— Tapp convinces Sing to invade the factory[src]
The factory was a large multi-story building located at 213 Stygian Street. It was originally used for the production of store window mannequins, but was closed at some point. After that, it was used by K2K, a criminal street gang, which controlled a small territory at 118th Street. They used the abandoned factory as a base and marked it with several gang tags. However, they eventually abandoned the building. (Saw)
After some time, it became the new hideout of John Kramer, better known as the Jigsaw Killer. John used the upper floor as his workshop, where he built his deadly traps and recorded the instruction tapes for his victims. Therefore, the upper floor, which was divided into two separate areas, was full of technical devices. It was also the place, where he made the final preparations for the game of Amanda Young, a heroin addict. (Saw, III)
When Amanda passed her test and thereby became the first person who ever won one of Jigsaw's games, Jigsaw targeted his next victim, Jeff Ridenhour. After abducting him, Jigsaw took Jeff to his hideout and strapped him to another one of his traps, a chair with two drills pointing at Jeff's head. (Saw)
Upon Amanda's survival, the police searched the crime scene of her game and eventually found a video recording of a mechanical ventriloquist puppet, which had been used by Jigsaw to deliver Amanda the rules and instructions to survive her game. Upon further examination by Detective David Tapp and Detective Steven Sing, the latter eventually recognized an old graffito by K2K in the background, which ultimately helped them to deduce Jigsaw's hideout.
Minutes later, Tapp and Sing arrived at the factory. Armed with a shotgun, Sing broke through the front door and entered the building, followed by Tapp, who gave him cover. Upon going upstairs, they found the K2K graffito and recognized it as the same one from the video. When they searched the hideout, they found a box with little figures resembling another deadly game Jigsaw had already planned for the future. Furthermore, they found one of the pig masks he used for his abductions, as well as the puppet from Amanda Young's video. Moments later, they were attracted by a noise nearby coming from under a large red hood. Eventually, this turned out to be the voice of Jeff Ridenhour, who was still strapped to the Drill Chair. However, when they wanted to free him, they suddenly heard the elevator, and Tapp told Sing to go into hiding to see what Jigsaw was going to do. Eager to finally arrest the Jigsaw Killer, Sing initially refused to follow Tapp's order, but eventually decided to do so and put the cloth back on Jeff before quickly going into hiding with Tapp. (Saw)
Moments later, a hooded man, Jigsaw, arrived and approached Jeff. When he told Jeff that he had planned a bigger test for him, the detectives came out of their hiding spot and held Jigsaw at gunpoint. However, the latter managed to activate Jeff's trap, which caused two drills to approach his head, giving the detectives merely 20 seconds to save him. While Tapp took care of the killer and held him at gunpoint, he demanded Jigsaw to tell Sing how to stop the trap and was told that only a key could unlock the metal neck brace, which held Jeff's head in place. When Sing found a set of keys in a box, he desperately tried to find the right one among the dozens of keys.
Having only a few seconds left, Sing decided to shoot the drills, saving Jeff's life in the process. However, Tapp was distracted by the gunshots, giving Jigsaw the chance to slash his throat with a hidden blade. As he ran away, Sing immediately pursued him and eventually managed to shoot him in a hallway, causing him to collapse. Thinking that Jigsaw was dead, Sing approached him but unwittingly walked right into a booby trap and was fatally wounded by four shotguns. After Sing's death, Jigsaw, who wore some kind of body armor under his cloak and therefore remained unharmed by the shot, stood up and left the hideout, leaving the detectives and Jeff behind. Moments later, Tapp, weakened by his injury, found the corpse of his dead friend and partner. Later that night, Tapp and Jeff were eventually found and saved by the Metropolitan Police Department, while Sing's body was taken to the morgue, where Dr. Adam Heffner performed the autopsy on his body. (Saw, VI)
In other Media
The events surrounding Sing's death are mentioned numerous times in Saw: The Video Game. While making his way through the abandoned Whitehurst Insane Asylum, Tapp, who was the game's protagonist and had to play one of Jigsaw's games on his own, found an audio recording of an emergency call made by Jigsaw only moments after Sing's death.
The events at the factory were also frequently mentioned in Saw II: Flesh & Blood through Tapp's files and tape recordings found by his son, Michael Tapp, over the course of his own game. According to these documents, none of the evidence found in the factory could've been used, as Tapp and Sing had invaded the building without a warrant. Michael also found a report by Detective Allison Kerry, who had informed her superiors about the events, and a letter by Chief Henry Jacobs, who discharged Tapp from the police force after the death of Sing. It was further revealed that Tapp initially didn't tell his colleagues the truth about the raid on the factory. However, he recorded a confession about his role in Sing's death. This recording was later found by Michael, who published the truth to get a job at a newspaper publishing company, therefore making him directly responsible for his father's discharge.
The raid on the factory, as well as Steven Sing's death, were both mentioned in the documentary Full Disclosure Report, hosted by TV moderator Rich Skidmore. The documentary focused on the early crimes of Jigsaw.
