The phone rings in Kim Byers’ kitchen. It’s 7.30am on May 10, 1994, and she’s making breakfast for the family before school – a regular busy Tuesday morning.
But today is not like other days.
Today, Kim’s father is calling to give her the news she’s been waiting 14 years to hear.
‘He’s gone,’ her dad says. ‘Gacy’s dead.’
Kim was just 16 when John Wayne Gacy lured her friend Rob Piest from the Illinois pharmacy where they both worked, before murdering him, then dumping him in the Des Plaines River.
Kim was the last person to see Rob alive and, aged just 17, was a key witness in the case against Gacy
She was the last person to see Rob, 15, alive, and the evidence Kim provided, as key witness at his trial, was enough to secure the death penalty.
The notorious serial killer spent 14 years on Death Row. When, finally, he was dead, it felt like the closing of a huge book.
Kim turned her back to the living room where her daughters were watching Sesame Street, and melted to the floor, sobbing quietly: ‘He’s gone.’
‘Why are you crying, Mommy?’ Little Courtney had wandered from her spot in front of the TV and crawled on to her lap, and was now dabbing at her mom’s tears.
Courtney Lund O’Neil remembers the moment clearly, as Kim repeated a lesson that was drilled into her for as long as she could remember: this world is not safe; danger lurks around every corner.
‘In life, always be careful,’ she told her daughter. ‘There are bad men out there. If a man pulls up in a van and offers you a ride or a popsicle or to see his puppies, you do not go. Never go. If he takes you anyway, you fight. You scream. You never give up. If he says he will kill your parents if you scream out, scream.’
Gacy raped, tortured, and killed at least 33 young men, burying many of them underneath his ranch-style house in Norwood Park township, near Chicago.

Kim’s proximity to the case – she had accidentally bumped up against Gacy in the pharmacy, looked into his dark eyes before he drove her friend to his death – changed her forever.
In her new book, Postmortem: What Survives the John Wayne Gacy Murders, Courtney says: ‘What haunts my mother will also come to haunt me.’
As she grew up, she was increasingly curious about her mom’s remarkable link to this case that made headlines around the world: the ‘Killer Clown’ who would regularly dress as ‘Pogo’ at local parties, and gained infamy for his sinister clown paintings.
So, when Courtney herself became a mother, Kim presented her with the diaries she wrote as a teenager and young woman.
‘I read it and was changed,’ she writes.
‘When I think about the mothers, I think about my own motherhood. All the unknowns, both beautiful and painful, I’m yet to hold… I wonder how any of the parents survived the experience of losing a son. I don’t know how anyone truly could.’
The day after Rob disappeared, Kim wrote in her diary: ‘He never came back to the store and he never went home. Rob would never run away, he had no reason to’
‘I can just imagine Rob lying out in some empty forest — alive but unable to move — crying for help with no one answering him’

December 12, 1978
‘Today was an absolutely miserable day. It started out good. I got up at 9.00 and took a bath. Then I got a phone call from a youth officer — he [Rob] never came back to the store and he never went home. Rob would never run away, he had no reason to. And this guy Gacy claims he never talked to Rob. I can’t believe Rob would have lied to us. But someone is obviously lying.
‘I held my cool for the whole day. But right before we were supposed to leave for the meet — I was talking to Mr Tanner (school counselor) and I just started crying. I feel so scared, worried and helpless. I can just imagine Rob lying out in some empty forest — alive but unable to move — crying for help with no one answering him. It is just not fair — Rob never did anything wrong to anyone.
‘I pray he has just run off somewhere and is at least safe! Kerry will call me and let me know any new news. I can’t talk about it anymore — my heart is being ripped apart. By the way we lost our meet.’
December 13, 1978
‘Well, no word about Rob yet. I feel worse and worse as time goes on. It’s the not knowing that’s ripping me apart. I called Ken [Rob’s brother] at 2.30. He said they have Gacy under surveillance. Tailed him and then lost him after 2 blocks — I could do better than that. I had a really morbid dream last night — (had it twice). We found Rob in a trunk of a beat-up old gold car. Any significance?????’
Early that morning, Gacy had reluctantly given a statement to the police. Unaware that Kim had seen him talking with Rob, he denied he’d had anything to do with him.
Strangely, he was covered in thick mud – which cops would eventually learn was a result of pushing his car out of sludge near the river after dumping Rob’s body.
Kim didn’t know any of this at the time, of course, but perhaps her dream did have some significance after all?
The next day, she went to school as usual, but was chilled to learn of her growing role in the case against the prime suspect. Cops had obtained a search warrant for Gacy’s house, and placed an officer outside the Byers’ home as protection.
‘If she witnessed what she said she witnessed, she could be in danger,’ writes Courtney. ‘Someone working with Gacy could potentially cause her harm. Come after her.’
December 14, 1978
‘Well, still no sign of Rob… I was still depressed. Cried twice… They (police) have a theory! I hope they find him soon. Also, they put the case up to the Grand Jury — he says I’m the key witness. I’m scared, say they come after me?!! Yuck.’
The moment cops entered Gacy’s house, the were hit with the smell of decay. They left that first search with no body, but with enough evidence to ensure Gacy remained in their sights.
‘Authorities found creepy oddities: the strange Tiki-style bar, the gallery wall of clown paintings, a hallway that looked like it was out of a haunted house, with bizarre yellow and brown zigzag lines on the walls, and then, a trap door that accessed a crawl space,’ writes Courtney.

‘Still no sign of Rob,’ Kim wrote in her diary. ‘I was still depressed. Cried twice… They (police) have a theory! I hope they find him soon’

As police searched below his house, they recovered the bodies of 29 boys and young men
‘They found startling mementos — a Maine West High School class ring; a 6mm pistol; handcuffs and keys; an identification card that was not Gacy’s. A film receipt.’
That film receipt was from Nisson Pharmacy, with the serial number 36119. Kim had put it in the pocket of Rob’s blue puffer jacket when she borrowed it on the day he went missing.
December 18, 1978
‘Mondays, yuck. Got up, took a shower, Mom took me to school. Was called into the office to speak with Mr Adams [the youth officer assigned to the case] and another detective. They found a pendant — I can’t remember if Rob had one on. I wish Rob would show up. I have a strange feeling something will happen tomorrow — call it women’s intuition — But first of all, the film stub I put in Rob’s coat pocket Monday is number 36119, the 19th (the film is not back yet) is tomorrow.’
December 19, 1978
‘Well, I guess my hunches were right. I came home after school to get something to eat before I went shopping, The phone rang. They asked me questions about the film slip. My guess is that they found it. Will pray for Rob.’
The receipt proved Rob was at Gacy’s house – and was enough to justify a second search warrant. With Gacy under arrest for weed possession, police descended on the property – focusing their attention on that eerie crawl space that smelled of death.
December 22, 1978
‘Mom came in and told me they found lots of bodies in Gacy’s house — and he is now leading them on a search for Rob’s… Gacy has confessed to 20 murders. They have not yet found Rob’s body. He said he dumped it into the Des Plaines River over the Kankakee Bridge — that’s far and wide. What sent them back for the 2nd search of the house was my film slip. They found it in Gacy’s garbage can — and did not realize that it came from Rob.’
Christmas came and went, but there was little to celebrate. By December 28, the body count had hit 21 at Gacy’s house, and there were still more places to search.
Rob was not recovered until the river started to unfreeze in the spring. As bluebells emerged from the hard ground along the bank of the Des Plaines River, a crane operator spotted a body floating by Dresden Lock.
April 9, 1979
‘They found Rob today — in Morris where the Des Plaines River meets the Illinois… Autopsy will be tomorrow (Tues). Dental something will be Thursday. Funeral is not planned yet but will be soon. Will stay home part of the day tomorrow. I need some time for myself.’
The following year, Gacy stood trial for the murder of 33 young men and boys. His youngest victims were 14, the eldest just 21.
As expected, Kim was a key witness. As she stood in the courtroom, willing the man who had cold-bloodedly raped and murdered her friend, to meet her eyes, Gacy refused to look up.
‘Kim thought he was a coward for not looking.’
On March 12, 1980, it took a jury less than two hours to find him guilty.
He was sentenced to death, but remained on Death Row for 14 years.
‘Just as an earthquake destroys a town or city or small country,’ writes Courtney, ‘murder has an epicenter, where and when the devastation took place, and its aftershocks reverberate.
‘With murder, the aftershocks don’t ever go away. Over the next decade, American media — tabloids, YouTubers, streaming services, sensational cable television, literature, film, documentaries — would aid in making Gacy a cult killer.
‘The victims’ stories surfaced rarely; those whose lives were forever altered by the murders; the mothers and fathers who mourned; the ones who loved the young men Gacy killed for his pleasure. For decades, these “other” stories became buried by the buzz and loudness of Gacy — still so very alive, even after his final breath.’
After multiple appeals, he was eventually executed by lethal injection early on May 10, 1994.
‘Gacy, now in his fifties, and no longer the thirtysomething-year-old murderer posing as an ambitious businessman, was set to be executed after midnight,’ writes Courtney.
‘In his final hours he didn’t seem worried; he still proclaimed his innocence; and he also talked about the Chicago Cubs to the guards. His last meal was fried shrimp, fried chicken, French fries, and strawberries.’
Outside demonstrators sang the song by Steam, Na Na Hey Hey Kiss Him Goodbye, while others chanted ‘Strap down the clown!’
‘Gacy was first injected with sodium thiopental, which put him to sleep,’ writes Courtney.
Some of Gacy’s victims. As of 2023, five or six of the young men he murdered are still unidentified
‘But an error occurred: a clog in the IV line delayed the second injection. Gacy lay there, about to enter the in between, while technicians prepared his execution.
‘About ten to 20 minutes later, the clog was cleared and the second drug, pancuronium bromide, entered Gacy’s bloodstream.
‘The third and final drug, potassium chloride, stopped the beating of Gacy’s heart. In the first hour of May 10, 1994, at 12.58am, the monster was dead.’
For Kim, her overwhelming sense was one of relief. ‘Finally, that guy is dead.’
But for other families, there would be no peace. At the time of his death, eight of Gacy’s victims remained unidentified.
As DNA technology advanced, authorities reopened the case and, on November 29, 2011, the first unknown victim was given a name: William George Bundy, a 19-year-old diver and gymnast.
‘Some victims are still unnamed,’ writes Courtney.
‘The most recent one identified was Francis Wayne Alexander in 2021. In 2023, according to the Cook County Sheriff’s Office, five remain unidentified, after being buried on June 12, 1981.
‘However, as of 2023, there is still current debate around Michael Marino’s identification as Victim No 14. According to his mother, still living, there was not a positive DNA match after his body was exhumed. So perhaps that number is six.
‘Either way, those mothers lived most of their lives without ever knowing what happened to their children.’
