The Pima County Sheriff’s Department has provided a new update on the investigation into the disappearance of Nancy Guthrie, confirming that DNA analysis remains a key focus of the ongoing probe. Investigators recently traveled to Florida to consult with lab scientists about advancing forensic techniques in the case, according to a statement posted on X (formerly Twitter) on Friday evening.
Authorities emphasize that no tip is too small and continue to urge the public to come forward with any information. The task force, which includes federal and local partners, is actively pursuing leads while working to refine investigative methods. Guthrie, 84, was last seen at her home in Tucson, Arizona, on January 31, and her disappearance has drawn national attention.
Investigators believe Guthrie was taken against her will, as drops of blood were found outside her front door. A masked individual was captured on her Ring doorbell camera the night she vanished, tampering with the device. Authorities have not yet identified a suspect or person of interest in the case.
The sheriff’s department confirmed in the days following Guthrie’s disappearance that she did not leave voluntarily. "She did not leave on her own. We know that," Pima County Sheriff Chris Nanos stated during a prior briefing. While no suspect has been named, authorities have reviewed multiple ransom notes linked to the case, though one was deemed "not credible" last month.
Guthrie is the mother of NBC journalist Savannah Guthrie. Her family has publicly appealed for information, sharing videos and social media posts in hopes of identifying the individual responsible. The investigation remains active, with authorities encouraging anyone with details to contact 88-CRIME or 1-800-CALL-FBI.
This is a developing story, and further updates will be provided as new information emerges.
