Importance of forensic genealogists in cold case investigations

Forensic genealogists play a crucial role in cold case investigations by utilizing their expertise in genetic genealogy to provide leads and identify potential suspects. In many cold cases, traditional investigative techniques have failed to produce any significant breakthroughs. However, with the advent of forensic genealogy, previously unsolvable cases are being reopened and fresh investigative leads are being generated, offering hope for justice to the victims and their families.

Forensic investigative genetic genealogy techniques and tools

Use of DNA tests in forensic genealogy

DNA tests are central to the practice of forensic genealogy. DNA samples collected from crime scenes or from unidentified individuals are subjected to forensic DNA analysis to obtain genetic information. This information is cross-referenced with genetic databases, such as those maintained by law enforcement agencies and genetic genealogy service providers, to identify potential matches and establish familial relationships.

Building family trees for investigative purposes

A key technique used by professional genealogists is the construction of comprehensive family trees. By analyzing genetic data and genealogical records, they trace lineages, identify ancestors, and establish connections between individuals. These family trees serve as a roadmap in identifying potential suspects, narrowing down leads, and assisting in investigations.

Integration of traditional genealogy with forensic genealogy

Forensic genealogy relies on the integration of traditional genealogical research methods with modern forensic techniques. While traditional genealogy focuses on reconstructing family histories using paper trails and historical documents, forensic genealogy combines this information with DNA analysis to enhance the accuracy and efficiency of investigative processes. This integration creates a powerful tool in solving cold cases and identifying unknown individuals.

Applications of forensic genealogy
