Welcome to the first issue of The Living Edition.
You signed up for the Rachel Morin case file, and this issue delivers on that promise: the timeline, what the evidence actually showed, and the one lesson from this case worth carrying with you. Every week, this newsletter will do the same thing for one case — the facts as the record shows them, the victims kept at the center, and no invented drama. The real story is always enough.
Who Rachel was
Rachel Morin was 37 years old, a mother of five from Bel Air, Maryland. She was a runner. The Ma & Pa Heritage Trail, a wooded rail-trail that runs through Harford County, was her regular route. On the evening of August 5, 2023, she went out for a run and did not come home. Her boyfriend reported her missing that night. Her car was still parked at the trailhead.
She was found the next day, just off the trail. Investigators determined she had been raped and murdered.
What the evidence showed
From the scene, investigators recovered a complete DNA profile of an unknown male. They submitted it to CODIS, the FBI's national DNA index. It produced a match — but not a name.
The profile matched DNA from a home-invasion assault in Los Angeles in March 2023, five months earlier and 2,600 miles away. The same unidentified man was connected to both crimes. And that is where the trail appeared to end, because CODIS can only match a profile to a person if that person's DNA is already in the system from a prior arrest or conviction. This man had never been arrested in the United States. The database knew his DNA by heart and had no idea who he was.
For nine months, that was the state of the case: flawless physical evidence pointing at no one.
How they found him
The break came from forensic genetic genealogy — the same family-tree science that identified the Golden State Killer. A specialized laboratory, Othram, developed an advanced DNA profile from the evidence. Then a team at the FBI's Baltimore field office did the slow part: building a family tree outward from distant relatives whose DNA appeared in genealogy databases, narrowing branch by branch toward one man.
The tree led outside the United States, into El Salvador, where authorities already wanted a man named Victor Martinez-Hernandez in connection with the killing of a young woman before he fled the country in 2023.
The genealogy lead that finally produced his name surfaced on May 20, 2024. It would have been Rachel's 38th birthday.
On June 14, 2024, FBI agents and Tulsa police officers arrested Martinez-Hernandez at a bar in Tulsa, Oklahoma. In April 2025, a Harford County jury convicted him of first-degree premeditated murder, first-degree rape, kidnapping, and a third-degree sexual offense. On August 11, 2025, he was sentenced to two consecutive life terms without the possibility of parole, plus 40 years. His lawyers have indicated an appeal; the conviction stands.
The one lesson worth keeping
Rachel did nothing wrong, and nothing in this case should be read as a list of things she should have done differently. She ran a popular public trail in her own town, as thousands of people safely do every day.
The lesson is about time. Rachel was reported missing within hours, and that speed mattered: the scene was located and processed quickly, and the DNA evidence that ultimately convicted her killer was recovered intact. If someone you love runs, hikes, or walks alone, the single most useful habit is simple and free — know their route, and act early when something feels wrong. Hours matter more than almost anything else an ordinary person can control.
Going deeper
The full account of this case — the complete timeline, the investigation as it unfolded, the manhunt, the trial, and the family's two-year fight to see it through — is in our book, The Trail: The Murder of Rachel Morin. It is $5.99, and you can find it with the rest of our catalog at https://cassiancreed.com/books/?utm_source=beehiiv&utm_medium=email&utm_campaign=living_edition_01 — if this issue gave you something, the book is the whole story, told the same way: victims first, sourced, and honest.
Next Sunday
Issue 02 takes on a case where the science said one thing and the first headlines said another — and what it took to close that gap. Same standard: the record, the victims, and nothing invented.
