FBI Intensifies DNA Analysis in Nancy Guthrie Case

Nancy Guthrie, the 84-year-old mother of NBC anchor Savannah Guthrie, vanished from her Tucson, Arizona, home in the early hours of February 1, prompting an intensified FBI investigation into what authorities describe as a likely abduction. The latest developments center on advanced DNA analysis of biological evidence recovered from the residence, including mixed genetic profiles and hair samples, which officials hope could yield a breakthrough in identifying a suspect.

Guthrie was last seen the evening of January 31, when her son-in-law dropped her off at her home in the Catalina Foothills around 9:50 p.m. Family members reported her missing the next morning after she failed to attend a scheduled church event. Investigators quickly determined the disappearance was suspicious, citing signs of forced entry and blood traces on the front porch. Surveillance footage from her doorbell camera, captured before it was disabled, showed a masked individual wearing a backpack approaching the door that morning.
