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.), an aug-only supermax prison also known as "Pent House."
Pent House Harvesting Operation Edit
By 2029, Junkyard has infiltrated Pent House. Taking advantage of the extreme social hostility against augmented persons following the Aug Incident, they manage to convince some 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. Executions must be signed by the prison warden, the head of security, and a professional doctor.
They sent in Hector Guerrero (who they knew as Oscar Mejia) and Ian Wilburg to oversee the operation. Guerrero and Wilburg would have Pent House's head of security 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 where Peter Wörthmüller strips 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. Guerrero 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, the corruption of the prison's head correctional officer, and that Wilburg had been murdered. Jensen makes contact with Guerrero, who refuses to return, claiming that the risk is not worth breaking his cover. Guerrero and Jensen are then attacked by Stenger and his men. Stenger had thought Jensen was sent to kill Guerrero 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. Guerrero, 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 Guerrero and assume his role as the leader of the operation, has Guerrero sent to solitary to await execution and attempts to befriend Jensen.
Jensen manages to make his way through the facility, finding more information about the operation and Guerrero's involvement. He manages to make it to solitary confinement and frees Guerrero. Depending on Jensen's actions, he may present evidence of Wilburg's murder and get Guerrero to confess. Guerrero will then claim that the murder was necessary as Wilburg had learned his real identity. In reality, Guerrero's murder of Wilburgh was to secure his position as the operation's ringleader. Guerrero sends Jensen to disable the prison's anti-aircraft security so they can escape by an aircraft. Stenger heads to the infirmary to protect Wörthmüller, as he was needed to harvest the augments. Unfortunately Guerrero 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 a threat. Jensen may resolve the confrontation peacefully or by siding with either Guerrero or Wörthmüller.
Due to the Pent House riot, Junkyard's harvesting operation is completely dismantled.
