Nancy Guthrie, the 84-year-old mother of Savannah Guthrie, has been missing since February 1, 2023, after reportedly being taken from her home in Catalina Foothills, Arizona. The investigation, led by the Pima County Sheriff's Office with assistance from the FBI, has yet to identify any suspects. Self-styled investigator Jonathan Lee Riches has made controversial claims, stating that the home of Nancy's daughter, Annie Guthrie, and her husband, Tommaso Cioni, was a 'crime scene.' Riches alleges that Annie sought a loan from Nancy prior to her disappearance and that a survey was conducted at their home the night before Nancy went missing. However, Sheriff Chris Nanos has publicly cleared Annie and Tommaso of any suspicion. Despite this, interest in the couple has remained high, particularly since they were among the last to see Nancy before her disappearance. Savannah Guthrie has defended her sister and brother-in-law, emphasizing their love for their mother. The investigation is ongoing, and authorities are cautious about releasing further details.
