ICYMI: How A Family Tree And Genealogy Led Authorities To Kohberger

Beyond The Horizon

Genealogy is used in solving crimes by tracing the lineage of DNA found at crime scenes to identify possible suspects and then confirming or excluding them through further DNA testing. This method, called genetic genealogy, involves comparing the crime scene DNA profile to publicly available genetic genealogy databases, and then using traditional genealogical research to identify potential relatives of the person whose DNA was found at the crime scene. The goal is to find a close relative of the person whose DNA was found, and then work backwards to identify the person responsible for the crime. This approach has been successfully used to solve a number of cold cases, particularly in the United States.
In this episode, we see how this applies to the Bryan Kohberger arrest and how a new trend using genealogy to solve current cases is beginning to emerge.
