The mother had only turned her back for a moment. Judy Poulton was inside her apartment in Rochester, New York, finishing the last of her magazine leaflets on the evening of May 23, 1994. Her four-year-old daughter, Kayanne, had begged to go outside and ride her tricycle.
It was a warm, sunny evening, and the yard was filled with other children. Judy agreed, telling Kaye to stay close. She planned to finish her work, load the magazines into the car, and then take her daughter to McDonald’s.
But when Judy stepped outside just minutes later, the tricycle was gone. The yard was silent. Kaye was nowhere to be found.
Judy called out her daughter’s name, her voice rising with panic. She walked the perimeter of the complex, then began searching the grounds. The distinctive creak of Kaye’s tricycle wheels was absent.
Neighbors joined the search, fanning out across the apartment complex. The property was bordered by a fence and a nearby highway, but Judy was certain her daughter could not have wandered far on her own. Kaye had never disobeyed her mother before.
Fear gripped Judy’s heart as she dialed 911.
Police arrived within minutes. They were joined by firefighters and canine units. Officers went door to door through the complex’s 300 units.
The prevailing theory was that if this was an abduction, the perpetrator was likely a resident. An outsider would have been noticed. Residents willingly let police inside.
When no one was home, the complex manager used spare keys. But the search yielded nothing. Kaye and her tricycle had vanished.
By 4 a. m. , the case was reclassified as a kidnapping.
A special unit took over.
Detectives questioned Judy about anyone who might wish them harm. She immediately mentioned a 22-year-old neighbor named Mark Christie. Mark had recently moved into the complex with his wife and young son.
Judy recalled unsettling interactions. Mark had told her that Kaye was very beautiful, but the tone had made her uncomfortable. He had added that he had been watching all the little girls in the complex and that Kaye was the prettiest.
Then came an even more alarming question: Mark asked if Kaye would tell her mother if someone tried to touch her. Judy had ended the conversation and kept her daughter away from him.
On the night of the disappearance, Judy had seen Mark in the yard with his son shortly after she began searching. She asked if he had seen Kaye. He said no.
She noticed something odd: his sneakers were missing their shoelaces. But at the time, she was too frantic to dwell on it. Detectives brought Mark in for questioning.
He denied any involvement and agreed to take a polygraph test. The operator detected no deception. Mark also had an alibi: Judy herself had seen him in the playground.
Police searched his apartment early in the investigation but found nothing. Mark was released.
The case went cold. Months turned into years. Judy never stopped searching.
She quit her job and dedicated herself to finding her daughter. She printed and posted flyers, contacted media outlets, and raised $100,000 in reward money. She appeared on the Oprah Winfrey Show and on a popular crime program.
She persuaded local businesses and even two airlines to include flyers with tickets. The police received over a thousand tips, but each led to a dead end. For two long years, the fate of Kayanne Poulton remained a mystery.
Then, on August 9, 1996, a woman called the police. She was in shock. She told officers that she had been arguing with her husband, Mark Christie.
During the argument, Mark had confessed to killing Kaye Poulton. The woman immediately took her child and went to her father’s house before calling 911. Detectives were stunned.
But they faced a serious legal obstacle: under New York state law, communications between spouses are privileged. Mark’s confession to his wife could not be used in court. Without that confession, the police had no admissible evidence.
Detective Crow, who had worked the original case, decided to approach Mark anyway. He learned that Mark and his family had moved out of the complex shortly after Kaye’s disappearance. The reason: two sets of parents had reported Mark for standing naked in his doorway.
No charges were filed because he was in his own home, but the behavior was deeply suspicious. Crow drove 50 miles to Mark’s new city. Mark’s mother answered the door and said her son would not speak without a lawyer.
But Crow managed to convince Mark to talk over coffee.
At a restaurant, Crow used a careful, friendly approach. He played on Mark’s ego, suggesting that Mark had outsmarted the police. Mark began to boast.
He revealed that Kaye’s tricycle had been in his apartment for three days after her disappearance. He had cut it into pieces and hidden them in places too small for a child, then gradually disposed of them. Police had been checking cars leaving the complex, but they were only looking for a missing girl, not small bags.
Mark had beaten the system.
Crow continued to coax. He suggested that perhaps Kaye’s death was an accident. Mark asked about possible sentences.
Crow mentioned 25 years. Mark complained that would be unfair, that he had already lived in a personal hell for two years. Crow then appealed to his conscience, saying Kaye’s parents deserved to know what happened.
Mark replied, “She didn’t suffer.” He then confessed fully.
Mark said that on the evening of May 23, 1994, Kaye came to his apartment asking to play with his son. He let her in and took her tricycle to the kitchen. About ten minutes later, he heard Judy calling Kaye’s name.
He panicked, knowing Judy would be furious that he had let her daughter inside without permission. He went upstairs and strangled Kaye with his bare hands. Detective Crow had doubts about this version.
He suspected Mark had lured Kaye in with the intent to molest her, and that the missing shoelaces suggested premeditation. But Crow did not press, needing to know where the body was.
Mark described placing Kaye’s body in a laundry basket, covering it with clothes, and putting it in his car trunk. He then drove to his workplace, a company where he worked as a security guard. He parked near a back door, carried the basket inside, and climbed onto a huge 30,000-gallon tank filled with liquid coolant.
He opened the lid and dropped Kaye’s body in, first tying a heavy metal object to it. He disposed of her clothes but kept her earrings. He then returned home and joined the search.
He had removed the body before police even arrived.
Mark was arrested. His lawyer tried to withdraw the confession, but Crow had not violated any laws. Police went to the tank and recovered Kaye’s remains.
The decomposition was too advanced to determine the cause of death, but the identity was confirmed. Judy finally buried her daughter. Mark pleaded guilty to murder and was sentenced to a minimum of 25 years in prison.
The kidnapping charges were dropped as part of a deal.
But the story did not end there. In 2010, a cold case from 1988 was reopened. A 74-year-old woman named Viola Manville had been brutally murdered while walking in a Rochester suburb.
The original suspect, Frank Sterling, had been coerced into a false confession and spent 19 years in prison. DNA evidence from the reopened case matched Mark Christie. In 2011, Mark confessed to Viola’s murder, showing no remorse.
He received an additional 28 years. Frank Sterling was exonerated and received nearly $10 million in compensation, but died of a heart attack three years later at age 54.
Mark Christie remains in prison, eligible for parole in a few years. But the tragedy of Kayanne Poulton is a stark reminder of how a predator can hide in plain sight, and how a mother’s instincts were tragically correct. Judy had warned police about Mark, but the polygraph and alibi had cleared him.
The system failed Kaye. Now, her killer sits behind bars, but the scars of that sunny evening in 1994 will never fully heal. The truth, when it finally emerged, was as heinous as anyone could have imagined.
And it came through a wild twist: a wife’s phone call, a detective’s patience, and a killer’s ego.
