In the winter of 2024, a forensic analyst at the Virginia Department of Forensic Science in Richmond opened an evidence envelope that had been sealed in October of 1978 and had not been opened since. Inside was a single human hair, approximately four inches long, found on the collar of a woman’s blouse in a farmhouse outside Staunton, Virginia, forty-six years earlier. The technician who collected it in 1978 had bagged it, tagged it, logged it, and sealed it properly. But the technology to fully use it did not exist at the time, the case went cold, and the envelope sat in an evidence room through four decades of changing administrations and updating systems.

The analyst who opened it in 2024 used mitochondrial DNA sequencing, a method capable of extracting a genetic profile from a hair shaft even when the root, which contains nuclear DNA, is absent. The hair had no root. It did not matter. Four weeks later, the analyst had a profile.

Six weeks after that, through investigative genetic genealogy, she had a family. And eight weeks after the envelope was first opened in forty-six years, investigators had a name. The name was Harlan Booth Winslow. He was ninety years old and living in a retirement community in Harrisonburg, Virginia, twenty-six miles from the farmhouse where he had left that hair in October of 1978.

He had outlived the woman he killed by forty-six years. Her name was Margaret Louise Fain. She was fifty-three years old. She had grown up on that farm and died on that farm.

The Shenandoah Valley in October of 1978 was in the full throat of autumn, the Blue Ridge Mountains going rust and amber on either side of the valley floor. It was farming country that had been farmed for two hundred years, and the people who lived in it were rooted in a specific place. Margaret Fain had been born on the property outside Staunton in 1925. Her parents, Otis and Ruth Fain, had worked the same land since before the Depression.

Margaret attended school in Staunton and briefly a secretarial college in Roanoke in 1944, but came home in 1946 when her father’s health began to fail and someone needed to keep the operation running. She never left after that. By 1978, Margaret was fifty-three and had been running the farm alone since her mother’s death in 1969. It was a smaller operation than in her father’s time: some cattle, some hay, a kitchen garden.

She had never married. Her life was the farm and the community around it: the First Presbyterian Church in Staunton, where she played organ on Sunday mornings, and the Augusta County Farm Bureau, where she served on committees. She drove a 1972 Ford pickup truck, wore her gray hair in a bun, and had strong opinions about soil pH and the proper way to stake tomatoes. She had a neighbor named Harlan Winslow who owned the property sharing her eastern fence line.

He was forty-four years old in 1978, married with two grown children, and ran a small equipment repair operation out of a metal building on his property. He did handyman work for farms in the area, which meant he was on other people’s land regularly and knew where everything was and who was likely to be home at what hour. He had done work on Margaret’s property in 1976 and 1977. They had maintained a civil, slightly formal relationship.

On the evening of Thursday, October 12th, 1978, Margaret Fain did not appear at a Farm Bureau committee meeting in Staunton that she had chaired for three years and had never previously missed. The committee secretary tried calling the farmhouse at 7:30 p. m. There was no answer.

She drove to the farm after the meeting and arrived at approximately 9:15 p. m. She found the front door standing open, the kitchen light on, and the Ford pickup in the yard. She called the Augusta County Sheriff’s Office.

Deputies arrived at 9:47 p. m. The detective assigned was a twenty-two-year veteran named Investigator Thomas Quarles. Margaret was dead, killed in her own kitchen.

The farmhouse had not been ransacked, nothing was obviously missing, and her purse was on the kitchen counter with the evening meal she had been preparing still on the stove. Whatever had happened had happened quickly, to a woman who had answered her own front door without fear. The single hair was found by the forensics team on the morning of October 14th. It was on the collar of the blouse Margaret was wearing, four inches long, not hers.

Her hair was shorter and gray; this hair was darker with a slight wave. The technician bagged it, tagged it, sealed it, and logged it as item 78 of 114. It went into the evidence envelope. Investigator Quarles worked the case with the tools available to him in 1978.

He interviewed everyone in Margaret’s orbit. He interviewed Harlan Winslow on October 16th. Winslow was cooperative and said he had been home all evening on October 12th. His wife Cora confirmed it.

The interview lasted forty minutes. Winslow was noted as a neighbor with regular access to the property, interviewed, not a suspect. A farmhand with a less than amicable departure was eliminated by a provable alibi in West Virginia. A drifter seen in the area was located and cleared.

The hair was tested in November of 1978 under the forensic capability of the time. It was human, it was not Margaret’s, and it was from a male donor based on the scale pattern. That was as far as the science went. Without a root, there was no blood type analysis and no DNA.

There was a hair in an envelope and nothing to attach it to a person. Quarles worked the case for eight years after his retirement in 1981, on his own time. He died in 2003. The case had never been solved.

Margaret’s nephew Clifford Fain, her only surviving family, had been notified and handled the estate. By 1980 the farm was sold. By 1990 Clifford was living in Roanoke. He had been writing to the Augusta County Sheriff’s Office about his aunt’s case every five years with the patience of a man who does not believe patience will be rewarded but cannot bring himself to stop.

In 2010 he submitted a family reference DNA sample to the Virginia cold case registry. In 2018 he died of a stroke, not knowing. His daughter, a woman named Beth Fain Ogden, continued writing the letters after his death. She had never met Margaret.

In 2022, the Virginia Department of Forensic Science launched a cold case DNA initiative targeting pre-1990 cases with biological evidence that had never been subjected to modern testing. The envelope with the hair arrived at the Richmond lab in September of 2023. The forensic analyst assigned was Dr. Keysha Odom, who specialized in degraded and difficult samples and had worked the state lab for eleven years.

The hair had no root, a barrier for conventional nuclear DNA profiling, but not for mitochondrial DNA sequencing, which is found in the hair shaft rather than the root, exists in higher copy numbers, and degrades more slowly. Dr. Odom completed the mitochondrial sequence in January of 2024. The profile was uploaded to a genealogy research database in coordination with certified investigative genetic genealogist Patrick Euen, who had worked eight prior Virginia cold cases.

The search returned partial matches in February of 2024. A family with roots in Augusta County going back to the early 1900s resolved: a branch that included a man born in 1934 in Staunton, Virginia, who had married a woman named Cora Alcott in 1956 and operated an equipment repair business on a property sharing a fence line with the Fain farm. Harlan Booth Winslow. He was ninety years old, living at a retirement community called Shenandoah Pines, quiet and self-contained, known to staff as not given to conversation beyond the functional minimum.

His wife Cora had died in 2019. Investigators obtained a covert DNA sample from him in March of 2024, a coffee cup from the common room. The mitochondrial sequence was compared to the profile from the hair and was consistent. It established shared maternal lineage, powerful corroborating evidence combined with the totality of the investigative record: proximity, access, the original interview in which he had placed himself at home with his now deceased wife as his only alibi.

The Augusta County Commonwealth’s Attorney reviewed the evidence package in April of 2024 and authorized an arrest. On the morning of April 29th, 2024, Investigator Dana Merritt and two colleagues arrived at Shenandoah Pines and found Harlan Winslow in the common room eating breakfast. She introduced herself and told him why she was there. Winslow set down his spoon, looked at her, and said nothing.

He was placed under arrest and charged with first-degree murder. Bond was denied. He was remanded to the Augusta County Correctional Facility. Beth Fain Ogden was sixty-three and living in Charlottesville when Investigator Merritt called her in late April of 2024.

She was quiet on the phone for a long moment. Then she asked whether they were certain. Merritt told her about the hair, the envelope, the mitochondrial sequence, the genealogical work, and the coffee cup. Beth Fain Ogden said her father had written letters for forty years and never knew if anyone was reading them.

Merritt said, we read them. Legal proceedings were ongoing through the latter part of 2024, complicated by Winslow’s age and the nature of mitochondrial versus nuclear DNA evidence. His attorneys challenged the evidentiary weight of a mitochondrial match. The Commonwealth’s Attorney’s Office prepared to argue that in the context of the full investigative picture, access, proximity, opportunity, and the original false alibi relying on a witness now deceased, the evidence was sufficient.

A trial date was set. Whether Winslow lives long enough to hear a verdict remained genuinely uncertain. What is not uncertain is this. Margaret Louise Fain has a name on an active prosecution.

A sealed envelope opened after forty-six years produced a profile that produced a family that produced a man. A technician in 1978 who bagged it, tagged it, sealed it, and logged it created the conditions for a resolution that would not arrive in his lifetime but arrived nonetheless because the work was done correctly and the envelope held. And Beth Fain Ogden, who inherited a story and a habit of letter writing from a father who inherited it from a grief he could not put down, understood that the letters had not been futile. Someone had been reading them.

The envelope had been waiting for the right moment to be opened. Harlan Booth Winslow is ninety years old and facing trial for what he did when he was forty-four. He has had forty-six years of mornings that Margaret Fain did not get. The hair was sealed in an envelope in 1978 by a technician who believed, correctly, that the work mattered even if the result was not yet possible.

The result is now possible. The envelope has been opened. And in a retirement community in Harrisonburg, a man who thought that outliving a crime was the same as escaping it has learned at ninety years old that time was never the alibi he believed it to be. Justice, when it finally comes, does not ask how old you are.

It only asks what you did.
