It was supposed to be a night of candy, costumes, and childhood joy. But on Halloween night in 1974, a father handed his son a treat that would become a national nightmare.
That treat was poisoned.
That father was Ronald Clark O’Bryan.
Known forever as The Candyman Killer, O’Bryan committed one of the most shocking and calculated murders in modern American history. His crime didn’t just take a life—it created an enduring cultural fear of Halloween itself.
This is the true story of Ronald O’Bryan, the suburban monster who weaponized candy, betrayed the trust of his child, and inspired decades of panic over poisoned Halloween treats.
Halloween Night, 1974: A Deadly Trick
On October 31, 1974, Ronald O’Bryan took his two children—Timothy (8) and Elizabeth (5)—trick-or-treating in Pasadena, Texas. They were joined by a neighbor and his kids. The night was cold and wet, but festive.
At one point, they approached a house with no lights on. The children ran ahead to the next house, but Ronald lingered behind. Minutes later, he caught up with the group, suddenly holding five giant Pixy Stix. He claimed a generous resident had handed them out.
He gave one to each of the kids and saved the fifth for another boy he knew.
That night, back at home, Timothy asked if he could have a treat before bed. Ronald said yes—and suggested the Pixy Stix.
Moments after taking a bite, Timothy clutched his stomach and began vomiting violently. He collapsed. Within an hour, he was dead.
The Investigation Begins
Initially, it looked like a tragic accident. But when police analyzed the Pixy Stix, the truth emerged: it had been laced with potassium cyanide—enough to kill three grown adults.
Investigators recovered the other four Pixy Stix before they were eaten. Each one had been opened, filled with poison, and resealed with staples.
This was not random. This was murder.
As the details emerged, suspicion quickly turned to the one person who had all the access, all the control, and all the motive: Ronald O’Bryan.
A Calculated Killer
Police soon uncovered that O’Bryan was drowning in debt. He had recently taken out life insurance policies on both of his children—without his wife’s knowledge. He owed thousands in loans and was about to lose his job.
The plan was horrific in its simplicity: kill his own son, collect the life insurance, and disguise the murder as a random Halloween tragedy.
To cover his tracks, he poisoned multiple candies and handed them out—to his daughter and other children—just to make it look random.
The level of premeditation was staggering.
The Trial and Execution
Ronald O’Bryan was arrested and charged with capital murder and attempted murder. The trial revealed more damning details:
- He had spoken to coworkers about cyanide months before the killing.
- He visited chemical supply stores trying to purchase it.
- He was reading books on poisons in the local library.
The jury deliberated for less than an hour.
He was found guilty and sentenced to death.
O’Bryan was executed by lethal injection on March 31, 1984, almost ten years after the murder. As he lay strapped to the gurney, a crowd outside cheered.
The Legacy of the Candyman Killer
Ronald O’Bryan’s crime had far-reaching consequences. Before 1974, fears of poisoned Halloween candy were rare and largely unfounded. But after Timothy’s death, panic took hold.
- Police departments across the U.S. began offering to X-ray Halloween candy.
- Schools warned students not to eat unwrapped or homemade treats.
- Parents began accompanying children door-to-door in greater numbers.
- Urban legends about razor blades in apples and needle-filled chocolate exploded.
And even though no other child has ever been confirmed to die from poisoned Halloween candy, the myth persists—because Ronald O’Bryan made it real.
A Killer Hiding in Plain Sight
O’Bryan wasn’t a stranger lurking in the shadows. He wasn’t a monster in a mask. He was a father. A man who tucked his children in at night. A man trusted by his church, his community, and his family.
That betrayal of trust is what makes this case so chilling.
It wasn’t a random act of violence.
It was premeditated filicide, wrapped in a holiday that symbolizes innocence.
Ronald O’Bryan forever changed the way Americans view Halloween. His crime wasn’t just a murder—it was a cultural rupture. He took a moment of joy and turned it into terror. He created a fear that still echoes in every cautious parent’s mind each October.
His story reminds us that not all monsters wear masks.
Some wear the face of a father.
