Twelve days after 84-year-old Nancy Guthrie was taken from her Tucson home, investigators say they are still working around the clock — but no suspect or person of interest has been taken into custody.
In the latest development, authorities confirmed that a pair of black gloves discovered during the search has been submitted for DNA analysis. The gloves were located as law enforcement teams continued combing through the Catalina foothills and surrounding areas, hoping to uncover any trace evidence that could move the case forward.
The discovery comes amid an intense and expanding investigation that has gripped the Tucson community.
Surveillance footage released earlier this week from Guthrie’s home showed a masked individual near the property. Since those images became public, the Pima County Sheriff’s Department says it has received an overwhelming surge of tips — more than 18,000 calls since Guthrie was reported missing on February 1, including 4,000 tips after the video was released.
Investigators have also asked neighbors with Ring and Nest doorbell cameras to review and submit footage from two key windows of time: January 11 between 9:00 p.m. and midnight, and January 31 between 9:30 and 11:00 a.m., the morning Guthrie disappeared. The earlier January date — weeks before she went missing — has raised questions about whether the suspect may have been surveying the area.
According to law enforcement officials, every tip received through the FBI’s national hotline is logged, numbered, and entered into a tracking system for evaluation. Analysts assess which leads require immediate attention and which may provide broader context. High-priority tips are forwarded to detectives or FBI agents for rapid follow-up.
Authorities are also reviewing retail records connected to items seen in the surveillance footage, including a distinctive backpack. Investigators may cross-reference purchase histories, surveillance video from stores, and financial transaction data to identify potential matches.
One man was detained earlier this week after a property near the Mexican border was searched. He was later released, and officials emphasized that no arrest has been made in connection to Guthrie’s disappearance.
Meanwhile, the Tucson community has rallied around Guthrie’s family. Yellow flowers — a symbol of hope — now sit outside her home. At a local NBC affiliate where a family member once worked, a banner bearing the message “Bring Her Home” hangs prominently, with residents encouraged to sign it in support.
Neighbors say the case has deeply unsettled the area. Some have installed new security systems and activated alarms for the first time in years.
As for the black gloves, investigators are working to determine whether they are connected to the suspect, an unrelated passerby, or even part of earlier search efforts. DNA testing could reveal whether the gloves match profiles in national criminal databases or help identify an unknown individual.
For now, authorities say the investigation remains active and urgent. With thousands of tips still being sorted and forensic results pending, law enforcement officials remain hopeful that one crucial piece of evidence will bring clarity — and answers — in the days ahead.
