In 1990, Officer Katherine Heller was at Lafayette Park when she was approached by a man who had been assaulted. After Heller radioed a description of the attacker, another Park Police officer, Scott Dahl, spotted a man matching the description and approached him. The alleged assailant began fighting with the officer and wrested the officers service pistol away from him. Heller approached and shot the man in the chest. Heller was named police officer of the year by Parade Magazine and the International Association of Chiefs of Police. She was the first U.S. Park Police officer, and the first female officer, to receive the IACP award.
