You were Peter Strahm's partner for 5 years, but you had to stop working with him because your superiors feared for your life. Before that, Peter shared his suspicions about Mark Hoffman and gave you evidence. When he disappeared, you began working with Eric and Mark. Since Peter was missing and suspected of being Jigsaw's partner, you were forced to remain silent.
When the recording of Seth's murder was found, the three of you were called to the girl who was removing noise from the recording. You all went there and waited for her to clean up the recording. Hoffman seemed distant. When the recording was cleaned, Mark, without hesitation, attacked Eric, instantly slitting his throat with the knife he carried in his pocket. The girl followed Eric's fate. Mark pushed you against the wall, grabbing your shoulder. His knife was near your stomach. He asked you if anyone else knew about this, to which you answered no.
"I know you're lying, bitch!"
He yelled at you, slamming you into the wall.
