The smell was the first thing they noticed. It wasn't just a "bad house" odor. It was a thick, heavy, sweet rot that seemed to cling to the detectives' clothes the moment they stepped inside the ranch house at 8213 West Summerdale Avenue.
Honestly, the neighbors in Norwood Park had been complaining about that stench for a long time. John Wayne Gacy usually had an answer ready, though. He’d blame it on a sewer backup or dampness in the crawl space. People believed him because, well, he was John Wayne Gacy. He was the guy who threw the massive summer block parties. He was the Democratic precinct captain. He was the man who owned PDM Contractors.
He was also the man with 29 bodies buried under his floorboards.
Why the Devil in Disguise John Wayne Gacy Narrative Persists
When people talk about Gacy today, they usually fixate on the clown. Pogo. The greasepaint. There’s something about a man dressing up as a children's entertainer while harboring a body count that feels uniquely Midwestern-gothic. But if you really look at the case, the clowning was barely a footnote in how he actually operated.
The "devil in disguise" wasn't a guy in a wig. It was the "Model Citizen" Gacy.
He was a master of the "magic trick." That’s what he called it when he’d convince a young man to put on a pair of handcuffs, showing them how easily he could slip out of them. Only, once the cuffs were on the victim, the trick changed. The "trick" became a nightmare of torture and strangulation.

The Robert Piest Disappearance
Everything unraveled because of a 15-year-old named Robert Piest. It’s kinda wild how one small mistake can bring down a monster who had been operating for nearly seven years. On December 11, 1978, Piest was working at Nisson Pharmacy. Gacy was there too, doing some contracting work. Piest told his mother he was going to talk to a man about a job that paid way better than the drugstore—$5 an hour, which was big money for a kid in the late 70s.
He never came back.
Des Plaines police Lt. Joe Kozenczak didn't let it go. When investigators searched Gacy's house, they found a photo receipt. It belonged to a friend of Piest. That was the thread. They pulled it, and the whole facade of the "successful businessman" came screaming down.
The Reality of the Crawl Space
If you’ve ever seen the photos of the recovery effort, they are haunting. It wasn't a basement. It was a crawl space—a cramped, dirt-floored area under the house.
Gacy actually had his own employees, young men who worked for PDM Contractors, dig trenches down there. He told them he was fixing plumbing or expansion issues. In reality, they were digging their own potential graves or the graves of their friends.

The recovery process was a slow, grueling nightmare for the forensic teams:
- They had to use hand tools because the space was too tight for machinery.
- Investigators wore masks to handle the overwhelming stench of decay and lime.
- Anthropologists were brought in because many of the remains had co-mingled over the years.
By the time they were done, they had pulled 26 bodies from that dirt. Three more were found elsewhere on the property. Four others, including Piest, had been dumped in the Des Plaines River because the crawl space was, quite literally, full.
The Victims Nobody Talked About
For a long time, the narrative was that Gacy only targeted "runaways" or "rough" kids. That’s factually wrong. Many of his victims were young men with families, jobs, and bright futures. People like Timothy McCoy, Gacy's first known murder in 1972. McCoy was just a 16-year-old kid on a layover at a bus station, trying to get home to Nebraska.
Gacy took advantage of the era. This was a time before the internet, before national missing persons databases, and before the "Stranger Danger" panic of the 1980s. If a teenage boy disappeared in 1975, the police often just assumed he’d "run off to California" to be a hippie. Gacy knew that. He fed on that systemic indifference.
The Psychological Mask
Experts like Dr. Richard Rappaport, who spent dozens of hours interviewing Gacy, often point to his extreme narcissism. Gacy didn't just kill; he enjoyed the "ultimate thrill" of power. He once told investigators that "death was the ultimate thrill," even claiming he had an orgasm during the act of murder.

He was diagnosed with Antisocial Personality Disorder (ASPD). He was a textbook psychopath—charming, manipulative, and completely devoid of empathy. He even tried to blame an alter-ego named "Jack" for the killings. It was a transparent attempt to dodge the death penalty by reason of insanity.
The jury didn't buy it.
The Botched End
Gacy spent 14 years on death row at Stateville Correctional Center. He spent his time painting—mostly those infamous, creepy clown portraits that still sell for thousands of dollars in "murderabilia" auctions. He never expressed a shred of real remorse.
His execution on May 10, 1994, was almost as messy as his life. A clog developed in the IV tube, turning what should have been a five-minute procedure into an 18-minute ordeal. His last words? A vulgar, two-word dismissal of the world.
What We Can Learn Today
The Gacy case changed how we handle missing persons in America. It led to better information sharing between departments and a more serious approach to teenage disappearances.
If you're looking into this case, don't just focus on the clown. Focus on the "mask of sanity." The most dangerous people aren't the ones hiding in the bushes; they're the ones hosting the neighborhood barbecue and shaking hands with the mayor.
Next Steps for True Crime Researchers:
- Check the Cook County Sheriff’s Office updates: As of 2024 and 2025, investigators are still using modern DNA technology to identify the remaining "Jane Does" (or in this case, John Does) from the Gacy property. There are still families waiting for closure.
- Review the Piest Case Evidence: Look into how a single pharmacy receipt can be the "smoking gun" in a serial killer investigation. It’s a masterclass in forensic persistence.
- Analyze the Systemic Failures: Study how Gacy’s prior conviction in Iowa for sodomy was effectively ignored when he moved to Illinois. Understanding these "red flag" failures is key to preventing future tragedies.
