Executive Summary
This document provides a comprehensive analysis of the investigation, prosecution, and broader implications of the murder of Rachel Morin on August 5, 2023, in Bel Air, Maryland. The case was solved through a combination of traditional detective work and cutting-edge forensic science, most notably investigative genetic genealogy, which identified the perpetrator, Victor Antonio Martinez-Hernandez, ten months after the crime.
Key takeaways from the case include:
The Perpetrator: Victor Martinez-Hernandez, a 24-year-old national of El Salvador, was identified as a serial predator with a pattern of escalating violence. Before murdering Morin, he was wanted for a murder in El Salvador and his DNA was linked to a home invasion and assault of a mother and her nine-year-old daughter in Los Angeles in March 2023.
Systemic Failures: The investigation highlighted significant gaps in immigration enforcement. Martinez-Hernandez had been deported three times in early 2023 before successfully entering the U.S. illegally on his fourth attempt, just months before committing the violent crimes in Los Angeles and Maryland. This has made the case a focal point in national debates on border security.
Technological Revolution in Forensics: The resolution of the case hinged on modern technology. A DNA match in the CODIS database linked the Maryland and California crimes. Data from Morin's Apple Watch established a precise timeline of her attack. Ultimately, investigative genetic genealogy, using public DNA databases, traced the unknown suspect's family tree to identify Martinez-Hernandez by name.
Legal Outcome: Following his arrest in Tulsa, Oklahoma, on June 14, 2024, Martinez-Hernandez was convicted by a Harford County jury on all counts, including first-degree murder and rape, after a deliberation of only 46 minutes. He was sentenced to two consecutive life terms without the possibility of parole, plus an additional 40 years, ensuring he will die in prison.
The case serves as a paradigm for modern homicide investigations, demonstrating the power of integrating digital evidence, advanced DNA analysis, and multi-agency cooperation while also exposing the devastating human cost of systemic failures.

1. The Victim and The Crime in Rachel Morin's Murder
Profile of Rachel Morin
Rachel Hannah Morin, 37, was a mother of five children, ranging in age from eight to nineteen at the time of her death. She was a self-employed business owner, operating her own cleaning service in the Bel Air, Maryland area. Described as a devoted mother, she was also a fitness enthusiast who regularly ran on the Ma & Pa Heritage Trail, a 6.25-mile converted railroad corridor in Harford County. Her routine was highly predictable, a factor that forensic modeling identified as a significant vulnerability.
The Attack: August 5, 2023
On the evening of Saturday, August 5, 2023, Rachel Morin parked her car near the Williams Street entrance to the Ma & Pa Trail for a routine run. Her digital footprint provided a precise timeline of her final moments:
6:29 PM: Seen on surveillance at a Wawa convenience store.
6:42 PM: Seen on surveillance leaving a Target store.
7:04 PM: Sent her last text message to her eldest daughter, Faye.
7:07 PM: Her Apple Watch recorded her heart rate spiking from a normal running pace to 115 beats per minute, indicating the start of the attack.
7:09 PM: Her heart rate plummeted to 62 beats per minute, marking the approximate time of death.
The attack was characterized by extreme brutality. The medical examiner's report detailed 15 to 20 distinct blunt force injuries to her head and face, caused by large rocks, as well as evidence of strangulation and sexual assault. Her body was discovered the following day, dragged approximately 150 feet off the trail and left in a drainage culvert.
2. Initial Investigation and Discovery
Rachel Morin was reported missing by her boyfriend, Richard Tobin, at 11:23 PM on August 5 after she failed to return from her run. Tobin, who had only been "Facebook official" with Morin for five days, was initially a person of interest due to his recent relationship with the victim and a prior criminal record. However, he was quickly cleared by investigators through DNA evidence and a confirmed alibi.
A massive community search was organized on the morning of August 6. At 1:07 PM, a volunteer searcher, Evan Knapp, discovered Morin's body in a drainage culvert near the trail. The scene was immediately secured, and the case was officially declared a homicide investigation.
3. The Forensic Breakthrough: A Nationwide Manhunt
The investigation's pivotal moment came on August 17, 2023, just twelve days after the murder.
The CODIS Hit
DNA evidence recovered from Rachel Morin's body was uploaded to the FBI's Combined DNA Index System (CODIS). The system registered a direct match to DNA collected from an unsolved crime scene in Los Angeles, California.
The Los Angeles Crime: On March 26, 2023, a shirtless Hispanic male suspect broke into a home and assaulted a mother and her nine-year-old daughter. The suspect fled but left behind DNA evidence and was captured on a Ring doorbell camera.
This match transformed the local homicide into a multi-jurisdictional manhunt for a serial predator who had committed violent crimes on both coasts. A multi-agency task force was formed, including the Harford County Sheriff's Office, the FBI, and the LAPD.
4. The Power of Genetic Genealogy
With the suspect's DNA profile but no name, traditional investigative methods stalled. The task force turned to investigative genetic genealogy, a technique successfully used to identify the Golden State Killer.
The Scientific Hunt
The DNA profile was sent to Othram Labs, a private laboratory specializing in forensic genealogy. Scientists created an enhanced SNP profile and uploaded it to public genealogy databases like GEDmatch, searching for distant relatives of the unknown suspect who had voluntarily submitted their own DNA for ancestry purposes.
Identification and Location
After months of painstaking work building out complex family trees, the genealogy team had a breakthrough on May 20, 2024—what would have been Rachel Morin's 38th birthday. They traced the genetic connections to a family from El Salvador with relatives living in the United States, ultimately identifying the suspect as Victor Antonio Martinez-Hernandez, age 23.
Subsequent investigation of his digital footprint placed him in Tulsa, Oklahoma.
5. Capture and Extradition
A surveillance operation was launched in Tulsa. On June 14, 2024, Martinez-Hernandez was located and arrested at a local sports bar called The Anchor (also referred to as Los Dos Amigos). He initially provided a false name, "Carlos Mendez," but was positively identified through fingerprints which matched records from his prior deportations.
He was extradited to Maryland to face charges for the murder, rape, and kidnapping of Rachel Morin.
6. The Trial and Verdict
The trial of Victor Martinez-Hernandez began on April 1, 2025, in Harford County Circuit Court, presided over by Judge Yolanda L. Curtin.
The Prosecution's Overwhelming Case
State's Attorney Alison Healey presented a case built on an avalanche of scientific and circumstantial evidence.
The Verdict
On April 14, 2025, after nine days of testimony from over 30 witnesses, the jury deliberated for just 46 minutes before returning a verdict of guilty on all counts, including first-degree premeditated murder, first-degree rape, and kidnapping.
7. Sentencing and Reckoning
Sentencing occurred on August 11, 2025. The hearing was dominated by powerful victim impact statements from Rachel Morin's family.
Patty Morin (Mother): "The brutality of her murder will haunt us for the rest of our lives... You are a predator who came here to hunt."
Children's Statements (read or played): The children spoke of a future without their mother at milestones like graduations and weddings. The youngest stated, "Now I have to spend more time without you than I did with you."
Martinez-Hernandez declined to make a statement. Judge Curtin, noting his complete lack of remorse and the "coldness, dismissiveness, and a callous attitude" described in his psychological evaluation, handed down the maximum possible sentence: two consecutive life terms without the possibility of parole, plus an additional 40 years.
8. Key Themes and Broader Implications
Systemic Failures and Policy Impact
The case became a flashpoint for national debate on immigration policy. It was revealed that Martinez-Hernandez was wanted for murder in his native El Salvador and had been deported from the U.S. three times in January and February 2023 before making a fourth, successful illegal entry on February 13, 2023. This history led to widespread calls for stricter border enforcement and better information sharing between international law enforcement agencies.
Community and Family Aftermath
The murder irrevocably changed the Bel Air community's sense of safety. In response, Harford County invested in a new security system for the Ma & Pa Trail, installing over 100 AI-enabled cameras with threat detection capabilities.
For Rachel Morin's family, the legal victory provided accountability but not closure. Her five children were separated and are now being raised in different households by their respective fathers. The family has continued to advocate for policy changes in Rachel's name.
