Not much is known about Junkyard. Originally, Interpol thought it was a relatively small-time black market organization that dealt in drugs and small arms, but in A Criminal Past, it is revealed that Junkyard also runs an augmentation harvesting operation out of Penley T. Housefather Correctional Facility (P.T.H.C.F.).
P.T.H.C.F. Harvesting Operation Edit
In 2029, Junkyard has infiltrated P.T.H.C.F., an aug-only supermax prison also known as "the Pent House." Taking advantage of the extreme social hostility against augmented persons following the Aug Incident, they manage to convince most of the facility's correctional officers to work with them. They exploit the prison's Terminal Violation Policy system, which gives prison authorities the power to deliver 24-hour execution orders if an inmate has committed infractions that fall under Terminal Violation classification.
They sent in Hector Guerrero (who they knew as Oscar Mejia) and Ian Wilburg to oversee the operation. Guerrero and Wilburg would have P.T.H.C.F.'s warden Thomas Stenger and his officers claim that certain inmates (targeted for valuable augmentations they have) had made a large enough violation to be scheduled for execution. The inmates were then sent to solitary confinement to await their deaths. Once executed, the corpses are taken to the infirmary and Stengar forces Peter Wörthmüller to strip them of their augments without damaging them. The augments are then smuggled out to Junkyard and sold on the black market, with the collaborating officers getting a nice cut of the profits.
Initially, Interpol is unaware of Junkyard's harvesting ring. This changes when Interpol send in Adam Jensen, undercover as an inmate, to make contact with Guerrero in order to bring him back to HQ to confirm a possible terrorist threat. Hector had spent years working his way up the ranks of Junkyard, steadily feeding intel on the gang to Interpol until he broke communication to keep from being found out.
During the course of his infiltration, Jensen uncovers the harvesting plot, corruption of the prison's correctional officers, and that Wilburg had been murdered. Jensen makes contact with Hector, who refuses to return, claiming that the risk is not worth breaking his cover. Hector and Jensen are then attacked by Stenger and his men. Stenger had thought Jensen was sent to kill Hector and thus ruin the operation.
The operation came to an end thanks to a riot sparked by another inmate, Frederick Flossy. The augmented inmates, using powerful painkillers to negate the pain of the prison's anti-aug security measures, took up arms against the prison guards in revenge for the abuse and murders. Hector, realizing that the operation is now unsalvageable, tricks Stenger into believing Jensen is another high ranking member of Junkyard in order to save his life, so that he can escape back to Interpol. Stenger, seeing his chance to kill Hector and assume his role as the leader of the operation, has Hector sent to solitary to await execution and attempts to befriend Jensen. Jensen manages to make his way through the facility, finding more information of the operation and Hector's involvement. He manages to make it to solitary confinement, free Hector, but presents the evidence of Wilburg's murder and gets Hector to confess. Hector claims that it was necessary as Wilburg had learned his real identity, but in reality it was to secure his position as the operation's ringleader. Hector sends Jensen to disable the prison's security so they can escape. Stenger heads to the infirmary to protect Wörthmüller, as he was needed to harvest the augments. Unfortunately Hector has sneaked into the infirmary and kills Stenger, both as revenge for attempting to usurp him and to cover up his part in the operation. He also forces Wörthmüller up to the landing pad and tries to convince Jensen that Wörthmüller is the real ringleader. Jensen refuses to let Hector execute Wörthmüller and eventually makes Hector confess to his involvement. Hector admits that he would no longer be able to return to his previous life. He then attempts to kill Jensen, so he can take the prison's transport and rejoin Junkyard. Jensen then either kills Hector, knocks him out and leave him, or knocks him out and arrests him to be brought back to Interpol.
This completely dismantles Junkyard's operation in P.T.H.C.F. and informs Interpol that they are a much larger threat than originally thought, firmly putting Junkyard on Interpol's radar.
