Authorities are seemingly intensifying their search for Savannah Guthrie's mother, Nancy Guthrie, who has been missing for nearly two weeks. Multiple SWAT, forensics officers and law enforcement cars were spotted in Nancy's Tucson, Arizona, neighborhood on Friday, February 13, according to CNN and NewsNation. CNN reported that police officers converged on two locations without making any arrests, but did question a man about his apparent involvement. The individual, who was reportedly cooperative, was ultimately released.
