Investigation Continues in Nancy Guthrie's Disappearance; Family Members Questioned

Nancy Guthrie, mother of NBC's Savannah Guthrie, has been missing since January 31 from her Tucson, Arizona residence, which authorities are treating as a crime scene amid concerns of abduction. Annie Guthrie, Nancy's daughter, was the last known person to see her, having returned her home after dinner. Annie's husband, Tommaso Cioni, a local teacher, has been contacted by police but is not officially a suspect. The FBI is involved, and investigators continue to explore leads, including an alleged ransom note, while the family remains cooperative.
