remaining member of the team, Sharon Mayford. Cat holds Reid hostage while the Bomber plants bombs capable of blowing up the whole city block and killing thousands. However, Morgan and Lewis are able to subdue the Bomber and disarm the bombs. Afterwards, they are able to prevent Cat from killing Reid by saying her father (who she had been tracking down in an effort to kill him) is outside. They escort her into an armoured van and handcuff her as she realizes she had been tricked.
