Rachel Morin: The Ma and Pa Trail Murder — A Complete Case Timeline

Rachel Morin was thirty-seven years old, a mother of five, and a regular on the Ma & Pa Heritage Trail in Bel Air, Maryland. On the evening of August 5, 2023, she left to walk and run that familiar path — and did not come home. The investigation that followed took nearly a year, spanned two coasts, and ultimately rested on a forensic technique that has changed how unsolved violent crimes are approached: investigative genetic genealogy (IGG). Victor Antonio Martinez-Hernandez was convicted of her murder in April 2025 and sentenced to life in prison without the possibility of parole.

This page collects the full case timeline, the details of how investigators identified her killer, and where the case stands as of mid-2026.

Who was Rachel Morin?

Rachel Morin was a Harford County resident who ran a housecleaning business and was, by all accounts of people who knew her, devoted to her children and active in her community. She had five kids. The Ma & Pa Heritage Trail — a wooded recreational path stretching through Harford County — was part of her regular life. It was a place to move, to breathe, to step away from the demands of a full household for an hour.

That ordinariness is part of why her death resonated so widely and so durably. She was not in a dangerous situation. She was doing something millions of Americans do every evening without incident. The violence that found her on that trail was not something she invited or could have anticipated.

Her mother, Patty Morin, became a consistent public presence in the months and years that followed — organizing remembrance walks along the trail, speaking at hearings, and keeping Rachel’s name visible. Patty Morin has spoken publicly about surviving a serious assault herself, decades earlier, and she brought that personal context to every public appearance on her daughter’s behalf. Whatever political currents attached themselves to the case afterward, the family’s message stayed constant and clear: Rachel was a person, a daughter, and a mother.

August 5, 2023: What happened on the Ma & Pa Trail

Rachel Morin left her home on the evening of August 5, 2023, heading for the Ma & Pa Heritage Trail. She told someone she loved where she was going. When she did not return and could not be reached by phone, her family became alarmed and went looking. Her car was found at the trailhead.

The next morning, August 6, searchers located her body in a wooded area off the trail near a drainage culvert. Investigators from the Harford County Sheriff’s Office classified the death as a homicide. The medical examiner’s findings, and the evidence at the scene, made clear she had been attacked, sexually assaulted, and killed.

Crime-scene examiners recovered biological evidence — including the attacker’s DNA. That profile became the central thread of the entire investigation.

How detectives identified Victor Martinez-Hernandez

The process of identifying Martinez-Hernandez unfolded in three distinct stages, each one building on the last.

Stage 1: CODIS and the dead end

The crime-scene DNA profile was uploaded to CODIS, the Combined DNA Index System — the FBI’s national database that compares unknown forensic profiles against DNA from convicted offenders and other cases. CODIS found no direct match. Martinez-Hernandez had never been entered into the offender database in a way that returned his name. The profile was precise and complete. It was simply attached to nobody on file.

What CODIS did eventually surface was a crime-to-crime link — not a name, but a connection. The same unidentified DNA profile matched evidence from a violent home invasion and assault that had occurred earlier that year in the Los Angeles area. The same unknown man had attacked in California and in Maryland. That revelation pulled in investigators from a second jurisdiction and confirmed that the search extended well beyond Harford County.

Stage 2: Forensic genetic genealogy with the FBI and Othram

To put a name to the profile, investigators worked with the FBI’s Baltimore field office and Othram, a Texas-based forensic laboratory that specializes in next-generation DNA sequencing for criminal investigations.

Othram’s process starts by extracting and sequencing far more of the DNA than a standard forensic kit produces — a full-genome or near-full-genome profile rather than the limited marker set used in CODIS. That richer profile is then searched against genealogical databases containing DNA uploaded voluntarily by members of the public who want to find relatives. The search does not look for the suspect himself. It looks for distant relatives — cousins, second cousins, people who share enough genetic material to appear as matches.

This is the core logic of investigative genetic genealogy: an offender who has never been tested cannot opt out of the database if a relative chose to participate. Genealogical databases contain millions of profiles, and even distant relatives share identifiable amounts of DNA.

Stage 3: Family tree work, convergence, and confirmation

Once distant-relative matches were identified, investigators and genealogists began the painstaking work of building family trees — tracing branches through public records (birth certificates, census records, marriage filings) forward through time until the branches converged on a living individual who fit the investigative profile. Over roughly nine months, that work produced a name: Victor Antonio Martinez-Hernandez.

Investigators then gathered a direct DNA sample from Martinez-Hernandez and compared it against the crime-scene profile. The match was confirmed. That confirmation is the legal standard that converted a genealogical lead into courtroom-grade evidence.

DNA and the cross-jurisdiction evidence

The Los Angeles home invasion connection proved significant in multiple ways. It demonstrated that Martinez-Hernandez had a documented history of violent offending prior to Rachel Morin’s murder. It placed his DNA in a second crime scene in a second state. And it widened the investigative net, bringing additional federal and law enforcement resources to bear on a case that might otherwise have remained a single-jurisdiction investigation.

The Harford County Sheriff’s Office, working in coordination with the FBI and state prosecutors, kept the case active and moving during a period — fall 2023 through spring 2024 — when no public announcement of progress had been made. The quiet sustained work of that period is what produced the arrest.

Charges, trial, and verdict

Victor Antonio Martinez-Hernandez was located in Tulsa, Oklahoma, and arrested in June 2024, approximately ten months after Rachel Morin’s death. He was extradited to Maryland and arrived at Martin State Airport on June 20, 2024.

His trial began April 1, 2025, in Harford County Circuit Court, with Circuit Judge Yolanda L. Curtin presiding. Prosecutors presented the DNA evidence connecting him to Rachel and to the scene, the cross-jurisdiction link to the Los Angeles crime, and the full record of the genetic genealogy investigation.

On April 14, 2025, the jury returned guilty verdicts on all counts after deliberating for less than an hour. He was convicted of:

• First-degree premeditated murder
• First-degree rape
• Third-degree sexual offense
• Kidnapping

The swiftness of the deliberation — under one hour for a four-count murder indictment — reflected the directness of the forensic evidence.

The sentence

On August 11, 2025, Judge Curtin imposed the maximum available penalty. Martinez-Hernandez was sentenced to life in prison without the possibility of parole, plus a consecutive life sentence, plus an additional 40 years. Members of Rachel’s family addressed the court at the sentencing hearing.

At the close of the hearing, Martinez-Hernandez indicated he intended to appeal the conviction. That appeal, as of mid-2026, remains pending and unresolved. The conviction and sentence are the matters of current public record. Prosecutors have expressed confidence the conviction will hold, and no reporting available at the time of writing indicates the sentence has been disturbed. As with any case under appeal, the most current status can be confirmed through Harford County Circuit Court records.

Where the case stands as of mid-2026

Victor Antonio Martinez-Hernandez is serving a sentence of life without parole plus a consecutive life term and 40 additional years for the murder, rape, and kidnapping of Rachel Morin. His appeal is pending.

Rachel’s family has continued to honor her memory with public events along the Ma & Pa Trail. Her mother has remained an active voice in public discussions about the case. The investigation itself — the DNA collection, the cross-jurisdiction link, the genetic genealogy process, and the arrest after a nationwide search — has been cited in discussions of how forensic genetic genealogy should be applied and governed going forward.

Frequently asked questions

Who was Rachel Morin? Rachel Morin was a 37-year-old mother of five from Harford County, Maryland. She ran a housecleaning business and was killed on August 5, 2023, while walking and running on the Ma & Pa Heritage Trail in Bel Air.

Who was convicted of Rachel Morin’s murder? Victor Antonio Martinez-Hernandez was convicted on April 14, 2025, in Harford County Circuit Court of first-degree premeditated murder, first-degree rape, third-degree sexual offense, and kidnapping. The jury deliberated less than an hour.

How was Rachel Morin’s killer identified through DNA? Crime-scene DNA was uploaded to CODIS, which returned no direct name match but linked the profile to a second crime in Los Angeles. Investigators then worked with the FBI and the forensic lab Othram to apply forensic genetic genealogy — sequencing a full DNA profile and searching genealogical databases for partial matches among distant relatives. Family tree work narrowed the search to Martinez-Hernandez. A direct DNA comparison confirmed the match.

What is forensic genetic genealogy (also called investigative genetic genealogy or IGG)? Investigative genetic genealogy (IGG) is a technique in which a detailed DNA profile from a crime scene is compared against voluntary genealogical databases (such as GEDmatch or FamilyTreeDNA) to find distant relatives of the unknown suspect. Genealogists then build family trees from those matches, tracing forward through public records until a likely suspect emerges. Traditional investigation and direct DNA testing confirm the match. The Golden State Killer case in 2018 is the best-known precedent.

What sentence did Victor Martinez-Hernandez receive? On August 11, 2025, he was sentenced to life without parole, plus a consecutive life sentence, plus an additional 40 years — the maximum penalty available.

Is Victor Martinez-Hernandez appealing his conviction? He indicated at sentencing that he intended to appeal. As of mid-2026 that appeal is pending. The conviction and sentence remain in effect.
