- "Man, let's go! Let's go, Jack!"
- ―Jack Napier's partner[src]
Joe Chill mugged Thomas and Martha Wayne, tearing away her necklace. The Waynes were then shot and murdered by his partner, Jack Napier, although his reaction implied that he did not anticipate that Jack Napier would actually kill them. Then he began running away, to escape from the scene of the crime, urging Jack to follow him.
Behind the scenes
- Fans speculated that Chill may have been 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.
