After Harley Quinn fed his brother to the hyena, Bruce, he became one of the many individuals with a grievance against her. When she declared her emancipation from the Joker, he came after her, hoping to kill her. His quest, however, was not successful, as he was about to run over Harley with his van, Harley jumped out of the way and was accidentally shot in the head by Roman Sionis' chauffeur, who was himself flattened a moment later by Murray's out-of-control van.
