Investigators believe that Nancy Guthrie, who was aged 84 when she was last seen on 31 January, was taken against her will from her home, but they have not shared a possible motive or arrested a suspect. On Saturday morning Savannah Guthrie wrote on Instagram: "We have lived every moment, every breath, and every heartbeat in agony and despair." The ransom notes were addressed to Savannah Guthrie and the Guthrie family, and sent to a local TV station in Tucson, Arizona, in the days after Nancy Guthrie disappeared, according to the sheriff. The first note, which was received on 2 February, began: "Hello Savannah, we have your mother Nancy. She will be held for ransom and once payment is received she will be released unharmed.
