Investigators turn to genetic genealogy to look for new leads in Nancy Guthrie case

Investigators searching for Nancy Guthrie, who was reported missing on February 1, are now turning to genetic genealogy and commercial DNA companies to find new leads in the case, with CBS News reporter Andres Gutierrez covering the latest developments in the ongoing investigation. This modern approach to cold cases involves comparing DNA evidence from the disappearance with genetic databases maintained by commercial genealogy services, potentially identifying distant relatives who could help establish a family tree and narrow down potential suspects or persons of interest. The technique has gained prominence in recent years due to its success in solving high-profile cases, including identifying the Golden State Killer through similar genetic genealogy methods. As the investigation into Guthrie's disappearance continues, authorities are exploring all available technological advancements to bring answers to her family and the community.
