Summary
The investigation into the disappearance of Nancy Guthrie uses genetic genealogy to try to find a suspect. Challenges arise because key DNA evidence cannot be uploaded to large databases due to privacy policies, limiting search options to smaller databases. This method requires a viable DNA sample from the suspect to be effective.
