Detective Steven Sing is a fictional character from the Saw franchise. He serves as a supporting protagonist in the first Saw film.

He was portrayed by Ken Leung.


Cecil Adams' Death

Steven Sing was a homicide detective who worked for the Metropolitan Police Department. At some point in his career, Sing got involved in the investigation of a serial killer case. The first victim was a drug addict named Cecil Adams, who died of blood loss after falling into a cage filled with razor wire. He had eight parallel cuts on his face, and a jigsaw piece had been cut from his skin, leading to the killer being nicknamed "Jigsaw." Due to Cecil's unusual way of death, Sing was assigned to a task force along with Detective David Tapp, Detective Allison Kerry, Detective Mark Hoffman, and Detective Fisk. (Saw, Saw V)

Seth Baxter's Death

Sometime later, another victim of Jigsaw was found in a deadly trap. A man named Seth Baxter had been cut in half by a giant pendulum-shaped blade. Additionally, both of his hands had been crushed by two mechanical vises. It turned out that the man used to be the boyfriend of Detective Hoffman's sister, Angelina Acomb. During a domestic dispute five years earlier, Seth killed her and was sentenced to life in prison. However, he was released one month before his death due to a technicality. Due to Hoffman's personal connection to Seth, Kerry undertook the investigation. (Saw V)

Paul Leahy's Death

Tapp and Sing investigate Paul's death

The next victim that was found was a 46-years-old drug addict named Paul Leahy. Jigsaw had chosen him to participate in one of his gruesome games because Paul had sliced his wrists earlier, not because of depression but rather to attract attention. Therefore, Jigsaw had taken him to a cellar. The back part of the basement area was fenced-in and, thereby, basically turned into a cage. This cage was almost entirely filled with razor wire. Upon examining the crime scene, the investigators found an audiotape, which Jigsaw had left for Paul. According to the tape, Paul was supposed to crawl through the razor wire to reach the exit door and save his life. However, the wounds he received in the process were so severe that he ultimately died of blood loss. When Tapp and Sing arrived, Kerry presented them with the recording. Furthermore, she found a peephole in the door to the adjacent room, indicating that Jigsaw had been present during Paul's game and watched his demise. (Saw, Saw IV, Saw V)

Mark Wilson's Death

Shortly afterward, the detectives were called to another crime scene. The victim, a man named Mark Wilson, had been trapped inside a dark room with the only light source being a single candle. Furthermore, he was injected with a slow-acting poison and was informed by an audiotape that the only antidote was inside a safe. To save himself, Mark had to find the correct combination among hundreds of numbers written all over the walls. This task was made even more difficult by the fact that the entire floor was covered in broken glass shards. Additionally, Mark's body was slathered with a jellylike, flammable substance. When walking around the room with the candle, Mark accidentally ignited the jelly, causing him to burn alive. While investigating the crime scene, Kerry noticed another peephole in one of the walls and informed Tapp and Sing that she had already found a similar one at the place of Paul's death. Furthermore, the detectives found a penlight and immediately sent it to the forensic lab. Shortly afterward, the results came in, and the fingerprints were identified as those of Dr. Lawrence Gordon, a renowned oncologist. (Saw)

Amanda Young's Survival

Soon after Mark's body had been found, Amanda Young, a drug addict, came to the police station after escaping one of Jigsaw's games. After a doctor examined her wounds, she was interrogated by Detective Tapp. Amanda told him how she had woken up at an unknown location and found herself strapped to a chair. While she was unconscious, Jigsaw had put a mechanical device on her head, which was hooked into Amanda's upper and lower jaw. Amanda had received her instructions from a mechanical ventriloquist puppet, which spoke to her via a video recording. The doll described the device on her head as a "reverse bear trap," which would rip her mouth open if she didn't manage to free herself within 60 seconds. Therefore, she had to cut the key to the device from the stomach of her supposedly dead cellmate, Donnie Greco. When the tape ended, Amanda was able to free herself from the chair and ultimately obtained the key by disemboweling her fellow prisoner, who was, in fact, still alive at that point. (Saw)

First Suspect

Tapp and Sing visit Gordon at the hospital

Detective Tapp and Detective Sing immediately went to the Angel of Mercy Hospital, where Lawrence Gordon was working. They asked him about his whereabouts on the previous night between 11 o'clock and 1 o'clock. When Gordon asked Tapp for the reason of that question, the latter showed him the penlight with his fingerprints on it. Gordon was taken to the police station for further interrogation. On the advice of his lawyer, Brett, he told the officers that he had met up with one of his medical trainees, Carla, with whom he had an affair. Even though his alibi was confirmed by Carla, Detective Sing asked him to stay a little longer and listen to the interrogation of Amanda Young, whom they requested to repeat her testimony in Gordon's presence as they wanted to see his reaction. The doctor agreed and was visibly shocked as Amanda described her traumatic experience, and even more so when Sing told him that Amanda's fellow prisoner was still alive and merely paralyzed with an opiate overdose when she cut him open. After the interrogation, Tapp drove him home and made it abundantly clear that he still wasn't entirely convinced of the doctor's innocence. (Saw)

Jigsaw's Hideout

Tapp and Sing spot the graffito

Shortly afterward, Tapp further examined the video found at the scene of Amanda Young's game. When Sing was about to leave work, he asked him to go to the bar at the corner for an after-work beer with him and their colleagues, which Tapp declined with thanks as he wanted to continue his examination. Sing joked that Tapp should find himself a girlfriend before he left the room, but was held back by Tapp when the latter spotted a graffito on a wall behind Jigsaw's puppet. This graffito was associated with K2K, a small gang from 118th street. Besides that, Tapp heard a fire alarm in the background and, therefore, checked the recent fire reports for the area. With Sing's assistance, he ultimately found out about a fire in a rear house that was close to an abandoned mannequin factory. Although they didn't expect to get a warrant, the detectives left the police station and went to the factory.

Tapp and Sing invade 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 and examining the locations, 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 that the killer had used to visualize another deadly game, which Jigsaw had already planned for the future. Furthermore, they found a pig mask used by Jigsaw for abducting his victims, and the mechanical ventriloquist puppet that had given Amanda Young the instructions for her game. Moments later, they suddenly caught a sound coming from under a large red cloth. Upon investigating the noise, they discovered a man named Jeff Ridenhour, strapped to a mechanical chair by Jigsaw. However, when they wanted to free him, they heard a nearby elevator. Eager to finally arrest the killer, Sing initially refused to follow Tapp's order, who told him to hide until they got a better look at Jigsaw, but ultimately gave in. The detectives quickly put the cloths back on Jeff and the puppet and went into hiding. (Saw)


Sing's corpse

Moments later, Jigsaw arrived, disguised with a black cloak and hood. Tapp and Sing observed him as he approached Jeff and told him that he wanted to use him to test a bigger project. At this moment, the detectives left their hiding spot and aimed their weapons at Jigsaw. Jigsaw reacted quickly and activated the mechanical chair by stepping on a pressure button on the floor. Thereby, two drills started to approach Jeff's head from both sides. While Sing desperately tried to deactivate the contraption, Tapp held Jigsaw at gunpoint. Even though Jigsaw told them that the key to the trap was in a box next to Jeff, Sing couldn't find the right one in time as there were dozens of keys attached to the key ring. In the last nick of time, Sing saved Jeff nonetheless by shooting the drills. However, the shots distracted Tapp and allowed Jigsaw to slash his throat with a hidden blade and run away. Sing pursued him and shot him in a hallway, causing him to collapse. Thinking that he was dead, Sing approached his body and thereby stepped on a tripwire. This carelessness proved to be fatal as the wire triggered another trap, which caused Sing to be killed by four shotguns attached to the ceiling beam. Afterward, Jigsaw, who wore some kind of bulletproof body armor under his cloak, left the factory without any significant injuries. (Saw)


Tapp, who survived his injury, was saved later on, along with Jeff Ridenhour. However, he suffered a mental breakdown due to his role in Sing's death. Sing's corpse was then taken to the morgue, where Dr. Adam Heffner performed the autopsy on his body. After Jigsaw's death at the hands of Jeff Denlon, another one of his victims, Sing and his deceased colleagues - Daniel Rigg, Eric Matthews, David Tapp, and Allison Kerry - were given a memorial. A picture of him stood next to those of his colleagues. On this occasion, Detective Hoffman and the Chief of Police each delivered a speech to honor them and their efforts. (Saw III, Saw V, Saw VI)

Non-Canon Appearances

Full Disclosure Report

The raid on the mannequin factory and Sing's subsequent death were mentioned in the "Full Disclosure Report," a documentary focusing on Jigsaw's earliest crimes.


Steven Sing was one of the youngest detectives who worked on the Jigsaw case and therefore followed the orders of his longer-serving colleagues most of the time. He seemed to be very popular with most of his colleagues, including David Tapp. While he wasn't as obsessed with the case as some of his colleagues, he was just as eager as them to arrest Jigsaw and end his games. Due to his friendship with Tapp and the latter's working experience, he trusted him almost blindly, which was the reason why he agreed to enter Jigsaw's hideout without a warrant when Tapp said so without any hesitation.


  • According to Rich Skidmore, host of the "Full Disclosure Report," Sing was 28 years old when he died.
  • In an earlier draft of the script of Saw III, Jeff Denlon was supposed to pass the hallway where Sing was killed and find his rotting body, indicating that the police never discovered the mannequin factory after the events of the first film.
  • In the scene when he entered Jigsaw's hideout, Sing was played by Leigh Whannell as actor Ken Leung wasn't available at the shooting date.
