The Halloween Candy Killer | USA
It was a crisp Thursday evening on October 31st, 1974 — Halloween night — when 8-year-old Timothy O’Bryan returned home to Deer Park, Texas, clutching a pillowcase brimming with candy. The full moon hung low over the suburban streets, casting long shadows across carved pumpkins and leaf-strewn sidewalks. Kids in costumes still darted between porch lights, chasing the final thrills of the night.
Timothy had been trick-or-treating with his 5-year-old sister, Elizabeth, their father Ronald at their side, along with a neighbour and his children. It had been a night like so many others: laughter, sugar highs, and the comforting rituals of Halloween in small-town America.
When they returned home, Ronald allowed Timothy and Elizabeth to choose one piece of candy each before bed — a small, sweet reward to end the perfect evening. Timothy chose a Pixy Stix.
Moments later, he was gasping for breath, vomiting and convulsing.
By the time the ambulance arrived, it was already too late.
Timothy’s sudden and shocking death sent waves of panic through the community. Could a stranger have slipped poison into a child’s Halloween candy? Was this the nightmare parents had long feared – the urban legend made real?
But as investigators dug deeper, they uncovered something far more chilling. The truth about what happened that Halloween night wouldn’t just break hearts — it would shatter trust at the most fundamental level.
This is the story of Timothy O’Bryan… and the man who turned Halloween into a night of true terror.

The case:
In the 1970s, American children were raised on Halloween folklore. Every October, the same warnings circled playgrounds and kitchen tables: don’t eat unwrapped candy, beware of strangers, check for razor blades hidden in apples. Stories like these were usually brushed off as overprotective parenting or suburban legend — cautionary tales told to keep children close to home.
But on Halloween night in 1974, in Deer Park, Texas, one of those urban legends came horrifyingly true. And the truth behind it would prove to be far more disturbing than anyone could have imagined.
Ronald Clark O’Bryan lived in Deer Park with his wife, Daynene, and their two children — 8-year-old Timothy and 5-year-old Elizabeth. The family lived what appeared to be a normal suburban life. Ronald worked as an optician, while Daynene was a homemaker. They attended Calvary Baptist Church regularly, where Ronald sang in the choir and was seen as a devoted father.
But behind the scenes, things were far from stable.
Ronald was in serious financial trouble. He was more than $100,000 in debt — a considerable sum at the time — and behind on just about every financial obligation: mortgage, car payments, credit cards, personal loans. He was also facing disciplinary action at work and was in danger of losing his job. Friends and family were unaware of just how desperate things had become.
Meanwhile, Timothy — or Tim, as he was often called — was a happy, outgoing child. He loved Halloween and had been counting down the days. That year, he dressed in a Planet of the Apes costume — a popular choice at the time, thanks to the movie franchise. The costume came with a plastic mask and a vinyl jumpsuit, and Timothy was excited to wear it. His little sister, Elizabeth, dressed as a princess.
That Halloween evening, Ronald took Timothy and Elizabeth trick-or-treating in their neighbourhood. They were joined by their neighbours, Jim and Margie Bates, and the Bates’ children. The group visited several houses, collecting candy and enjoying the festive atmosphere. It was a crisp Thursday night, and a full moon illuminated the suburban streets — the kind of Halloween evening children remember forever.
At one point during their rounds, the group came to a house where the lights were off and no one appeared to be home. The children moved on to the next house, but Ronald stayed behind, saying he wanted to try knocking one more time. A few minutes later, he rejoined the group, now holding several 21-inch Pixy Stix — large plastic straws filled with flavoured powdered sugar.
Ronald claimed that someone had answered the door after the others walked away and handed him the candy sticks to give to the kids. He distributed the Pixy Stix to Timothy, Elizabeth, and three of the Bates children. Later that evening, they ran into another family Ronald knew from church, and he gave one more Pixy Stix to one of their children.
After the night’s festivities, the families returned home. Timothy and Elizabeth were eager to dive into their candy. As they were preparing for bed, Ronald told them they could each pick one piece of candy to enjoy before calling it a night. Almost immediately, Timothy said it tasted bitter and complained that his mouth was burning. He ran to the bathroom, began vomiting, and collapsed. Within minutes, he was convulsing.
Daynene called 911, and an ambulance arrived shortly, rushing him to the hospital, but it was too late. Timothy O’Bryan died en route, just past midnight — early on November 1st, 1974.
At the hospital, doctors immediately suspected poisoning, because of the smell emanating from the young boy. Emergency toxicology reports confirmed the presence of potassium cyanide in Timothy’s system — not just trace amounts, but enough to kill two or three fully grown adults. His cause of death was declared as acute cyanide poisoning.
News of Timothy’s death shocked the community and quickly spread beyond it. A child poisoned by Halloween candy — it was the stuff of nightmares, a terrifying confirmation of a myth many had dismissed. Panic spread among parents. Hospitals across Texas and beyond reported a spike in families requesting that their children’s Halloween candy be tested.
Investigators began their work by recovering the other Pixy Stix Ronald had handed out that night. All five remaining sticks contained similar quantities of cyanide. But by sheer luck, none of the other children had eaten theirs. Elizabeth had struggled to open hers and fallen asleep with it unopened. One of the Bates boys had been found the next morning sleeping with his Pixy Stix in his hand — the staple too difficult for him to remove. The others hadn’t gotten around to tasting theirs yet.
The potential tragedy that had been narrowly avoided was staggering. Had those children consumed the Pixy Stix, multiple lives could have been lost.
Initially, police considered the possibility that someone had tampered with candy and given it to Ronald unknowingly. But that theory soon fell apart.
Ronald told police that he’d received the Pixy Stix from a house on their trick-or-treat route, but when investigators traced his steps, they discovered that the house in question had been dark and unoccupied. The homeowner — who worked at a local airport — had been on shift the entire night and didn’t return home until after 11 PM. Several witnesses confirmed this, and the man had no candy in his home. He’d given out nothing that night.
This contradicted Ronald’s version of events. Investigators began to dig deeper into Ronald’s background — and what they found raised serious red flags. They learned that in the months leading up to Halloween, Ronald had taken out multiple life insurance policies on both of his children — without telling his wife. These included a $10,000 policy on each child, followed by additional policies totalling over $50,000 more. In total, Ronald stood to gain around $60,000 — the equivalent of more than $370,000 today — if one of his children died.
Further, in the days immediately following Timothy’s death, Ronald had called his insurance company multiple times, asking how soon he could collect on the policy. Investigators noted that Ronald seemed disturbingly eager to receive the payout — and far less focused on grieving the loss of his son.
Police then learned that Ronald had been asking colleagues and acquaintances in recent weeks about cyanide — where it could be bought, how much was lethal, and how it might be disguised. He had also attempted to purchase cyanide from a chemical supply company in Houston, though the transaction was never completed. While the exact source of the cyanide used in the Pixy Stix was never definitively identified, investigators concluded that Ronald had obtained it through deliberate planning.
As more evidence mounted, the image of Ronald O’Bryan as a caring father began to crumble. What emerged instead was a picture of a man under extreme financial pressure, desperate enough to kill his own child for a payout — and willing to risk the lives of several others to cover his tracks.
Investigators asked Timothy’s mother about his last moments. According to Daynene, he initially wanted to have a lollipop. But Ronald discouraged him from eating it, saying it would take too long to finish. Instead, he suggested the Pixy Stix. Timothy agreed, and Ronald helped him open it — the top was sealed with staples. The sugar inside had hardened and clumped, so Ronald assisted further, shaking the powder loose and helping Timothy pour it into his mouth.
This chilling account convinced investigators that Timothy had not chosen the poisoned candy by chance — he had been guided toward it. By his killer – his own father.
On November 5th, just five days after Timothy’s death, Ronald Clark O’Bryan was arrested and charged with one count of capital murder and four counts of attempted murder.
The arrest shocked the community. How could a father do such a thing — and on Halloween, no less? The media quickly dubbed him “The Man Who Killed Halloween.”
Timothy’s funeral was held at Forest Park Lawndale Cemetery in Houston. It was a private affair, attended by close family and friends. Ronald was present, but many noticed his behaviour was out of step with the somber occasion. He reportedly spoke casually about upcoming holiday plans and potential purchases — comments that those around him found jarring and inappropriate.
Witnesses would later describe Ronald as appearing detached, even self-satisfied. In the weeks following the funeral, some said he seemed to enjoy the attention the case brought him. That pattern would continue throughout his trial.
Ronald’s trial began in May 1975. The prosecution presented a meticulous case, relying on forensic evidence, eyewitness accounts, insurance records, and Ronald’s own actions in the days surrounding Timothy’s death.
Expert witnesses testified about the cyanide found in the Pixy Stix and the lethal quantities involved. Insurance investigators laid out the timeline of policy purchases and Ronald’s attempts to collect on them almost immediately after Timothy’s death. Chemical supply companies confirmed Ronald had inquired about purchasing cyanide before Halloween. Friends, co-workers, and church members testified about his odd comments, his financial struggles, and his increasingly erratic behaviour.
One of the most damning aspects of the case was how precise and premeditated the poisoning had been. The Pixy Stix had been carefully resealed with staples, suggesting deliberate tampering. And the fact that Ronald had passed them out to other children indicated a willingness to let multiple kids die if it helped obscure his true target — his own son.
Throughout the trial, Ronald maintained his innocence. His defence argued that someone else may have tampered with the candy and planted it without his knowledge. But they were unable to provide any credible alternative theory. There were no suspects, no motive for anyone else to target Timothy, and no plausible explanation for Ronald’s incriminating actions.
Observers at the trial noted that Ronald seemed to relish being at the centre of attention. He often smiled, made eye contact with reporters, and appeared more engaged by the spectacle than by the gravity of the charges he faced. To many, he didn’t appear like a grieving father — but a man who had finally found an audience.
After less than an hour of deliberation, the jury found Ronald Clark O’Bryan guilty on all counts. He was sentenced to death.
Ronald was sent to death row at the Texas State Penitentiary in Huntsville. There, the atmosphere was very different. As a child killer — especially one who had targeted his own son — Ronald was despised by other inmates. He was isolated for his own safety and known to correctional officers as manipulative, cold, and attention-seeking.
At first, Ronald leaned into his infamy. He referred to himself as “The Candy Man” and seemed to enjoy the notoriety. But over time, the reality of life on death row took its toll. Prisoners mocked and threatened him, and his isolation grew deeper.
Over the next decade, Ronald filed a number of appeals. All were denied. Courts upheld both his conviction and his sentence, finding the evidence overwhelming and his legal representation competent.
On March 31st, 1984 — almost ten years after Timothy’s murder — Ronald Clark O’Bryan was executed by lethal injection. He was 39 years old. In his final statement, he said:
“I forgive all – and I do mean all – those who have been involved in my death. God bless you all and may God’s best blessings be always yours.”
He never once admitted guilt.
Outside the prison, on the day of his execution, around 300 people had gathered. When word of Ronald’s death was announced at 12:48 AM, some in the crowd threw candy at anti-death penalty protesters, shouting “Trick or treat!”
Daynene, who had divorced Ronald and testified against him during the trial, did not attend the execution. Through her attorney, she issued a brief statement:
"October 31st, 1974, was a tragic night that changed our family forever. Tim, son and brother, was violently taken from us."
She later remarried and continued living in the Houston area. Elizabeth grew up away from the public eye.
The execution marked the end of the legal saga, but the story has never truly faded. Timothy O’Bryan’s murder remains one of the most shocking and chilling crimes in American history — not just because it happened on Halloween, but because it exposed something deeper: that sometimes, the most dangerous person in a child’s life is the one who’s supposed to protect them.
The case led to widespread changes in Halloween culture. Parents began inspecting every piece of candy. Hospitals introduced free X-ray services for Halloween night. Communities that once embraced the holiday with carefree joy became more cautious, more suspicious, more fearful.
But in all the years since, no case has ever matched the horror — or the betrayal — of what happened in Deer Park in 1974. There have been no confirmed cases of strangers randomly poisoning Halloween candy.
Timothy’s case stands alone.
He was a bright, curious boy who loved Halloween — a child who should have had a full life ahead of him. Instead, he became a symbol of one of the most callous and calculated crimes in living memory. Behind the glow of jack-o’-lanterns and the innocence of trick-or-treating, Timothy’s own father hid a deadly secret — a betrayal so vile it forever cast a shadow over Halloween night.
