Investigators Seek New DNA Analysis Leads in Nancy Guthrie Disappearance

Investigators in Arizona are exploring additional forensic DNA analysis options in the disappearance of Nancy Guthrie, nearly nine months after the 84-year-old woman went missing from her Tucson-area home.

Pima County Sheriff Chris Nanos confirmed that members of the investigation task force traveled to Florida earlier in October to meet laboratory scientists and discuss potential approaches to advancing the case.

The development was reported on October 31, 2026, following a statement issued by the sheriff on Friday evening.

According to authorities, investigators are continuing to work with forensic laboratories to assess whether further DNA analysis could produce useful investigative leads.

However, officials have not disclosed the type of biological evidence under examination, the laboratories involved or the specific forensic techniques being considered.

It also remains unclear whether the Florida consultations have resulted in any new findings.

Guthrie, the mother of American television journalist Savannah Guthrie, was reported missing on February 1 after failing to attend church. Her family last saw her at her home on the evening of January 31.

No arrests have been announced.

The investigation highlights the role of forensic genetics in unresolved missing-person cases, where additional laboratory examination may help investigators reassess biological evidence.

Nevertheless, DNA findings require careful interpretation. The detection of a genetic profile does not independently establish when biological material was deposited or whether its contributor was involved in a crime.

Authorities continue to request information from the public as the investigation remains ongoing.
