Joe Chill (Clyde Gatell)

"Man, let's go! Let's go, Jack!"

- Jack Napier's partner

This man mugged Thomas and Martha Wayne, who were then shot and murdered by his partner, Jack Napier. He grabbed Martha's necklace and was in a brief struggle with Thomas until his partner shot him, and the necklace was broken. Then he was last seen running away, perhaps because he may have heard a police siren or rapidly approaching footsteps.

Behind the scenes

 * It is possible that the partner is Joe Chill. The fact that he's the one who actually tried to mug them makes it highly likely.
 * Other fans have speculated that this man may be Robert Hawkins or "Bob the Goon", who was always close to Napier and seemed to have a long history with him. Considering his loyalty to Napier even after he was disfigured and reinvented as the psychotic Joker, Bob's chances of being this man only increase but the chances of being Chill increase too for trying to be faithful to the original comic.
