As the investigation into Nancy Guthrie's disappearance enters its third week, a new development has drawn cautious attention: unidentified DNA discovered at her Tucson property.
The 84-year-old was reported missing on February 1, and authorities have classified the case as a suspected kidnapping. While investigators have pursued thousands of leads in recent days, officials confirmed that DNA recovered from the residence does not belong to Guthrie or those known to have been at the home. The material is now undergoing forensic analysis.
Several gloves found as far as 10 miles from the property are also being tested, according to law enforcement. Experts say advanced genetic genealogy - a method that has helped solve complex cases in recent years - could potentially provide a lead if the DNA does not match any existing criminal databases.
Meanwhile, a federal search warrant executed Friday night based on a lead concluded without arrests. Officials emphasized that such operations are part of standard investigative procedure as authorities work methodically through more than 30,000 tips received since the case began.
The FBI has described a masked individual seen in doorbell footage as a male approximately 5'9" to 5'10" tall with an average build, wearing dark clothing, black gloves, sneakers, and a black Ozark Trail Hiker backpack. No suspect has been publicly identified, and no charges have been announced.
Outside Guthrie's home, flowers, candles, and handwritten notes continue to accumulate. Neighbors and supporters have spoken openly about prayer and hope as they await answers.
As Week 3 begins, investigators remain focused on verified evidence - and the community remains steadfast in its hope that both careful forensic work and continued faith will lead to clarity in the days ahead.
Authorities urge anyone with credible information to contact 1-800-CALL-FBI, 88-CRIME, or the Pima County Sheriff's Department.
