At the station Angie Garza, Fitch, Kraus, Drury, O'Brien, and Morgey try to find out who killed Boz. Zeke revives a box from the killer with USB in it Zeke plugs it in. They find the first video tape from the killer, who identifies the murdered man as a police officer. The killer plans to reform the Metro PD and remind them of the oath they took to the city. Schenk, Banks, and Detective Fitch piece together that the Jigsaw Killer has a new copycat. Once Zeke saw the video that Schenk anonymously sent to him in the form of an USB, he recognized the courthouse that appeared in the video, went there along with William and found the red spiral. Suddenly, two other cops that also watched the video, Fitch and Kraus. Zeke and William arrived at the crime scene, Detective Fitch and Detective Kraus, arrived at the scene too. William asked what they were doing there to which Fitch replied telling that they thought they would need some backup. Ezekiel insulted Fitch, telling him this wasn't his case. William told Zeke about the box that was in the metal bars of the windows of the building. Zeke leaped, grabbed the box and unpacked it. After opening it, inside they found Bozwick's tongue along with his plaque. All of them reacted with disgust, except for William who was once again faking it. Zeke then grabbed the police plaque and read the numbers. William asked Zeke who was the officer 4-5-3. Zeke got shocked after recognizing the numbers from the plaque and it was confirmed to him and the rest of the Metropolitan Police Department that Marv Bozwick was the one who was killed in the trap.

Detective Fitch and Detective Deborah Kraus went to the pawn shop witch when he did the owner told Fitch they were closed Fitch showed him his badge the man then let Fitch inside to look at the security cameras Fitch saw Boz chasing a man dressed as Uncle Sam and realized the man was Benny Reitz and that he lived at a bread factory. Fitch decided that he would go there and look for Benny Kraus asked if Fitch if they should tell Zeke about this Fitch replied and told her not to. She then left the pawn shop Fitch asked the owner if he could see one of the guns and took it with him Detective Fitch is abducted and later put into a trap were he must rip off their fingers before the water made contact with the exposed wires, or else he would be electrocuted to death. Fitch wore a cage-live device on their head which placed two small bars inside their mouth the Fitch bite down on the bars to start the motor which would slowly turn the mechanism, pulling the Fitch's hands (and by extension their fingers) towards the mechanism. As the mechanism turned, the metal bar placed on the table would eventually prevent the victim's hands from physically moving forwards, meaning that continued activation of the mechanism would eventually rip the victim's fingers off. However Fitch didn't rip his fingers off in time before the water made contact with the exposed wires and was then electrocuted to death. Zeke, Will and Kraus then find Fitch's corpse at bread factory the location of the crime scene. Drury suspects that Banks is involved since both Boz and Fitch had connections to Banks. Schenk, however, agrees with Banks that someone else is pulling the strings and puppet mastering the events around them. William remains the only cop who believes Banks. (Spiral)
A box is later delivered to the station with a taunting note asking Banks if the killer was getting under his skin. Inside the box is a piece of Schenk's skin under a puppet inside the box. Zeke identifies the via a distinctive tattoo. Also inside is a vial that directs the new batch detectives to a butcher shop. Banks recognizes the place as a hobby shop that he and his father visited when he was younger. After Ezekiel and O'Brien arrived at Constantine, along with numerus other officers Ezekiel and O'Brien entered the room where Benny's body (Who was still believed to be William's) was being examined by other cops including Barrett and Jeannie Lewis and reacted with horror and disgust after seeing the corpse.
Sometime at a shop one day Officer Barrett was attacked by a Figure in a Pig mask and was stabbed in the arm. He was later found by fellow officers and informed Detective Ezekiel Banks. Barrett's attack was used as a distraction to get the officers out of the precinct so that the killer could capture Captain Angie Garza. Garza is abducted and placed under the police station. Banks realizes she's been abducted and is next on the copycats kill order, and tries to find her. He doesn't arrive in time and discovers her corpse; her face is covered in wax, while her spinal cord is severed. Her death devastates Banks, but also gives him a lead. He realizes that the killer must know intimate knowledge of the police station to pull off the abduction. Banks also learns that his father, Marcus Banks, is officially missing as no one can locate him. Detective O'Brien suspects that Marcus is working with the copycat killer. (Spiral)
