Joseph was a corrupt vice cop who abused his position to steal drugs seized from criminals and sell them in a cartel, alongside Henry Jacobs, Carla Song, and Sarah Blalok. As a member of the group, he was kidnapped by Jigsaw and placed in a vice trap designed to crush all of his limbs and his skull unless Michael could save him. Michael's father had accidentally uncovered their drug cartel while investigating Jigsaw, so he teamed-up with the Henry Jacobs to hunt and kill Michael, Carla, and Sarah to tie up any loose ends that could reveal their criminal actions. He later executes Sarah as she is about to reveal the true identity of Pighead II. He and Michael get embroiled in a fight which results in them breaking through a wall and plummeting into an alley below. They struggle over Joseph's gun, but Michael eventually triumphs and fatally shoots Joseph in the head.
