More about Devil in Disguise: John Wayne Gacy

The limited series kicks off with the case of Rob Piest, a missing Chicago area teenager. The investigation leads to the prime suspect who is revealed to be an affable and well-liked local businessman named John Wayne Gacy. As officers tail, interrogate and eventually arrest Gacy, it becomes clear to the Des Plaines Police Department that the young man is just one of many who have disappeared at his hands.

The series goes on to follow Lieutenant Joe Kozenczak and Detective Rafael Tovar as they lead the investigation that uncovers the remains of 32 young men and boys Gacy murdered, as well as the holes in the system that allowed Gacy to evade detection and capture for more than seven years.

In addition to unraveling Gacy’s crimes and early life, the series will also hit on the rivalry that ensued between Gacy’s lead defense lawyer, Sam Amirante, and the local prosecutor, William Kunkle, as the former tried to prevent Gacy’s execution while the families attempted to understand how and why their sons were taken from them.
