There’s a reason John Wayne Gacy’s name still stops people in their tracks, decades after his crimes came to light. He shows up again and again in documentaries, podcasts. Now a new scripted Peacock drama, Devil in Disguise: John Wayne Gacy. Which has quietly introduced his story to a whole generation of viewers who weren’t even alive when it happened. Between 1972 and 1978, a contractor who moonlighted as a children’s party clown murdered at least 33 young men and boys – and buried most of them under his own house.
His execution in 1994 didn’t really end things. Between the original murders, years of appeals, a 2021 documentary. Now a 2025 dramatization, a lot of information floats around – and people easily mix up the different projects. Here’s what actually happened: who Gacy was, how his trial went. how he died, and what to know about the Devil in Disguise cast and episodes.

Who Is John Wayne Gacy?
He was born in Chicago on March 17, 1942, and by 1980 he’d been convicted of killing 33 young men. Teenage boys in Norwood Park Township, a suburb just outside the city. But that’s only half the story, because almost nobody around him saw it coming. Gacy ran a construction business, dabbled in local Democratic politics, and once got his photo taken with First Lady Rosalynn Carter through volunteer work. He looked, by every outward measure, like a guy who had his life together.
That’s actually the whole reason people are still talking about this case. Neighbors describe him as the friendly, hardworking type – the guy throwing block parties, showing up to help with community events. And underneath all of that. According to what prosecutors proved in court, was someone who lured teenagers and young men into his home with fake job offers, alcohol, or a magic trick or two, then assaulted, tortured, and killed them.
John Wayne Gacy Crimes: How the “Killer Clown” Operated
Gacy wasn’t a first-time offender when the Chicago murders started. He’d already served time in Iowa in the late 1960s for sexually assaulting a teenage boy. After getting out, he moved back to Illinois, remarried, and started PDM Contractors – the same company that would go on to employ a few of the men he’d later kill.
The clown thing is where a lot of people first hear about him. He performed at kids’ hospitals, parades, and birthday parties under the names “Pogo the Clown” and, later, “Patches the Clown,” and that image has basically become shorthand for the case ever since – proof of how completely he hid behind a friendly, harmless persona. For what it’s worth, investigators never found any real connection between the clown act and how he actually picked or approached his victims. It was just one more layer of the normal, trustworthy guy he wanted people to see.
Over those six years, he killed at least 33 young men and teenage boys, most of them pulled in under the pretense of work, a drink, or just hanging out. He’d restrain and sexually assault them, strangle most of them to death, then bury the bodies in a crawl space under his house. Once that ran out of room, he started dumping remains in the nearby Des Plaines River instead.
How Many People Did John Wayne Gacy Kill?
The confirmed number is 33 – 29 recovered from the crawl space and grounds of his Norwood Park property, and four more pulled from the Des Plaines River after he ran out of space to bury anyone else at home. When he was convicted on all 33 counts in March 1980, it made him, at that point, the most prolific serial killer confirmed in U.S. history.
Naming all the victims took decades. Investigators started with dental records, then leaned on DNA technology as it improved, but several of the young men still went unidentified for years after Gacy was executed. Even now, a handful remain unnamed, and Cook County keeps coming back to the case periodically with newer genetic genealogy tools.
A rundown of how investigators worked to identify the victims:
- Dental records, used in the earliest identifications
- DNA testing, later expanded into genetic genealogy work
- Personal belongings pulled from the crawl space
- Missing-persons reports families had filed years before
- Records kept by the Cook County Medical Examiner’s office
- Continued efforts to name the handful of victims still unidentified
John Wayne Gacy House: Inside 8213 Summerdale
The house was at 8213 West Summerdale Avenue, in an unincorporated part of Norwood Park Township near O’Hare Airport. Nothing about it stood out – just a plain, single-story brick ranch – which is part of why what was found underneath it hit the neighborhood so hard.
Gacy used part of the place as an office for his contracting business and reportedly let a few employees crash there sometimes. But the crawl space beneath the house, about 40 feet wide, is where most of the victims ended up buried. When police started digging in December 1978, the scale of what they pulled out – along with the smell investigators described at the scene – became one of the case’s most lasting, horrifying images.
All that digging left the house structurally unstable, and Cook County eventually had it torn down. That happened on April 11, 1979, after Gacy’s lawyers lost an appeal to the Illinois Supreme Court trying to stop the demolition. The empty lot reportedly drew curious visitors and ghost hunters for years before a new three-bedroom house went up there in 1986. It now carries a different address, 8215 West Summerdale Avenue, and has changed hands a few times since.
John Gacy Arrest, Trial, and Conviction
The case cracked open after 15-year-old Robert Piest went missing in December 1978. He’d last been seen heading off to talk to a contractor about a job – a contractor police quickly traced back to Gacy. Once they searched his house, they found belongings connected to several other missing young men, and within days investigators were already pulling remains out of the crawl space.
Here’s how it all played out, step by step:
- 1968 – Convicted of sodomy in Iowa; walks free after serving part of an 18-month term
- 1972–1978 – Kills at least 33 young men and teenage boys across the Chicago area
- Dec. 11, 1978 – Robert Piest goes missing, reportedly on his way to meet Gacy about a job
- Dec. 21, 1978 – Police arrest Gacy and start searching his property
- Dec. 22, 1978 – The first remains turn up in the crawl space
- March 13, 1980 – Found guilty on all 33 counts and sentenced to death
At trial, his defense tried the insanity route, arguing a psychiatric condition should’ve kept him from being found guilty. The jury didn’t buy it. He was convicted on every single count – sentenced to death for 12 of the murders, and natural life in prison for the other 21.
John Wayne Gacy Death: Execution and Final Hours
People still search for how Gacy died more than three decades later. After 14 years of appeals from death row at Menard Correctional Center, he was transferred to Stateville Correctional Center in Crest Hill, Illinois, and executed by lethal injection in the early hours of May 10, 1994. He was 52.
The execution itself didn’t go smoothly – a clogged IV line reportedly held things up by ten to twenty minutes after the first sedative had already been given. Gacy was pronounced dead at 12:58 a.m. Outside the prison, crowds had gathered, split between people protesting the death penalty and people who’d simply come to see it happen.
A note on “John Wayne Gacy last words” searches: what he actually said, if he said anything at all, is still disputed – even among the people who were there. The version most people repeat is a dismissive “Kiss my a–,” though some accounts call that an urban legend. Illinois’ state corrections director at the time said Gacy’s real last statement accused the state of “murdering him,” not any acknowledgment of what he’d done, while at least one prosecutor who witnessed the execution insists Gacy didn’t say anything at all. Treat this one as unresolved rather than fact.
Where Is John Wayne Gacy Buried?
This is genuinely one of the murkier details in the case. Some local reporters and cemetery researchers have pointed to Mary Hill Catholic Cemetery in Niles, Illinois – where Gacy’s parents are buried – as a likely spot, on the assumption he’d have been laid to rest with family. But people who’ve tried to confirm a gravesite there say cemetery staff have turned them away, and there’s no public record that nails down where his remains actually are. Compare that to his victims, several of whom have clearly documented burial sites at Queen of Heaven Cemetery in Hillside, Illinois – the contrast says a lot. Treat the burial question as unconfirmed.
Devil in Disguise: John Wayne Gacy – The Peacock Series
All the renewed attention traces back to Devil in Disguise: John Wayne Gacy, an eight-episode scripted limited series that dropped on Peacock on October 16, 2025. It’s essentially a dramatized companion piece to Peacock’s earlier 2021 docuseries on the same case, created by Patrick Macmanus – the same guy behind Dr. Death and The Girl from Plainville.
Instead of telling the story from Gacy’s point of view, the show focuses on the investigation, and more specifically on the victims and their families – a deliberate choice, according to producers, meant to move away from the usual “killer’s-eye-view” format that true-crime dramas tend to fall back on.

Devil in Disguise: John Wayne Gacy Episodes
Peacock dropped the whole season at once instead of doing weekly releases – all eight episodes were available from day one. It opens with “Ten Days,” which covers a teenager’s disappearance and the early days of the investigation, followed by episode two, “Johnny.”
A few basics on the show, at a glance:
- Episodes: 8, total
- Premiered: October 16, 2025
- How it dropped: All at once, not weekly
- What it is: A scripted true-crime drama
- Behind it: Noah Oppenheim, Sarah Bremner, and Liz Cole executive produce for NBC News Studios, among others
Documentary Where to Watch: Peacock
Peacock is the only place streaming the 2025 series – you’ll need a subscription to watch it. One thing worth flagging: Peacock actually hosts two Gacy projects with almost identical names, the 2021 documentary John Wayne Gacy: Devil in Disguise and the 2025 scripted drama Devil in Disguise: John Wayne Gacy, which is exactly why search results for the two keep getting crossed.
A note on “John Wayne Gacy Netflix” searches: this one trips people up constantly. Neither Peacock project – not the scripted series, not the 2021 docuseries – is on Netflix at all. What people are usually thinking of is a completely separate title, Conversations with a Killer: The John Wayne Gacy Tapes, a Netflix documentary built from archival prison interview recordings with Gacy himself. There’s no reporting anywhere that puts the 2025 Devil in Disguise series on Netflix.
John Wayne Gacy Documentary vs. Movie vs. Show: Sorting Out the Titles
With this many projects sharing his name, it helps to lay them out clearly:
- John Wayne Gacy: Devil in Disguise (2021) – Peacock’s original documentary, pieced together from archival footage and interviews.
- Devil in Disguise: John Wayne Gacy (2025) – the eight-part scripted retelling on Peacock, with Michael Chernus in the lead.
- Conversations with a Killer: The John Wayne Gacy Tapes – Netflix’s take, built entirely around recorded prison interviews with Gacy.
- To Catch a Killer and Gacy – older theatrical and TV dramatizations from decades before Peacock’s series.
Given how similar the titles are, it’s easy to click the wrong link. If you specifically want the 2025 dramatized version with Michael Chernus, Peacock’s where to go – not Netflix, and not some standalone movie.
Why the Gacy Case Still Draws Attention
More than 30 years after his execution, people are still drawn to this case for what it says about how someone who looked completely ordinary – likable, even – could hide something this extreme for so long. It also raises harder questions about the system around him: families whose reports went nowhere, police follow-up that fell short, all of it letting the killings continue for years. The 2025 series leans into that directly, treating the show less like a portrait of a killer and more like an account of everything that failed his victims along the way.
That’s probably why interest in both the show and the case in general hasn’t really faded, even though the crimes themselves were resolved with his execution back in 1994. Between the two Peacock shows, the unrelated Netflix interview series, and decades of earlier books and films, Gacy’s story has turned into its own small corner of true crime – one that keeps finding new audiences every time someone adapts it again.
