John Price Hayter Jr.: The Revolving Door Killer
Overview
John Price Hayter Jr. was an American serial killer whose violent criminal career spanned 33 years, a grim testament to a justice system's repeated failure to keep a dangerous man from society. Hayter's life was a cyclical pattern of crime, incarceration, parole, and murder. Between 1953 and 1986, he was convicted of killing three people in Texas and Florida: a fellow inmate during his first prison term, a teenage girl just two weeks after being paroled, and an elderly woman months after being paroled a second time.
His victims were chosen out of convenience and opportunity, their lives brutally cut short during his brief periods of freedom. Hayter’s methods varied—a pitchfork, a gun, a plastic tie—but his capacity for lethal violence was constant. He was a drifter and a lifelong criminal who seemed incapable of rehabilitation. Each time the prison doors opened for him, another life was tragically lost. After his final crime spree in 1986, he was captured and sentenced to his third life term, ensuring he would never be free again. He died in a Florida prison in 1995, leaving behind a legacy of sorrow and questions about the parole system that enabled his deadly pattern.
Early Life and Criminal Beginnings
John Price Hayter Jr. was born in Waco, Texas, on September 28, 1933. Little is publicly known about his childhood or upbringing, but his adult life was defined by near-constant conflict with the law. His formal criminal record began when he was a teenager. On November 29, 1952, at the age of 19, Hayter stole a 1951 Packard 200 in Austin, Texas. He drove the stolen vehicle back to his hometown of Waco, where he was quickly apprehended by law enforcement.
Brought to trial, Hayter pleaded guilty to the charge of automobile theft. The court handed down a two-year prison sentence. To serve his time, he was sent to the Ramsey Unit, a state prison farm operated by the Texas Department of Corrections in Brazoria County. It was in this controlled environment, surrounded by guards and other inmates, that Hayter's capacity for violence would first turn deadly.
The Murder of Leroy Oscar Martin
On August 18, 1953, just over seven months into his two-year sentence, Hayter was part of a prison work crew bailing hay in the fields of the Ramsey Unit. During the workday, an argument reportedly erupted between Hayter and another inmate, 18-year-old Leroy Oscar Martin. The details of their dispute have been lost to time, but its conclusion was swift and brutal. Hayter grabbed a pitchfork, a common farm tool, and used it as a weapon, stabbing Martin. The attack was fatal, and Leroy Martin died on the spot.
The prison murder led to a new conviction for Hayter. His relatively minor two-year sentence for auto theft was voided and replaced with a life sentence for murder. Despite the gravity of the new sentence, it carried with it the possibility of parole, a provision that would have devastating consequences decades later. Hayter was just 19 years old when he was condemned to a life behind bars for the first time.
Parole and the Murder of Linda Ruth Pibil
For the next 21 years, John Price Hayter remained incarcerated in the Texas prison system. Then, in the spring of 1974, the Texas Board of Pardons and Paroles granted him his freedom. He returned to Waco and secured a job at a machine shop, seemingly ready to reintegrate into society. But his commitment to a lawful life, if it ever existed, was fleeting. His freedom would last only two weeks.
On July 23, 1974, Hayter drove to the nearby town of Abbott, Texas, and entered Robertson's Hams, a local store. He intended to commit a robbery. The lone cashier on duty was 17-year-old Linda Ruth Pibil, the daughter of Mr. and Mrs. John Pibil of Abbott. Hayter not only robbed the store of approximately $300 but also kidnapped the young woman.
He forced Linda into a vehicle and drove to a secluded rural area. There, he sexually assaulted her before shooting her to death. Her body was later discovered near Fort Hood by a pair of soldiers, miles from where she had been abducted. The senseless and brutal murder of the local teenager sent a wave of fear and grief through the small Texas community.
Investigation and Second Life Sentence
Hayter remained at large for a month following Linda Pibil's murder. His criminal activities, however, did not cease. In late August 1974, he targeted another woman in Lacy Lakeview, a suburb of Waco. Posing as an electrician, he gained access to a woman's home. Once inside, he threatened her and her baby with a switchblade and forced her to drive him around in her car.
The woman's grandmother grew suspicious and contacted the police. Authorities located the vehicle and a high-speed chase began. During the pursuit, the quick-thinking victim managed to leap from the moving car to safety. The car subsequently crashed into a police vehicle, and Hayter, who was still inside, was injured but survived. He was arrested at the scene.
In the subsequent investigation, witnesses from the Robertson's Hams robbery identified Hayter as the man who had abducted Linda Pibil. He was charged with her murder and rape, as well as the kidnapping in Lacy Lakeview. He was convicted on all counts and, for the second time in his life, was sentenced to life in prison.
Another Parole, Another Murder: Teena Ambrose
Hayter served only 12 years of his second life sentence. In a decision that would prove fatal, the Texas parole board once again granted him release in June 1986. This time, Hayter did not stay in Texas. He became a drifter, making his way across the country and financing his travels through burglaries and thefts. By September, his journey had taken him to Lakeland, Florida.
On September 15, 1986, Hayter broke into the apartment of 80-year-old Teena Ambrose, a widow who lived alone. He overpowered the elderly woman, tied her up, and sexually assaulted her. He then strangled her to death, using the plastic tie from a rain bonnet as a ligature. After murdering Ambrose, Hayter stole her 1966 Plymouth Fury and fled.
He drove the stolen car to Delray Beach, Florida, where he abandoned it. His crime spree continued as he then broke into the home of an elderly couple. He tied them up at gunpoint and robbed them, stealing their 1986 Mercury Marquis to make his getaway.
Investigation and Capture
Hayter fled Florida in the stolen Mercury, heading west. His cross-country flight came to an unceremonious end in Grants, New Mexico, when local police officers pulled him over and arrested him for driving the stolen vehicle.
During questioning by a New Mexico detective, Hayter began to talk. He voluntarily confessed to the crimes he had committed in Florida, including the robbery and murder of Teena Ambrose. Investigators were able to further link him to his criminal past by a distinctive tattoo on his forearm: an outline of the state of Texas with the word "Texas" inscribed within it. Florida authorities were notified, and the process of extradition began.
Trial and Final Conviction
John Price Hayter was returned to Polk County, Florida, to stand trial for the murder of Teena Ambrose. The trial took place in a Bartow courtroom in February 1987. The prosecution's case was built on Hayter's own confession and damning physical evidence. They played a taped conversation between Hayter and the New Mexico detective in which he admitted to the robbery and to tying up Ambrose. In the recording, Hayter claimed he did not mean to kill her, suggesting she might have choked on the gags he used.
This self-serving claim was systematically dismantled by the state's medical examiner, Dr. James Holimon. Dr. Holimon testified that the plastic tie around Ambrose's neck was so tight that it had broken her larynx, making it impossible for her to breathe. He concluded that the combination of the tight ligature and the gag in her mouth was a deliberate act designed to silence her permanently and ensure her death.
The jury found Hayter's account unbelievable. They convicted him of first-degree murder, burglary, and robbery. Given the brutal nature of the crime and the aggravating circumstances, he was eligible for the death penalty, a sentence the victim's family strongly supported. However, the jury recommended life imprisonment, and the judge followed the recommendation. As the verdict was read, Hayter, then 53, reportedly showed no emotion, calmly chewing on cough drops. He was sentenced to his third and final life term.
The Victims
- Leroy Oscar Martin, 18 — August 18, 1953, in Brazoria County, Texas. An inmate at the Ramsey Unit prison farm, his life was tragically taken by a fellow prisoner during a workplace argument.
- Linda Ruth Pibil, 17 — July 23, 1974, near Abbott, Texas. A high school student working as a cashier, she was remembered as the beloved daughter of John and his wife. Her life was violently cut short during a robbery, abduction, and assault.
- Teena Ambrose, 80 — September 15, 1986, in Lakeland, Florida. A widow living independently in her own apartment, she was the victim of a brutal home invasion, sexual assault, and murder.
Death in Prison
Following his 1987 conviction in Florida, John Price Hayter Jr. was never a free man again. The revolving door of the parole system had finally been sealed shut. He spent the last years of his life incarcerated within the Florida prison system. On February 21, 1995, at the age of 61, Hayter died in custody in Jacksonville. His death marked the quiet end to a life defined by violence and a chilling pattern of murders that were as preventable as they were tragic.
