Investigative genetic genealogy is a rapidly growing field of forensics that allows detectives to solve cold cases using genetic information. This powerful tool combines DNA found at the crime scene with direct-to-consumer DNA tests that have been published on public platforms. In cases where traditional investigative techniques run into roadblocks, forensic genealogy services can be employed to uncover new leads for unresolved cases.
How Does Forensic Genealogy Work?
Forensic genealogy uses crime scene DNA evidence and compares it with publicly available DNA information available using tools such as GEDMatch Comparison. Many people post direct-to-consumer DNA results online on public forums in an effort to learn more about their ancestry or to find long-lost relatives. Investigators can use this information to match the DNA found at the crime scene and uncover potential suspects.
The technique relies on the principle that everyone was related at some point. The degree to which two people’s DNA matches can help uncover exactly how close the relationship is and help narrow down the pool of suspects. Suppose a genealogist can find a cousin of a suspect who has left behind DNA evidence at the crime scene. In that case, investigators can reverse-engineer the family tree to uncover more information about the suspect.
