Forensic Genetic Genealogy (FGG) has emerged as one of the most transformative tools in modern forensic science. By combining advanced DNA analysis with genealogical research and large-scale public database matches, investigators can now identify unknown human remains, solve long-standing cold cases, and restore identity to those who have been missing for years. This innovative technique bridges science, technology, and human stories—yet it also raises important policy and ethical questions that must be addressed.
What Is Forensic Genetic Genealogy?
FGG uses DNA profiles from unidentified remains and compares them with genetic data available in public or open genealogy databases. When partial matches—such as distant cousins—are found, genealogists reconstruct family trees to narrow down potential identities.
This method goes beyond traditional forensic DNA matching and offers powerful new insights, especially in cases where standard databases like CODIS provide no results.
Investigative Impacts: How FGG Is Transforming Casework
1. Solving Decades-Old Cold Cases
FGG has enabled investigators to crack cases that remained unsolved for 20, 30, or even 50 years. By using extended family matches, it provides leads that were once impossible to generate.
2. Identifying Unknown Human Remains
For nameless victims—often referred to as "John Does" and "Jane Does"—FGG has become a breakthrough tool. It helps bring closure to families and supports accurate record restoration for the deceased.
3. Accelerating Investigations
Instead of spending years on conventional methods, investigators can now discover a victim’s identity in weeks or even days, speeding up justice and making resources available for other cases.
4. Strengthening Collaborative Forensic Work
FGG encourages partnerships among forensic laboratories, genealogists, law enforcement agencies, and database companies, creating a more connected forensic ecosystem.
