Just like the Pighead from the previous game, Pighead II's real identity is never revealed, nor are his motives for working with Jigsaw. Sarah Blalok, who was a neighbor of David Tapp, revealed to Tapp's son Michael that she knew who the man behind the mask was and, whats more, that he was a friend of his father. But before she could reveal his identity, she was shot to death by Joseph Poltzer.
Mark Hoffman is the most likely suspect. In the game Pighead finishes off Police Chief Henry Jacobs by stabbing him repeatedly with a knife similar to how Mark did in Saw VI and, furthermore, in Saw 3D Mark is seen killing multiple cops with a knife. Also, case files in Saw II: Flesh & Blood from Detective Tapp sometimes state that he believed Hoffman would never become a bent cop unlike some of the others, suggesting Tapp had a respectable relationship with Hoffman. Pighead II is never hostile towards Michael but he does kill Jacobs and Solomon Bates.
- Despite all these theories, Pighead II's identity was never confirmed, his identity and his overall fate remain a mystery. However It is hinted that the identity of Pighead II is Mark Hoffman based on the Pighead's actions, such as using a knife to kill people who are aware of who he is.
