CHICAGO — No human remains were found near the former home of serial killer John Wayne Gacy's mother on the Northwest Side, officials said Tuesday.
"Initial analysis indicates that there is no presence of human remains on the property," according to a statement from the sheriff's office.
Gacy was convicted of sexually assaulting and murdering 33 young men and boys in the 1970s and was executed in 1994. He buried 26 or his victims in the crawl space of his suburban Des Plaines home.
Officials believed remains of additional victims could have been buried in Norwood Park because of tips from former neighbors who said they saw Gacy performing "odd jobs in the middle of the night," said Frank Bilecki, sheriff's office spokesman.
Investigators used detector dogs that can smell human remains, ground-penetrating radar, and infrared techniques in an effort to find underground "anomalies," the statement said.
