Seventeen years after John Wayne Gacy was executed for murdering up to 33 young men and 19 years after two prominent crime fighters publicly proclaimed their belief that he had likely killed more, present day Cook County officials are warming up to the possibility that Gacy did, in fact, murder others.
That wasn't the case nearly two decades ago when former Des Plaines Police detective and chief Joseph Kozenczak, who led the investigation that resulted in Gacy's arrest, and well-known FBI serial killer expert Robert Ressler publicly urged that a deeper investigation be launched to determine if there were more victims. No one at the time stepped forward and in some cases, Kozenczak and Ressler were ridiculed. Their belief that the mass murderer killed more was the subject of a front-page story in the Journal & Topics Newspapers on Apr. 29, 1992. No one at the time, however, took steps to discover if there were more victims. Now, however, Cook County Sheriff Tom Dart has reopened the Gacy investigation in hopes that DNA testing will help identify more possible victims. And now not only is Dart, but also others who were involved in the original Gacy investigation, reportedly expressing their belief that Gacy did kill more.
