DNA evidence found on gloves discovered about two miles from Nancy Guthrie’s home in Tucson, Arizona, did not produce any matches after investigators ran the profile through the FBI’s national DNA database, according to the Pima County Sheriff’s Department.
Authorities previously released surveillance images and video showing a masked person carrying a gun and wearing gloves on Guthrie’s front porch in the early hours of Feb. 1, the time investigators believe the 84-year-old was abducted. Days later, detectives recovered a pair of gloves along a roadside roughly two miles from her home that appeared consistent with those seen in the footage.
Investigators submitted the unknown male DNA profile to the Combined DNA Index System (CODIS). In an update posted on X, the sheriff’s department said the submission produced no matches.
Officials added that additional DNA evidence collected at the residence is still being analyzed.
As the investigation enters its third week, authorities continue searching for Guthrie, a mother of three, and the person or people responsible for her disappearance. Shortly after she vanished, several media outlets received alleged ransom notes tied to the case.

After releasing the surveillance material, the FBI’s Phoenix office described the suspect as a male approximately 5-foot-9 to 5-foot-10 with an average build. In the video, the person appears to be wearing a black 25-liter Ozark Trail Hiker Pack backpack, which investigators believe may have been purchased at Walmart. Pima County Sheriff Chris Nanos has said identifying the backpack is among the most promising leads so far.
Investigators have also said Guthrie’s doorbell camera was disconnected at 1:47 a.m., and then detected someone at the residence at 2:12 a.m. Sixteen minutes later, at 2:28 a.m., Guthrie’s pacemaker was disconnected from its cellphone app, authorities said.

Law enforcement sources told CBS News that investigators are using a “signal sniffer” in an effort to detect Bluetooth transmissions from Guthrie’s pacemaker.
In another update issued Feb. 13, the sheriff’s department said DNA “other than Nancy Guthrie’s and those in close contact to her” was collected from the property, and investigators are working to determine who it belongs to, without disclosing where it was found.
Savannah Guthrie, 54, has posted multiple videos on Instagram asking for her mother’s safe return. In one clip shared Feb. 15, she said the family remains hopeful.
Authorities are offering a $100,000 reward for information that leads to Guthrie’s recovery or an arrest.
