Long before Dragnet, Gang Busters brought true crime to radio. Over its two decade run, the series presented stories of dangerous criminals and the determined police officers who brought them to justice. Producer Phillips H. Lord pulled cases from state and local law enforcement agencies and presented them in one of radio’s most down to earth crime dramas. Its memorable introduction - with the wail of sirens and a hail of bullets - gave rise to the expression “coming on like Gang Busters.” We’ll hear “The Case of the Incorrigible Killer,” first aired on ABC on October 9,  1948.
