Watch: Savannah Guthrie's Missing Mom Nancy Guthrie May Have Been Abducted, Police SayThe search for Nancy Guthrie continues. As authorities continue to investigate the disappearance of Savannah Guthrie's mother, Pima County Sheriff Chris Nanos confirmed they found DNA evidence at Nancy's home, which has been declared a crime scene. "We took some samples that we hope will have enough of a DNA profile," he told NBC News in a report shared on Today Feb. 3, "that will give us some identification as to what we're looking at." Nancy-who is also mom to kids Annie Guthrie and Camron Guthrie, in addition to Savannah-was last seen by family members around 9:30 p.m. on Saturday, Jan. 31. A concerned friend called Nancy's family, per Today, after the 84-year-old didn't show up for the church service the next morning. After her children searched Nancy's property for around an hour, they called authorities and reported her missing around noon on Sunday. In the time since, Sheriff Nanos has expressed police's concerns that the octogenarian-who he affirmed is not cognitively impaired-was likely abducted, as Nancy's physical health would have prevented her from leaving on her own.readSavannah Guthrie Shares Plea for "Beloved" Mom Nancy Guthrie After She Goes Missing"We know she didn't just walk out of there, that we know," he said during a Feb. 2 press conference, adding, "There are other things at the site, at the scene, that indicate there was a-she did not leave on her own."
