New genetic sleuthing tool: Forensic genealogy

Recently, a new genetic sleuthing tool, forensic genealogy, was used to track down Joseph James DeAngelo suspected of being the “golden state killer” in the US. Since then, decades-old cold cases and some fresh crimes have been solved after genetic genealogy searches. While the description of the genomic analysis steps taken to find DeAngelo appeared to be the latest groundbreaking technology, investigators found genetic relatives could link even distant relatives accurately by locating identity-by-descent (IBD) segments after querying direct-to-customer (DTC) genomic database. In addition, in order to solve those cases, powerful triangulation techniques combined with some traditional genealogical methods in forensic genealogy were used to identify shared segments for validating the links, and the details were introduced. Forensic genealogy is the study of identification and kinship in legal contexts including finding family references for DNA identification, identifying missing persons, locating heirs for probate matters and more. The advantages for the forensic genetics community of introducing the new technology were discussed. Such as, improving the effectiveness of the existing DNA database to identify suspects in crime, reducing the impact of “ innocent ” individuals due to the inves-tigation and protect security of case information, and possessing higher success rates than with surname inference from the Y chromosome.
