— Jigsaw leads Rigg to the school[src]
Throughout the years of its existence, this school became the scene of investigations by the Metropolitan Police Department on several occasions. One of these incidents focused on Rex, a teacher working at the school, who became a suspect in a case of child abuse due to his daughter, Jane, who had received several injuries. To investigate the case, Officer Daniel Rigg and Detective Mark Hoffman were called to the school. While Hoffman interrogated Rex and his wife, Morgan, in the principal's office, Rigg talked to Jane and asked her about the bruises she had on her hand and her neck. Although he tried to convince her to tell him the truth about whether they were from an accident or from someone hurting her on purpose, Jane decided to remain silent.
Moments later, Hoffman and Morgan left the principal's office, and Jane asked Rigg if she could go home. Rigg told Hoffman not to trust Rex, as it was obvious to him that Jane didn't want to talk to them out of fear of her violent father. However, as Hoffman had no evidence against him, there was nothing he could do. Therefore, he told Jane to go back to her class. Rex, who felt safe now, clapped Rigg on the shoulder and sarcastically commented that "sometimes these kids just get out of control." This, however, provoked Rigg even further to the point that he attacked Rex and struck him in the face, breaking his nose and cheekbone in the process. Hoffman then had to pull him back and angrily told him to leave immediately. Following the incident, Rex tried to sue Rigg for the assault with the assistance of his lawyer, Art Blank. Hoffman, however, made an incorrect statutory declaration in order to protect his colleague. This eventually caused the charge to be dismissed, and Rigg's career wasn't further damaged or endangered by this incident. (Saw IV)
Years later, the school was chosen by John Kramer, better known as the Jigsaw Killer, as the location for one of his deadly games. The victim of this trap was Troy, a drug addict who had been sent to prison multiple times throughout his life. However, John was severely weakened and bedridden due to an inoperable brain tumor and therefore ordered his apprentice, Amanda Young, to set up the game to test Troy's will to survive. After abducting him, Amanda took Troy to a classroom at the school. She took most of his clothes off of him and sat him on a chair in the middle of the room. Then, she attached eleven chains to him by piercing the metal chain rings through several parts of his body. Ten of the chains pierced his hands, shoulders, Achilles tendons, arms and external obliques while the ring of the last chain was pierced through his lower jaw. Afterwards, Amanda cut a jigsaw piece from his skin and placed a TV and a nail bomb on a table right in front of him, before she left the room. However, as she started to doubt her and John's work, she decided not to give Troy any chance to survive and welded the door of the room shut.
Shortly afterwards, Troy woke up. Immediately frightened by the situation he was in, he jumped to his feet and started to scream in fear and agony when he saw the chains attached to him. Moments later, the TV in front of him suddenly turned on. On the screen appeared a frightening, mechanical ventriloquist puppet. The puppet greeted him and informed him about the situation. As he had been chosen for this test due to his repeated prison sentences, he should now get the chance to "break his chains" once and for all in order to survive and finally learn from his mistakes. When the TV turned off again, Troy noticed the nail bomb and immediately began to panic again. However, as he desperately wanted to survive, he eventually started to rip the chains out of his body. Despite his initial hesitation and the immense amount of pain, Troy managed to free himself from all the chains except for the one attached to his lower jaw. With only a few seconds left, Troy desperately tried to remove it but was eventually killed and ripped up by the explosion of the bomb.
Following Troy's death, a SWAT team led by Lieutenant Rigg arrived at the school shortly afterwards after a female caller had informed the police about the explosion. When they entered the building, they discovered that the door, which had been welded shut. Ultimately, they managed to break through a door by using a blowpipe. Upon entering and securing the room, they found the torn up remains of Troy. Rigg then ordered one of his men to call Detective Allison Kerry. Upon her arrival, she immediately feared that the victim was Detective Eric Matthews, her former partner who had been abducted by Jigsaw six months earlier. However her partner, Detective Hoffman, who was investigating the crime scene, told her it wasn't him. Hoffman also told her that the victim was held in place by eleven chains piercing his body and was eventually killed by a nail bomb. However she got suspicious when she learned that the SWAT team had to cut open the door as it had been welded shut, giving Troy no chance to escape even if he would've passed his test. This 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 video tape containing the instructions for Troy's trap was still intact despite the explosion. (Saw III)
Four days later, the school was again used for one of John Kramer's games. At this point, Art Blank, the lawyer of Rex, the abusive teacher and father of Jane, had become one of John's victims as well and was forced to wear a device which would cut his spine and kill him if he didn't follow the orders given to him. Therefore, he abducted Rex and Morgan, who had been violently abused by him over the years as well, and took them to a classroom not far from the one in which Troy had been killed. After that, he put a leather harness on them an chained them back to back to a metal column in the middle of the room. Then, Art used a dangerous device, which worked similar to a nailgun, and shot eight long, thin metal spikes through their bodies. While Morgan only received severe flesh wounds, Rex was mortally wounded as the spikes had pierced his major arteries. After that, Art chained a tape recorder to Morgan's wrist which contained the instructions for her test. Additionally, he positioned a chart of the human body in front of Morgan and a wooden chart with the words "Her life is in her hands" in front of Rex and also hung up numerous X-rays of the broken bones and injuries Morgan had received from Rex in the past. Having finished the preparations, Art went on and also set up a test for Officer Rigg, who was planned to arrive at the school shortly after Morgan's test. Therefore, he set up a timer, placed a second tape recorder for him on a table and placed a box with a photo of Tracy, Rigg's wife, behind the body chart. After that, he wrote the words "Save As I Save" on the blackboard and finally left the building.
Shortly afterwards, Morgan eventually woke up. Immediately frightened by the situation, she began to scream and played the tape attached to her wrist. This message, recorded by John Kramer, told her what she had to do in order to survive. If she wanted to live, she had to pull out the spikes from her body. However, this would inevitably kill her husband. Despite this, Morgan barely hesitated and began to pull out the spikes as soon as the tape ended. Rex, who had woken up by her screams, panicked and tried to prevent her from doing so. In the however, Morgan removed the spikes, causing Rex to succumb to his wounds. (Saw IV)
Not much later, Officer Rigg arrived at the building as expected, as he had to face a series of tests on his own in order to overcome his obsession with saving everyone around him. Therefore, John had left a clue at the Alexander Motel, the location of Rigg's previous test, to guide him to the school. While walking through the hallways, he came across the room where he and his men had found the remains of Troy four days earlier. Eventually, he reached a classroom with a red question mark painted on the door. Upon entering, he saw the words "Save As I Save" written on the blackboard. As he went further into the room, he found Rex and Morgan, still strapped metal column. When Rigg approached them, he thought that Morgan was dead like her husband, and was scared to death when she suddenly started to move and stare at him, claiming that she had won. When Rigg asked her what she had done, he realized what her task had been. He then tried to calm her down, before picking up the second tape lying on a table nearby, which told him about Morgan's test. While listening to the tape, Rigg took a look at the various X-rays hanging from the ceiling. The tape further told him that the key to his next destination was "just off the map."
After the tape ended, Rigg asked Morgan who put her in this situation and eventually pulled out the final spike from her shoulder. After doing so, Morgan thanked him for finally saving her. Moments later, Rigg realized that the map mentioned on the tape was a chart of the human body, which had been positioned in front of Morgan. Behind it, he found the photo of Tracy with the words "Go Home" written on its back. Frightened that she could have been in danger, Rigg asked Morgan if she knew where Tracy was. However, Morgan couldn't tell him anything useful. As she was freezing, Rigg covered Morgan with his jacket and handed her the second key that he had found earlier in his apartment, telling her that she had to safe herself. Morgan panicked and begged him not to leave her there alone, but before departing, Rigg set off the fire alert to make sure that Morgan would be found quickly. (Saw IV)
Due to the fire alert, the police was able to find Morgan in time to save her. After a brief interrogation, during which she identified Rigg as the one who saved her, she was taken to the hospital. After that, Special Agent Peter Strahm and Special Agent Lindsey Perez investigated the crime scene. Shortly after their arrival, Perez received a call and was informed about a connection between Morgan and Rex and the previous victims of Rigg's tests: all of them were clients of Art Blank, who had been able to defend all of them successfully in the past. Additionally, he was also the former lawyer and business partner of John Kramer as well as the lawyer of Jill Tuck, Kramer's ex-wife. However, only moments after she shared her new knowledge with Strahm, one of the forensic investigators accidentally activated the device used to pierce Morgan and Rex, which subsequently shot one last spike Perez' direction. Peter Strahm managed to pull her away but instead the spike pierced the head of a police photographer.
Following this incident, they left the room and discussed where they could possibly find the location where Rigg's game would end. Perez then informed Strahm that Jill Tuck was a co-proprietor of the school they were in, leading to the conclusion that there were still hints left for them to find. The agents separated to search the building and reunited shortly afterwards when they reached the principal's office. Upon entering the room, they discovered Jigsaw's ventriloquist puppet, sitting on a chair in a circle of candles with a tape recorder hanging from its neck. When Perez started the tape, it told her that her partner would soon take the life of an innocent man and warned her that her next move would be critical. However, instead of listening to the warning, Perez leaned forward to the puppet as it started whispering incomprehensibly. A few seconds later, the puppet's face suddenly exploded, severely injuring her face and neck with shrapnel. As Strahm was taking her to safety, the puppet mockingly laughed at her before it gave up the ghost. Strahm yelled for help, causing the police forces to call an ambulance, which arrived shortly afterwards. While lying on gurney, Perez handed him a key, which had been sent to them earlier, before she was finally taken to the Saint Eustace Hospital. Following this incident, Strahm left the school as well and returned to the police station. (Saw IV)
