The clock ticked past midnight on May 10, 1994, as the man who had terrorized Chicago for years took his final, rasping breaths inside the sterile execution chamber at Stateville Correctional Center. John Wayne Gacy, the serial killer who had tortured and murdered at least 33 young men and boys, was pronounced dead at 12:58 a. m.
, ending a 14-year wait for justice that had consumed the families of his victims and the nation’s collective conscience. But in his final 24 hours, Gacy offered no remorse, no apology, only a chilling defiance that underscored the depth of his depravity.
It began quietly. At 6:30 a. m.
on May 9, 1994, Gacy awoke in his solitary confinement cell, fully aware that this would be his last dawn. He had spent nearly a decade and a half in near-total isolation, his only companions the brushes and paints he used to create eerie clown portraits. Now, even those were set aside.
The routine of the day carried a heavier weight. Prison staff served a simple breakfast of eggs, toast, and coffee. Gacy remained disturbingly calm, showing none of the fear or remorse that might have been expected from a man facing state-imposed death.
Throughout his years on death row, Gacy had maintained his innocence, casting himself as a victim of a corrupt justice system. He had been convicted in 1980 for the torture murders of 33 young men and boys, many of whom were buried in the crawl space of his Chicago-area home. But as the hours dwindled, even Gacy must have known the curtain was about to fall on his twisted performance.
By 9 a. m. , he began receiving visitors.
His mother had died years earlier, and most of his family had severed ties, unable to reconcile with his monstrous acts. Except for one person: his younger sister, Karen Gacy Kuzma.
Despite everything, Karen stood by her brother in those final hours, unable to let go of the bond they had shared since childhood. A chilling photograph from that day shows them hugging and smiling, as if the looming execution and the weight of his crimes did not exist. Her loyalty was not about approval but a deep sibling connection she could not abandon.
As the morning wore on, his legal team and spiritual advisers joined them, working frantically on last-minute appeals. But the chances of a reprieve were slim, and everyone, including Gacy, knew it.
Even in those final hours, Gacy clung to his innocence, spinning tales of conspiracy and injustice, insisting he had been framed. Karen sat nearby, watching the brother she had once known vanish behind the monstrous persona he had become. There was no sign of remorse, no acknowledgment of the lives he had destroyed, only the cold, detached demeanor that defined the psychopathic mind behind his crimes.
By the early afternoon, around 2 p. m. , a Catholic priest arrived to administer the last rites.
Gacy, who had converted to Catholicism while on death row, had requested this final act of spiritual comfort. It marked a sobering end to a life defined by darkness.
As evening approached, tension gripped the prison. Outside, a crowd had gathered, some protesting the death penalty, others eagerly awaiting justice. The atmosphere was thick with anticipation, the walls of the prison seemingly bracing for what was to come.
Inside, prison staff began the final preparations for the execution. Gacy was moved to a holding cell located just steps away from the execution chamber. Guards watched his every move with heightened vigilance to prevent any last-minute attempts at escape or self-harm.
The atmosphere in the facility was charged with an oppressive weight as everyone present was acutely aware of what was about to happen.
At around 7 p. m. , Gacy was given his final meal.
The request revealed a chilling normalcy: a bucket of Kentucky Fried Chicken, a dozen fried shrimp, french fries, fresh strawberries, and a Diet Coke. This meal was a dark nod to his past as a manager of three KFC restaurants, a twisted reminder of the facade he had maintained. After his meal, Gacy was allowed to shower and change into a simple prison uniform.
He declined the offer to make a final phone call and spent his remaining time talking with his spiritual adviser and legal team, his thoughts still fixated on his case and the injustice he believed had been done to him. The guards watched closely, but Gacy remained calm, detached, and utterly unrepentant.
At around 11:30 p. m. , the fateful moment arrived.
John Wayne Gacy was escorted from his holding cell to the execution chamber. Though the distance was short, each step carried an overwhelming sense of finality. Flanked by a group of stern-faced prison guards, Gacy moved with a steady gait.
A chaplain accompanied him, offering spiritual comfort in these last moments. Inside the execution chamber, Gacy was strapped to a gurney for the lethal injection. The room was sterile and clinical, designed to end lives with as little 𝒹𝓇𝒶𝓂𝒶 as possible.
Behind a glass partition, a small group of witnesses gathered: media representatives, victims’ family members, and law enforcement officials.
When the moment came for Gacy to make a final statement, the room fell into an expectant silence. All eyes were on him, waiting for perhaps a hint of remorse, an acknowledgment of the countless lives he had destroyed. Instead, Gacy met the moment with a cold and defiant sneer.
His lips curled into a smirk as he uttered the words, “Kiss my ass.” It was a final act of rebellion from a man who had spent his life manipulating and terrorizing others. There was no apology, no reflection on the horrors he had inflicted, only a chilling dismissal of the gravity of the situation.
At 12:01 a. m. on May 10, the lethal injection process began.
The execution used a three-𝒹𝓇𝓊𝑔 cocktail meant to bring a swift end: an anesthetic to induce unconsciousness, a paralytic agent to stop breathing, and potassium chloride to stop the heart. But in a grim twist, the execution did not proceed smoothly. The intravenous lines became clogged, causing an agonizing delay.
For 18 long minutes, Gacy lay on the gurney, silent and expressionless, as technicians worked frantically to fix the issue. The tension in the room was unbearable. Eventually, the procedure was completed, and at 12:58 a.
m. , John Wayne Gacy was pronounced dead.
By 3 a. m. that night, Gacy’s body was taken to the Illinois Department of Corrections Medical Center for an autopsy, as required by law.
The autopsy confirmed the cause of death as lethal injection, with meticulous details documented. Scientists removed Gacy’s brain in hopes of uncovering explanations for his crimes, but no significant abnormalities were discovered. Three days later, Gacy’s remains were cremated, and his ashes were returned to his family.
Unlike other infamous criminals whose graves become sites of morbid fascination, Gacy’s final resting place remains private. There would be no memorial, no marker, just the ashes of a man who had caused so much pain.
The execution of John Wayne Gacy closed one of the darkest chapters in American criminal history. For the families of his victims, some of whom witnessed his final moments, there was a sense of relief that justice had been served. Yet the pain and trauma caused by Gacy’s actions will never fully fade.
His final 24 hours were a haunting blend of routine and tension, a grim countdown to a life steeped in horror. From his last meal to his chilling final words, each moment reflected the monstrous man who had terrorized so many. Even in death, Gacy remained a figure of defiance, a man who had taken many lives and given nothing back.
His final hours were a testament to the monstrous nature of his life, a life that ended as it had been lived, without redemption or regret. Gacy’s legacy is dark and complex, marked by his status as one of history’s most notorious serial killers. His case continues to captivate criminologists, psychologists, and true crime enthusiasts alike.
But for the families of the 33 young men and boys he murdered, there is only the hollow echo of a final insult: “Kiss my ass.”
