Arkansas 1991 cold case solved after 32 years. Justice for Sabrina Underwood. She was 19 years old.
She was doing something that many young people did in rural Arkansas in the early 1990s, hitchhiking on a state highway, trying to get somewhere, relying on the goodwill of strangers in the way that people without cars and without money in rural America sometimes must.
On January 20th, 1991, Sabrina Underwood’s mother dropped her off near Bear Creek in Boone County, Arkansas.
Sabrina was planning to hitchhike to the North Central Unit State Prison in nearby Calico Rock to visit her boyfriend who was incarcerated there.
A visit she had made successfully the previous week, moving through the same geographic corridor by the same method without incident.
She never arrived. When her boyfriend called to ask why she hadn’t come for her scheduled visit, a missing person’s report was filed.
Three months later in April 1991, hunters found a bundle of Sabrina’s clothing and human remains in a location near the route she would have been traveling.
The remains were eventually identified as Sabrina’s. The medical examiner’s determination of cause of death was undetermined, an acknowledgement that the condition of the remains after 3 months in the Arkansas woods had not allowed a specific cause to be established with certainty.
The case was worked. No suspect was charged. It went cold. And then, 32 years later, a letter written by a prisoner in a maximum security facility produced the confession that the investigation had never been able to generate through any other means.
Before we talk about Rick Allen Headley and the letter and the plea, you have to understand who Sabrina Underwood was and what 32 years of an undetermined death did to the family that waited for an answer.
Boone County, Arkansas in January 1991 was rural Ozarks country. Forested hills and narrow state highways, small communities organized around the agricultural economy and the church calendar.
A landscape that is beautiful in the way that Appalachian adjacent terrain is beautiful and that carries in its beautiful hollows all the poverty and isolation and limited mobility that rural poverty and isolation produce.
The hitchhiking culture that existed in rural Arkansas in 1991 was not the romantic hitchhiking of the post-war imagination.
It was the practical mobility solution of people without cars in places without public transit.
People who needed to get somewhere and had to find rides because the alternatives were not available to them.
Sabrina Underwood was 19 years old and was trying to visit her boyfriend in prison and had gotten there that way the week before without a problem.
The problem came the following week when the man who stopped for her was not the kind of stranger that the assumption of goodwill in rural hitchhiking is built around.
Rick Allen Hedley was not a random stranger in the statistical sense. He had a history.
He would go on to demonstrate in the years after January 1991 what kind of person he was.
In 2018, he stabbed his estranged wife to death and pleaded guilty to capital murder.
He was sentenced to life in prison and transferred to the Varner Maximum Security Unit where he continued to exist in the penal system of the state of Arkansas while the case of Sabrina Underwood’s death remained officially undetermined.
In 2022, another inmate at the facility where Headley was housed contacted the Madison County Sheriff’s Office with information from a local lawyer.
The lawyer’s client, Headley, had written a letter in which he confessed to killing Sabrina Underwood.
The letter was specific in ways that general confession letters are not. The details matched what investigators knew about the case in ways that false confessions typically do not.
Arkansas State Police investigators were notified. They interviewed Headley at the Varner Unit in August 2022.
He admitted to writing the confession letter and provided additional details about Sabrina’s death in the interview.
He told investigators that Sabrina had tried to extort money from him during the encounter.
A claim whose truth or falsity cannot be established from the available information, and said that this was the precipitating circumstance of what happened.
He said, at the time of the interview, that he hoped no one else had been arrested for the murder.
That statement, the expression of concern that an innocent person had been blamed, is an unusual element in a confession that came 32 years after the crime.
And it is consistent with the profile of a man who had been carrying the knowledge of what he had done across those three decades, and who, at the end of that carrying, chose to put it down in the form of a written confession to a lawyer.
Headley was charged with first-degree murder in October 2023. He pleaded guilty to the charge in 2024 and was sentenced to an additional 40 years in prison.
The sentencing was made in the context of a man already serving a life sentence for the 2018 capital murder conviction.
A sentence structure in which the additional 40 years is largely symbolic in terms of the practical consequences for Headley’s freedom, since he will not be leaving prison under either sentence.
What the 40 years represents, in the cases where a person already serving life is sentenced to additional time, is the formal legal acknowledgement that the earlier crime also happened, and also mattered, and also deserves an accounting from the system.
Even when the practical consequence of that accounting is indistinguishable from what was already in place, Arkansas State Police Colonel Mike Hagar, in announcing the resolution of the case, said, “We will never give up on finding justice for families like the Underwoods, who still suffer the pain of Sabrina’s absence.”
Sabrina’s family, who had been told by the medical examiner in 1991 that the cause of death was undetermined, and who had spent 32 years without knowing what had happened to their daughter and sister on that January highway, received the confirmation of what they had long suspected.
Sabrina had been murdered by a man who picked her up while she was hitchhiking, and who then killed her in Arkansas in 1991, and went on with his life until his life eventually brought him to a maximum security prison cell in Arkansas, where he wrote a letter.
The specific mechanism of the confession, a letter written by a prisoner, reviewed by a lawyer, transmitted to the authorities, is one of the less common ways that cold case confessions arrive, and it is one that raises questions about the circumstances that produced it.
Headley was already serving life in prison for a 2018 murder when he wrote the 1991 confession.
The incentive structure for confessing to an additional crime when you are already serving a life sentence is not obvious.
And the fact that he confessed anyway suggests that the confession was not primarily motivated by self-interest.
The statement that he hoped no one had been arrested for the murder suggests a moral concern.
However late and however imperfect about the consequences of the crime he had committed. He had carried the knowledge of Sabrina’s death for 32 years.
He put it down in a letter. The letter found its way to the people who needed to hear it.
Sabrina Underwood was 19 years old. She was hitchhiking on a January highway in Boone County trying to get to the prison in Calico Rock to visit her boyfriend.
She had done the same trip the week before without incident. The incident came on January 20th, 1991 when the man who stopped for her was someone for whom a 19-year-old hitchhiker was an opportunity.
Her remains were found 3 months later. Her death was listed as undetermined for 32 years.
Her killer wrote a letter and pleaded guilty and received a sentence that added to the life sentence he was already serving.
The family has an answer. The case is closed. What does it say about the weight of guilt that a man who is already serving life in prison chooses to confess to an additional murder committed 32 years earlier?
What drives a person to put that kind of information in a letter after three decades of silence?
And what does it mean for the Underwood family that the answer came through the specific and unusual mechanism of a prisoner’s confession rather than through any active investigative development?
Leave your thoughts below. Say her name. Sabrina Underwood. 19 years old, Boone County, Arkansas, January 20th, 1991.
Subscribe because the cases where the confession came 32 years late deserve the same attention as the ones where it came immediately.
The question of what produces a confession after three decades of silence is one that forensic psychology has examined in various contexts.
And the answers are generally complex and specific to the individual. In Hedley’s case, the most available interpretation is that the confession came in the context of a man who had already been convicted of a second murder and who was at a specific point in his life, incarcerated for life, facing his own mortality in the way that lifers do, in a legal environment where the confession to an additional crime would have minimal practical impact on his freedom, where the carrying of the knowledge became more burdensome than the releasing of it.
That is speculative. The actual internal experience of a man who killed a 19-year-old hitchhiker in 1991 and then killed his wife in 2018 and then wrote a confession letter from a maximum security prison in Arkansas is not accessible to outside observers in any way that goes beyond speculation.
What is not speculative is the impact of the confession on Sabrina Underwood’s family. They had been told in 1991 that the cause of death was undetermined, a classification that is technically accurate when the state of the remains does not allow a specific cause to be established.
But that carries with it a specific uncertainty that is deeply unsatisfying for a family that knows their daughter was murdered.
The classification undetermined is not no crime occurred. It is the evidence does not allow us to say with certainty what crime occurred.
Families living inside that classification live in a specific liminal state. Certain that something terrible happened.
Unable to get official confirmation of what it was. Unable to direct their grief at a specific responsible party because no responsible party has been officially named.
Hedley’s confession and guilty plea ended the liminal state. The cause of death is no longer undetermined.
The person responsible has been identified and has pleaded guilty. The 40-year sentence adds to the life sentence in ways that are symbolically significant even when they are practically indistinguishable.
Sabrina Underwood’s family has the specific certainty that the confession and the guilty plea provide.
The legal acknowledgement that she was murdered by this specific person in January 1991. That certainty is what they were owed from the beginning and what they waited 32 years to receive.
The Arkansas State Police’s investigation of this case across the decades between 1991 and the 2022 confession tip is a story of institutional persistence.
The maintenance of a case file across 32 years. The response to the tip when it came.
The investigation of Hedley at the Varner Unit. The charge and prosecution that followed. The specific detective or investigator who kept the Underwood case active across those decades is not prominently named in the public record of the case, which is common in long-running cold cases where the active work is spread across multiple careers and multiple assignments.
What the institutional record shows is that the case was maintained, the evidence was preserved, and the response to the 2022 tip was prompt and thorough.
That institutional maintenance is what made the confession tip actionable when it came. Sabrina Underwood, 19 years old, Arkansas State Highway, January 20th, 1991, hitchhiking to see her boyfriend, found 3 months later in the woods, cause of death listed as undetermined for 32 years.
Her killer convicted of another murder in 2018. His confession letter in 2022. His guilty plea.
40 additional years. Her family’s certainty at last. Say her name. Subscribe. Because the cases where the confession came through an unusual channel and decades late are the cases that prove that justice can arrive from unexpected directions when the institutional will is maintained and the evidence is preserved.
The Underwood family received the call in 2022 that changed the category of their grief, from the grief of not knowing to the grief of knowing.
Those two griefs are different, and the second, while not lighter, is more navigable. It has an object.
It has a name. The name is Rick Allen Headley, and he is in prison for life.
Sabrina Underwood’s name is in the record of the Arkansas State Police, not as an undetermined cause case, but as a solved homicide.
That is the difference that 32 years of waiting and one prisoner’s letter made. Subscribe and keep saying her name.
The rural Arkansas cold case landscape is one that receives less national attention than cold cases from major metropolitan areas, and that disparity is worth naming directly.
Cases from New York City or Los Angeles or Chicago receive coverage because the media infrastructure of those cities generates and sustains coverage in ways that smaller markets do not.
Cases from Boone County, Arkansas in 1991 received the coverage that local Arkansas media provides, which is real and genuine, but limited in reach.
The families of victims in rural cold cases carry the same grief as the families of victims in nationally covered cases, and they deserve the same sustained attention.
They do not always receive it. Sabrina Underwood’s case received renewed national attention in the context of the 2022 arrest and 2024 plea, a brief wave of coverage that named her and described what had happened, and then moved on to the next case.
This is the standard pattern of cold case news coverage, a spike of attention when the arrest comes, and then the silence that follows when the next story is more recent.
The families of victims in cases like this one live in that silence before and after the spike.
They live in the years between the crime and the confession, and then they live in the years after the conviction in a world that has largely moved on from the specific story that upended their family in 1991.
That is the normal condition of grief in a society organized around the news cycle.
What can be done differently? What this channel exists to do is to ensure that the names persist beyond the news cycle, that the stories are told with the fullness they deserve, rather than in the compressed format of a breaking news segment, and that the families of victims in rural cold cases receive the same quality of attention as the families of victims in cases that generate national coverage.
Sabrina Underwood was 19 years old and died in rural Arkansas in January 1991, and she deserves as much care in the telling of her story as any other victim of violent crime.
She was 19. She was hitchhiking to visit the person she loved. The man who stopped for her killed her and carried the knowledge for 32 years.
His letter brought the answer. Her family received the certainty they deserved. Say her name.
Sabrina Underwood. Subscribe. The Arkansas State Police has been working cold cases from across the state’s rural counties with the combination of modern forensic tools and the specific institutional knowledge that career investigators develop across long service in small agencies.
The cases that the state has resolved in recent years, including Sabrina Underwood’s, demonstrate that the combination of maintained evidence, institutional persistence, and responsiveness to tips from unexpected sources can produce accountability even when decades have passed.
The Underwood case did not resolve through DNA genealogy or through a CODIS hit, or through any of the forensic technology that has driven so many recent cold case resolutions.
It resolved through a letter, through a prisoner who had decided, for whatever internal reasons moved him, to put what he had done in writing.
Through the institutional response to that letter that produced an interview and a confirmation and a charge.
The old tools still work. The new tools are additions to the toolkit, not replacements for it.
What the combination of old and new tools, the institutional persistence that maintained the case file, the responsiveness to the tip, the interview technique that produced the confessions confirmation, the charge and prosecution that followed, produced was the specific outcome that Sabrina Underwood’s family deserved in 1991 and received 32 years late.
They deserved it. They waited. They received it. The accounting is imperfect in the timing.
It is real in the outcome. Sabrina Underwood was 19 years old. She is named in Arkansas’s cold case resolution records as a solved homicide.
Subscribe and keep watching are the ones where the answer came late and the people who waited for it deserve to be recognized.
The 40-year sentence added to Headley’s existing life sentence is the formal record of the state’s acknowledgement that what happened to Sabrina Underwood on January 20th, 1991 was a crime and that the person who committed it has been held accountable.
Sabrina Underwood’s name is in that record. Say it. Keep saying it. Subscribe.
