Nancy Guthrie's disappearance in Tucson, Arizona, on 31 January has now stretched into its fifth month with no arrest, and a former detective from the Laci Peterson murder investigation believes a simple digital misstep may yet expose her abductor if investigators carry out a 'reverse search' of online data linked to her address. The case has drawn national attention because Guthrie is the mother of 'Today' anchor Savannah Guthrie, but there has still been no clear breakthrough.
Guthrie was last seen at her home on the evening of 31 January and was reported missing the following day after failing to appear at a church service. The Pima County Sheriff's Department, with support from the FBI, has carried out an extensive search, reviewed neighbourhood footage, collected material from home security systems and sent evidence to federal laboratories. Four months on, there is still no named suspect, no arrest and no confirmed trace of the pensioner's movements after that night.
