On Dec. 22, 1978, Gacy, realizing that his dark secrets were about to be

screams of his victims, he would stuff a sock or underwear into their

he raped them

bodies from Gacy's house.

James "Mojo" Mazzara, who still had his underwear lodged in his

a “Tim Lee” tattoo on his arm
1979 Finally in April 1979, the remains of Robert Piest were discovered in
the Illinois River.
Autopsy reports on Piest determined that he had suffocated from paper
towels being lodged down his throat. The family soon after filed a $85-
million suit against Gacy for murder and the Iowa Board of Parole, the
Department of Corrections and the Chicago Police Department for
Gacy's murder trial began:
Feb. 6, 1980 in the Cook County Criminal Courts Building in Chicago.
During the five-week trial the prosecution and the defense called more
than 100 witnesses to testify. The defense strategy was to establish that
Gacy was insane and out of control at the time of the killings. To
bolster this claim the defense put on the stand psychiatrists who had
interviewed Gacy prior to trial. The prosecution, on the other hand,
vigorously opposed the notion that Gacy was insane, contending that
his claim of multiple personalities was a death-penalty dodge.
On March 13, 1980, Gacy was sentenced to die. He was sent to Menard
Correctional Center in Illinois. He would remain there for just over 14
years until he was transported to the Statesville Penitentiary near Joliet
