Authorities investigating the disappearance of Nancy Guthrie in Tucson, Arizona in February 2026 are considering using genealogical DNA databases to help solve the case. This strategy, which involves comparing crime scene DNA to public genealogy records, has been successfully used in other high-profile cases. Notably, it aided in solving a series of murders in California and the fatal stabbings of college students in Idaho. The hope is that this method will provide leads and potential suspects in the Guthrie case, similar to its success in other investigations. The Pima County Sheriff's office is exploring this option as a potential avenue for advancing the investigation.
