Authorities have lauded the use of a controversial forensic technique in the resolution of the murder case of Rachel Morin, a mother of five who was killed while walking on the Ma & Pa Heritage Trail in Harford County last August. Federal officials revealed at a news conference on Saturday that they had utilized forensic genetic genealogy to develop a comprehensive DNA profile of the suspect, leading them to Victor Martinez-Hernandez as the alleged perpetrator.

Forensic genetic genealogy has gained prominence in recent years after being used to identify the “Golden State Killer” in 2018. This investigative technique involves comparing a DNA profile against consumer genealogy databases, in addition to traditional law enforcement resources. While it has proven to be a powerful tool in solving cold cases, concerns have been raised about genetic privacy and the lack of regulation surrounding the practice.
Maryland became one of the first states to place limits on forensic genetic genealogy in 2021, but the technique remains largely unregulated across the country. By using DNA sequences to create a family tree of potential relatives, investigators can uncover leads that may help solve cases that have gone cold for years.
In the case of Rachel Morin, forensic evidence was sent to private labs for DNA evaluation and analysis, ultimately leading to the identification of Martinez-Hernandez as the suspect. Othram, a biotech company specializing in forensic genetic genealogy, played a crucial role in developing a comprehensive DNA profile from the evidence collected at the crime scene.
The detailed DNA profiles created by Othram allowed investigators to trace the biological family tree of potential suspects, ultimately leading them to Martinez-Hernandez. The suspect is currently in Oklahoma awaiting extradition to face murder and rape charges in Harford County.

Forensic genetic genealogy has expanded law enforcement’s ability to identify suspects who may not be found through traditional databases like CODIS. Othram is supporting legislation in Congress to allocate federal funds for state labs to handle forensic genealogy and measure its success in solving cold cases.
While the technique has proven to be a valuable tool in solving crimes, it raises questions about consent and privacy. The practice relies on sensitive genetic information volunteered by distant relatives of suspects, who may not be aware that their DNA is being used for law enforcement purposes.
As the investigation into Rachel Morin’s murder continues, authorities are working to piece together the final details that led to the arrest of Martinez-Hernandez. The use of forensic genetic genealogy has brought closure to a case that shocked the community and captured national attention, highlighting the evolving landscape of forensic science in modern crime-solving..
