Inconclusive Hair Sample Hampers Search for Missing Mother Nancy Guthrie
The investigation into the disappearance of Nancy Guthrie, mother of 'Today' show co-host Savannah Guthrie, has hit a roadblock as a hair sample found at her Tucson, Arizona home returned inconclusive results. Pima County Sheriff Chris Nanos announced that the hair sample did not lead to any suspects. Despite the setback, the investigation continues with other DNA evidence being analyzed. Nancy Guthrie was last seen on January 31, and investigators believe she was abducted. Surveillance footage captured a suspect at her door, but no new video evidence has been found. The sheriff remains optimistic about solving the case, citing ongoing efforts by multiple labs and the FBI.
