A former FBI official has set out a stark theory about what may have happened to missing Arizona grandmother Nancy Guthrie, arguing on a US podcast this week that the answer to her disappearance in Tucson in February likely lies close to home and may involve a 'nightmarish' kidnap for ransom plot updated for the digital age. John Miller, a former FBI assistant director who now serves as CNN's chief law enforcement analyst, outlined his view nearly three months after Guthrie, 84, vanished from her home in Tucson's Catalina Foothills.
Nancy Guthrie disappeared in the early hours of 1 February from her residence in the affluent Tucson suburb. Authorities believe one or more people abducted the 84 year old, who is the mother of Today co host Savannah Guthrie. Despite extensive searches and intense media attention, she remains missing, and investigators have announced no arrests and named no suspect.
