Detective Allison Kerry is a fictional character from the Saw franchise. She serves as a supporting protagonist in Saw, Saw II, and Saw III.

She was portrayed by Dina Meyer.


Cecil Adams' Death

Allison Kerry was a homicide detective who worked for the Metropolitan Police Department. As a classic workaholic, she developed an obsession with her work, which was one of the reasons why she had no contact with her family anymore. At some point in her career, Kerry 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, Kerry was assigned to a task force along with Detective David Tapp, Detective Steven Sing, Detective Mark Hoffman, and Detective Fisk. Unbeknownst to her colleagues, Kerry was in touch with the FBI and provided the special agents Peter Strahm and Lindsey Perez with information about their progress in the investigation. (Saw, Saw II, Saw IV, 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

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

Kerry discovers the peephole

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

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. Upon their arrival, the detectives requested Amanda Young to repeat her testimony in Gordon's presence as they wanted to see his reaction. The doctor 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. However, he was able to present them with an alibi for the time of Mark Wilson's death. During that night, Gordon had met up with one of his medical trainees, Carla, with whom he had an affair. When Carla confirmed his alibi, Gordon was allowed to leave. (Saw)

Steven Sing's Death

Sometime later, Detective Tapp seemingly achieved a breakthrough in the investigation. By further examining the video found at the scene of Amanda Young's game, he 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.

Minutes later, Tapp and Sing arrived and entered the building. Upon examining the location, they found the K2K graffito and recognized it as the same one from the video. When they searched the hideout, they suddenly caught a sound and discovered a man named Jeff Ridenhour, strapped to a mechanical chair by Jigsaw. However, when they heard a nearby elevator, they went into hiding. 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. Furthermore, he was discharged from the police force for invading Jigsaw's hideout without a warrant. After that, Kerry became the new leading investigator in the case. (Saw, Saw II)

Michael Marks' Death

Kerry and Eric at the crime scene

Several months later, Kerry was called to the murder scene of another Jigsaw victim, Michael Marks, whose corpse had been found in a basement during asbestos disposal. Michael had been forced to wear one of Jigsaw's traps, a so-called death mask. Within 60 seconds, Michael had to cut out his right eye to obtain the key, which had been surgically placed in his orbital cavity. Otherwise, the two halves of the mask, which were both spiked with nails, would close in on his head and kill him. However, Michael's attempts to save himself remained unsuccessful, ending in his death. When Kerry arrived, she found a message written at the ceiling, which said, "Look closer, Detective Matthews," referring to Detective Eric Matthews, her former partner with whom she used to have an affair. Their relationship had ultimately resulted in Eric's alienation from his son, Daniel, and his wife, who subsequently filed for divorce. The first officer who arrived at the crime scene told Kerry that Michael might have been one of Eric's informants. However, as he wasn't entirely sure about this, Kerry decided to call Eric for help. Although the latter wasn't happy to see her, he agreed to take a look at the corpse. Due to a tattoo on his leg, Eric was able to identify Michael as his informant. However, when he saw a jigsaw piece cut from Michael's skin and read the message Jigsaw left for him, he refused to help Kerry as he neither wanted to have anything to do with the case nor with her.

Back at the police station, the events at the crime scene resulted in an argument between them. While Kerry examined a video found at Michael's crime scene, which had been used to give him his instructions, Eric interrupted her and compared her to Jigsaw, claiming they had much in common as they both liked to play with other people. When Kerry apologized for her behavior at the crime scene and tried to convince Eric to help her, he reminded her that this was her case, and they were no partners anymore. Angered by this, she asked Eric when he stopped to be a cop before leaving the office. (Saw II)

Eric Matthews' Test

However, when Eric deduced the true meaning behind Jigsaw's message, he was able to locate the killer's hideout at the Wilson Steel Plant due to an engraving on the trap. The next day, Kerry, accompanied by Eric and a SWAT team led by Sergeant Daniel Rigg, went to the building and sent Rigg in with three of his men. While searching the building, the SWAT members triggered a booby trap, which caused two officers' death, while the third one, Officer Pete Baker, was severely injured. Called in for reinforcements by Rigg, Kerry entered the building with Eric and the remaining SWAT team. Moments later, they finally found the Jigsaw Killer, who was, in fact, a civil engineer and cancer patient named John Kramer.

Kerry and Eric find the monitors

Initially, Rigg ordered his men to arrest him. However, John spoke to Eric and told him that he should stay where he was until Eric had dealt with his "problem." Then, he told him to take a look in the next room, where he, along with Kerry and Rigg, found several surveillance monitors. Upon looking at the monitors, they saw what appeared to be another one of Jigsaw's games. Eight people were trapped in a room, one of whom Eric recognized as his son, Daniel. When he saw the footage, Eric angrily attacked John. However, he was held back by Rigg. John explained the rules of his game to him. Eric's colleagues had to leave the room while he only had to stay there and talk with John for two hours. After that time, Daniel would be released.

Kerry calls for the tech team

Kerry tried to calm Eric down. However, this attempt remained unsuccessful as Eric got more and more nervous, especially when the first victim, Gus Colyard, was killed by a booby trap a few minutes after the game began. On Rigg's advice, Kerry called for a tech team to trace back the video broadcast. After another brief talk with John Kramer, Eric told his colleagues about his ultimatum: To save his son, he just had to sit down and talk to John until the end of the game. Kerry argued with Rigg, who suggested to grill John about the victims' whereabouts by using violence. She told him this wouldn't work, stating that John fit a specific psychological profile. Eventually, she convinced Eric to agree to John's challenge and talk to him while she kept an eye on the game's progress. As he took a seat at John's table, Eric placed a walkie-talkie beneath his chair, so his colleagues could listen to their conversation.

Kerry learns about the people framed by Eric

When the second victim in the house, Obi Tate, died in another trap, Rigg repeated his suggestion to make John tell them about the location by violation as they were wasting time. Kerry, however, still insisted on keeping the situation calm as long as possible. Meanwhile, Eric became more and more distressed as the game went on, and the tech team was running late. Therefore, Kerry came up with another plan and advised Eric to provoke John by destroying his blueprints, notes, and drawings. However, as he did so, John was barely impressed by his fit of rage and death threats. While watching him calmly, he responded that Eric wouldn't be able to convict him if he destroyed all the evidence in his hideout. Eric finally stopped when the tech team arrived to trace the video broadcast to its source. When he decided to end his conversation with John, the latter told him to look in the drawer of one of his desks. Upon doing so, he and Kerry found the files of the prisoners in the house - Gus Colyard, Obi Tate, Jonas Singer, Laura Hunter, Xavier Chavez, and Amanda Young, the first known survivor of Jigsaw's games. Eric had wrongfully arrested all those people for crimes they didn't commit by faking the evidence in several cases. John mocked him and told him that Daniel would be in danger if his fellow prisoners learned about their connection.

Shortly afterward, Eric watched as Daniel was pursued by one of the other prisoners, Xavier Chavez, and therefore ultimately lost his composure. To force John to reveal his son's whereabouts, he violently battered him, broke one of his fingers, and threatened him with his gun. Kerry tried to stop him but was held back by Rigg. Therefore, John ended Eric's test with the words "Game Over" and promised to take him to the house. However, he demanded to go there with Eric alone. Eric agreed, and they left the building in a hidden elevator. As they escaped, Kerry sent the SWAT team after them while she stayed with SWAT Officer Joe and the tech team, which traced the video feed to an address at 237 North Hyde Crescent shortly afterward. However, when Rigg and his team arrived there, they realized the game had taken place in a different house and was already over long before they even arrested Jigsaw. Upon learning that the video feed was merely a recording, Kerry told the team to come back. As the timer eventually went off, a safe in John's hideout suddenly opened and revealed Daniel Matthews, who had been locked up in the safe all the time. (Saw II)


When Eric didn't return, his colleagues eventually concluded that he had become a victim of Jigsaw as well. Shortly after the game, Kerry found out, probably due to Daniel's testimony, that Amanda Young was, in fact, Jigsaw's accomplice and had merely pretended to have been tested again. Desperate to find Eric, Kerry began to feel guilty for his disappearance as she thought it likely wouldn't have happened if she didn't push him to help her. These feelings of guilt caused her to have nightmares in which she saw him, which worsened her emotional state even more. (Saw II, Saw III)

Troy's Death

Kerry at Troy's crime scene

Six months later, Kerry was called to an elementary school by Rigg. Following an emergency call about an explosion, Rigg and his team had raided the building and found the crime scene of another game, which the victim, a man named Troy, didn't survive. When Kerry arrived, she immediately asked if the victim was Eric, but Detective Mark Hoffman, who investigated the crime scene, told her it wasn't him. He also informed her that the victim had been held in place by eleven chains piercing his body and was eventually killed by a nail bomb. However, Kerry got suspicious when she learned that the SWAT team had to cut the door open as it had been welded shut, giving Troy no chance to escape even if he would've passed his test. This detail led her to the conclusion that someone else was responsible for the game. Seconds later, a member of the forensic team told her that the videotape containing the instructions for Troy's game was still intact, despite the explosion. (Saw III)


Eager to find Eric and finally put an end to Jigsaw's games, Kerry took the video from Troy's crime scene and a bunch of photos and files with her to continue her research at home. While she watched the video over and over again, she suddenly saw herself on the TV screen. Realizing that she was filmed from inside her closet, Kerry grabbed her gun and shot right through its door. When she searched the closet, she found the camera and removed it, but was then subdued by an invader with a pig mask, who snuck up on her. Amanda Young and Detective Hoffman, who was also an accomplice of Jigsaw, took her to an underground room and placed her in a deadly trap. Suspended above the floor by two chains, Kerry was put in a harness consisting of twelve metal brackets hooked into her rib cage. (Saw III)


When Kerry woke up again, she immediately realized what had happened to her and started to panic. Moments later, a TV turned on in front of her. Jigsaw's ventriloquist puppet appeared on-screen and revealed to Kerry that she was abducted because she was obsessed with her work to the point where she preferred the presence of a dead body over that of a living human being. It told her to grab the key to her trap from an acid-filled beaker hanging in front of her. Otherwise, the device would kill her after 60 seconds by tearing her rib cage apart.

Kerry grabs the key

When the tape ended, and the TV turned off, Kerry further panicked and tried to tip the acid out of the beaker. However, this wasn't possible as it was held in place by two chains. After some initial hesitation, she finally tried to get the key but pulled her hand back due to the massive pain. Nonetheless, she could bring herself to try it once again and eventually got the key from the glass, which she used to open the lock of her device. Unfortunately, the lock was without function, destroying her remaining hope to survive. Mere seconds before the timer expired, Amanda entered the room. Kerry recognized her and realized it was her who had manipulated Troy's trap as well as her own. Moments later, the timer went off, causing the contraption to tear her rib cage apart. (Saw III)


Four days later, Detective Hoffman, accompanied by a SWAT team led by Rigg and Officer Lamanna, were called to the location. As they entered the area, their path was blocked by a chain-link door. Upon spotting a device connected to the door, Hoffman told the SWAT to send in a tactical robot before entering. Rigg ordered Pete Baker to cut a hole in the door and send the robot in. The robot slowly made its way to the lower floor and soon reached Kerry's corpse, still hanging from the ceiling. When the camera of the robot eventually captured her face, Rigg immediately recognized his colleague. Horrified by the discovery, he broke through the door and ran to her, ignoring Hoffman's order to stand back. However, as he approached her, Rigg realized that his hopes to save her were in vain and fell down on his knees. Seconds later, the remaining SWAT officers entered the area and called for the forensics.

Shortly afterward, the crime scene was investigated by a forensic team joined by Detective Fisk. Thoroughly depressed, Rigg sat down and observed their work. He asked his partner, Lamanna, to cut down Kerry's mutilated corpse. Lamanna replied that he couldn't do this, but Rigg repeated his plea as he wanted to bestow at least some respect to her. He then left Lamanna alone when Hoffman approached him. Initially angry at him, Hoffman rebuked him for breaching through an unsecured door but calmed down when Rigg told him that he thought he could have saved Kerry. Depressed by Kerry's death, they talked about their work and how they could still go on. Hoffman then pointed at a message written on the wall, saying, "Cherish your life." Rigg asked him how they could if this was their life. Hoffman responded that they had chosen this life and told Rigg to go home.

Kerry's corpse

He was then informed by one of his colleagues that two FBI special agents wanted to talk to him. Moments later, he made acquaintance with Peter Strahm and Lindsey Perez. They told Hoffman about a key and a message supposedly sent to them by Kerry, thereby revealing that she had been their contact person. Upon examining the corpse, Fisk found a bullet shell clamped between the device and the body, which Hoffman ordered to be checked for fingerprints. When Agent Perez found the open padlock, she quickly concluded that this wasn't a real Jigsaw trap. However, when Hoffman said it was probably a trap built by Amanda Young, Agent Strahm negated this as Kerry weighed approximately 130 pounds. Amanda Young, on the other hand, weighed only 107 pounds according to her arrest report. Therefore, she couldn't have placed Kerry in the trap on her own, leading to the conclusion that a third, yet unknown, person assisted her and John Kramer. Kerry's corpse was then taken to the morgue, where Dr. Adam Heffner performed the autopsy on her body. (Saw IV, Saw VI)

After John Kramer's and Amanda Young's deaths at the hands of Jeff Denlon, another one of their victims, Kerry and her deceased colleagues - Daniel Rigg, Eric Matthews, David Tapp, and Steven Sing - were given a memorial. A picture of her stood next to those of her 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)


Allison Kerry was a hard-working detective who dedicated most of her life to her work. Therefore, she neglected any interpersonal relationships and eventually lost contact with her family. As she spent so much time at crime scenes and in other situations related to death, Kerry got to a point where she preferred the presence of a cold body over that of a living human being, causing her to become emotionally numb to a certain extent. She was also kind of selfish as she had an affair with her former partner, Eric Matthews, even though she probably knew he was married.

Kerry was eager to solve the Jigsaw case and was always anxious to be in control of the investigation. However, she was also capable of stronger feelings for other people. For six months, she blamed herself for Eric's abduction by Jigsaw as she was the one who had pushed him to help her. These feelings of guilt got worse over time, causing her to have nightmares in which she saw Eric. While she initially had a rather dominant personality, this changed after Eric's disappearance, indicating that she suffered from depression.


  • In Jigsaw, a newspaper article about the raid on Wilson Steel can be seen in the hidden closet in Eleanor Bonneville's studio. It includes a picture of Kerry and the SWAT, moments before entering the building.
  • Detective Allison Kerry was the first main character to die in an inescapable trap.
