Desert Search for TV Host's Mother Intensifies

The search for 84-year-old Nancy Guthrie, mother of TV journalist Savannah Guthrie, continued for an 11th day across southern Arizona's desert landscape. Investigators are meticulously examining a black latex glove, discovered approximately 1.5 miles from her residence, for potential fingerprints and DNA samples. This evidence was found as law enforcement intensified their efforts to locate her. Authorities released video footage showing a masked intruder tampering with Guthrie's doorbell camera around the time she was taken. Advanced analytical techniques, potentially including AI, are being employed to enhance the images and identify facial features through the ski mask. Nancy Guthrie was last seen on January 31, and reported missing the following day. Traces of blood confirmed by DNA to be hers were found on her front porch. Two ransom notes have been delivered to news outlets, but no proof of life has emerged. The Pima County Sheriff's department, with FBI assistance, is following up on nearly 18,000 tips. A person of interest was briefly detained for questioning but later released. The investigation includes searching a location in Rio Rico, Arizona.
