"Guthrie, the 84-year-old mother of Today show co-host Savannah Guthrie, was last seen on Jan. 31. So far, a key tool the Combined DNA Index System (CODIS), a federal database of genetic records mainly taken from people suspected or convicted of crimes has not returned a match for samples that have been tested, according to the Pima County Sheriff's Department."
""Investigators are currently looking into additional investigative genetic genealogy options for DNA evidence to check for matches," the sheriff's department said on Tuesday. An important option is forensic investigative genetic genealogy (FIGG), which incorporates public genealogy websites with DNA analysis. It has cracked high-profile cold cases such as the Golden State Killer attacks prompting the National District Attorneys Association to proclaim in late 2023 that FIGG was ushering in a "new era in crime solving.""
DNA was recovered in and around Nancy Guthrie's Tucson home after she was last seen Jan. 31. CODIS searches produced no matches for tested samples. Pima County investigators are exploring additional DNA methods, including forensic investigative genetic genealogy (FIGG), which uses public genealogy websites combined with DNA analysis. FIGG has solved high-profile cold cases like the Golden State Killer and was credited with helping solve the Bryan Kohberger case, demonstrating FIGG's use in active investigations. Authorities are evaluating FIGG and other investigative genetic genealogy options to check for matches as they continue the search.
