Investigative Genetic Genealogy: The Intersection of DNA and Crime Solving

Investigative genetic genealogist

An investigative genetic genealogist plays a pivotal role in solving cold cases, some of which have been unresolved for decades. By blending forensic science with genealogical research, this cutting-edge method has become an essential tool in law enforcement. DNA from crime scenes, once a dead end, can now lead investigators to suspects through family connections. This powerful intersection of science and genealogy has revolutionized crime solving, offering new hope in previously unsolvable cases.


As IGG continues to grow, forensic science technicians must broaden their expertise. Those interested in this field now need advanced education in DNA analysis and genealogy, alongside specialized certifications, to stay ahead in this rapidly evolving industry.

 

The Role of DNA in Forensics: From Fingerprinting to Genealogy

In the field of forensics, the role of DNA has expanded dramatically. What began as a method for direct identification—similar to fingerprinting—has now evolved into a powerful tool for solving crimes using familial DNA, especially through investigative genetic genealogy.

 

The Evolution of DNA in Crime Solving

DNA was initially used in forensics for straightforward matching—comparing DNA from crime scenes to samples in criminal databases. However, today’s technology has advanced far beyond this. Investigators can now use DNA to trace distant familial connections, allowing law enforcement to build family trees and track down suspects through their relatives.

 

From CODIS to Public Databases

CODIS (Combined DNA Index System) has been the standard database used by law enforcement for matching DNA from known offenders. However, newer public databases like GEDmatch and FamilyTreeDNA have opened new doors for investigative genetic genealogy, enabling law enforcement to search a wider pool of DNA data to find familial matches.

  • CODIS: Focuses on known criminal offenders.
  • Public Databases: Allows access to broader, volunteer-submitted DNA profiles used in genealogy.

     

The Limitations of Direct DNA Matching

Direct DNA matching in databases like CODIS can only help solve crimes if the perpetrator is already in the system. In many cases, this lack of direct matches leaves investigations at a standstill. With investigative genetic genealogy, law enforcement can now search for familial DNA matches, uncovering relatives and leading to new avenues in unsolved cases.

 

Step-by-Step Guide to Educational Requirements for Investigative Genetic Genealogists

Becoming an investigative genetic genealogist requires a combination of foundational education in genetics and biology, specialized training in genealogy, and hands-on experience in the field. Here’s a step-by-step guide to the educational pathway for this exciting and evolving career.

 

Step 1: Earn a Bachelor’s Degree in Biology, Genetics, or a Related Field (4 Years)

To start your journey, you’ll need a strong foundation in science. A bachelor’s degree in biology, genetics, molecular biology, or forensic science is essential for developing the knowledge required for analyzing DNA and understanding its role in genealogy and crime solving.

 

Step 2: Obtain Specialized Training in Genetic Genealogy

Next, gaining expertise in genealogical tools and databases is crucial. Investigative genetic genealogists use public genealogical databases, such as GEDmatch or FamilyTreeDNA, to track family trees. Training in how to use these tools is essential for identifying suspects or victims.

  • Practical Experience: Seek internships or apprenticeships in forensic labs, genealogical research organizations, or law enforcement agencies to apply what you’ve learned.

     

Step 3: Consider a Master’s Degree in Genetics or Forensic Science

For advanced expertise, pursuing a master’s degree in genetics or forensic science is recommended. Degrees like our Master of Science in Human Genetics and Genomics (MSHGG) provide deeper knowledge in DNA analysis, preparing you for the complexities of applying genetic genealogy in criminal investigations.

  • Advanced Knowledge: Dive deeper into DNA technology, forensic science, and bioinformatics.
  • SCU’s MSHGG: Our program offers specialized knowledge in human genetics, perfect for students aiming for roles in genetic genealogy.

     

Step 4: Certifications for Investigative Genetic Genealogists

Obtaining certification can significantly boost your career prospects. Certifications, like those by the American Board of Criminalistics (ABC), not only enhance credibility but also open doors to more specialized positions in law enforcement or private genealogy firms.

 

The Rise of Forensic Genetic Genealogy: Jobs and Career Growth

The demand for forensic genetic genealogy is rising as more law enforcement agencies turn to this technique to solve cold cases. With the increased use of investigative genetic genealogy in criminal investigations, a new wave of job opportunities has emerged for those trained in both DNA analysis and genealogy.

 

Growth of IGG as a Specialized Field

As forensic genetic genealogy becomes more common in law enforcement, the field is rapidly expanding. Investigators now rely on skilled professionals who can navigate genealogical databases and combine that knowledge with DNA analysis to pinpoint suspects or identify victims. This has created a high demand for professionals trained in these dual specialties.

 

Career Paths for People Specializing in Genetic Genealogy

Specializing in forensic genetic genealogy opens a variety of career paths in both the public and private sectors:

  • Forensic Science Technician: Work in forensic labs analyzing DNA samples and building family trees to assist in criminal investigations.

     

  • Genetic Genealogist Consultant: Provide expertise to law enforcement agencies, working alongside detectives to trace suspects through family lines.

     

  • Private Investigator Specializing in Genealogy: Solve cases related to paternity, ancestry, or missing persons using both DNA and traditional genealogical research.

     

  • Genealogical Researcher for Forensic Labs: Partner with forensic scientists to apply genealogical methods to solve cold cases or unidentified human remains cases.

     

  • Law Enforcement DNA Specialist: Work directly with police departments to interpret DNA evidence and manage forensic genealogical databases.
