Arrest and Incarceration
John Wayne Gacy was arrested on December 21, 1978, after investigators linked him to multiple disappearances in the Chicago area. He was booked at Cook County Jail and held without bail pending trial.
Trial and Sentencing
In 1980, a jury convicted Gacy of 33 murders. He was sentenced to death and transferred to Stateville Correctional Center, where he spent years on Illinois death row while his appeals were processed.
Death Row and Execution
Gacy remained in custody at Stateville until his execution by lethal injection on May 10, 1994. His time in jail is documented in court records and official state prison archives.
