— Bozwick's last words before getting abducted[src]

Detective Marv Bozwick, also known as Boz, is a fictional character from the Saw franchise, as well as a supporting character in Spiral.

He was portrayed by Daniel Petronijevic.


Early Life

Marv Bozwick was the husband of Kara Bozwick and father of Jamie Bozwick. He was also a homicide detective working for the Metropolitan Police Department. However, he was part of a large scheme to cover up corruption in the department. He took the witness stand many times and falsely testified, covered up and falsified evidence to put innocent people in jail and better serve his needs. Bozwick was very close friends with Ezekiel Banks, another member of the Metropolitan Police Department. He used to go to games with Ezekiel and even played with the latter's son.

Unlike most of the other cops, Bozwick remained in friendly terms with Ezekiel after he exposed the corruption in the department by revealing that Peter Dunleavy, a former member of the Police Department, killed a man named Charlie Emmerson for being willing to testify against a cop that murdered someone.

One night, a black SUV parked outside of their home. Kara told Marv about this, causing him to walk up and yell at the person inside of the SUV. (Spiral)

4th Of July Festival

Fifteen years later, William Emmerson, the son of Charlie, assumed the alias of William Schenk and decided to take the mantle of the Jigsaw Killer in order to murder corrupt cops and avenge his father. William decided that Bozwick would be his first victim and hired a small-time criminal named Benny Wrights to lure Bozwick into the sewers. Benny disguised himself of Uncle Sam and went in search of Bozwick.

During the night of 4th July, Bozwick was off duty. He was walking through the 4th of July Carnival and enjoying the festivities when suddenly, Benny collided with him. Bozwick became suspicious of this. Benny then stole the purse of a woman in the carnival. Benny ran away with the purse while the woman started to scream for help and asked someone to call the police, so Bozwick started to chase Benny while screaming to him to stop.

Making sure that Bozwick kept following him, Benny entered the sewers via the ladders of an underground tunnel and kept running away. Bozwick took of his gun and pointed it at the tunnel. Suddenly, a bunch of firecrackers threw by someone from the carnival exploded near Bozwick.


Bozwick decided to keep chasing Benny and went through the ladders of the underground tunnel until reaching the sewers. Suddenly, he heard a noise coming from another part of the sewers. He held his gun, lighted the way with his flashlight and ran to see what caused the noise. Bozwick went through another pathway and saw a mannequin dressed as Uncle Sam sitting on a chair in the distance. Believing it was Benny, he screamed at the mannequin to put his hands in the air. As he got no response, Bozwick kept slowly approaching to the mannequin and kicked it off the chair.

Boz is abducted by William

This made him realize it was just a mannequin and left him confused for a few seconds. Suddenly, William appeared behind Bozwick with a pig mask covering his face and wrapped a cloth, presumably laced with chloroform, around Marv's head until he went unconscious. After this, William took off Bozwick's shoes, coat and hat, and took his unconscious body to a subway station. He then stranded Bozwick on a wooden stepstool, tied his both hands to his back with barbed wire and attached his tongue to a metal contraption hanging from the ceiling by chains by piercing it with a screw.

Boz in his trap

Later, Bozwick woke up in the trap and panicked. Suddenly, a TV in the rails in front of him turned on and William appeared on the screen with the pig mask on his face and introduced Bozwick to his game. William told Bozwick that a train will be arriving to where he is in two minutes, and it was up to him if this will be his last stop. He then talked about how Bozwick took the witness stand many times and how he railroaded innocent people with his lies by putting them in the jail but today, he is the one who will end up railroaded. He told Bozwick that if he wants to escape, he has to tear from his mouth his tongue, which he used so many times to lie and deceive and that the best way of doing so was by doing a leap and using the weight of his body in order to tear it. Then, the TV turned off and the game began.

Boz right before he is hit and killed by the subway

Bozwick struggled a bit until he was able to untie his hands from the barbed wire. After that, he grabbed the metal contraption and vainly tried to pull it off in an attempt of get it off of his tongue. Bozwick started to cry out of pain. Meanwhile, the train was getting closer to Bozwick, with the conductor too distracted to notice him. After noticing the train, Bozwick got desperate and continued struggling to get the metal contraption off of his tongue, but once the train got closer enough to him, Bozwick startled and accidentally jumped off the stepstool, causing his tongue to be teared out by the contraption. However, right when he was falling to the ground, Bozwick got run over by the train, tearing him to pieces. The conductor stopped the train and observed the remains of Bozwick that were splattered in the train's window in horror, as he just realized what happened. (Spiral)


Zeke and William at the crime scene

When the game ended, William returned to the subway and removed the metal contraption along with Bozwick's tongue. He then put Bozwick's tongue and police plaque (which had the numbers 4-5-3) inside a small box, tied the box with a string and left it on the metal bars of one of the windows of a courthouse building. He also painted a red spiral on the wall and recorded a video which he would later send to Detective Ezekiel Banks in order to tell him about how each officer of the department will be tested and also give him a clue about who was the first victim of the game.

The crime scene got later reported to the Metropolitan Police Department, believing that it was a homeless man was the one who got run over. Once Ezekiel Banks and William Schenk arrived at the subway where the game was played, they found various police officers taking evidence. Zeke asked the police officer that was securing the scene what happened, to which the officer told him to see it for himself. Zeke and William passed the security tape and observed the remains of Bozwick while William pretended to be disgusted and wanting to vomit. Ezekiel told William that if he wants to vomit to not do it in the evidence, to which William replied that he will not, as he's been waiting to do this since he was twelve years old. While Ezekiel was lighting the remains of Bozwick with his flashback, William saw the TV, which was destroyed when the train arrived and asked if TV sets are in subways, to which Zeke replied telling him that lots of things appear in subways. William then said that it will be difficult to identify Bozwick, who was still believed to be a homeless man, but Zeke wasn't sure of the victim being a homeless man, due to noticing a step counter watch in one of Bozwick's arms. He was also able to identify that Bozwick was married and was wearing a Fitbit.

Zeke and William find the box

At the police 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 a 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 Deborah Kraus, arrived at the scene too. William asked what they were doing there to which Fitch replied saying 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.
