She is murdered by The Joker at the end of "No Man's Land" arc (Detective Comics #741); the Joker had her catch an infant he was holding, and to prevent her leaking his location shot her in the head while her hands were full. Strangely, the Joker seemed to take no pleasure in this act, walking away with a sour frown as opposed to his usual maniacal grin before surrendering himself to the police. In retaliation, Gordon shot Joker in the leg. The Joker bawled over his wound and the fact that he would never walk again, until he "got the joke"; in Batman: The Killing Joke he had shot Gordon's daughter, Barbara, paralysing her, and now Gordon had done the same to him (though Joker suffered no paralysis as a result of the bullet).
