The investigation into 84-year-old Nancy Guthrie’s mysterious disappearance has led to yet another dead end. The DNA test results from a glove found two miles from Nancy Guthrie’s Catalina Foothills home, considered key evidence in the case, didn’t match any of the recorded profiles in CODIS, the FBI’s DNA database of known offenders.
Conventional methods have so far failed to track down a suspect in Nancy Guthrie’s kidnapping investigation. But authorities are in no mood to stop. They are now turning to an almost foolproof forensic tool that has solved some of America’s most chilling crimes: Investigative Genetic Genealogy (IGG). Will it be a reliable technique for a potential abduction case?
