investigative genetic genealogy

Investigative genetic genealogy is a method used to solve crimes by analyzing DNA from crime scenes and comparing it with genetic information available in public databases, often derived from consumer DNA tests. By identifying relatives of the suspect through shared genetic traits, investigators can build a family tree and narrow down potential suspects. This approach has been instrumental in solving cold cases and unidentified remains, leveraging advancements in both genetic testing and genealogical research to bridge the gap between law enforcement and genetic science.
