Digital forensics specialists say Nancy Guthrie's disappearance in Tucson, Arizona, could yet be cracked by the kind of phone and network data many people barely notice, as police continue searching for the 84-year-old mother of TV host Savannah Guthrie more than three weeks after she vanished from her home on 1 February. Officials have still offered no confirmation of a suspect and no public indication of where Guthrie might be.
The search has continued under rising pressure, with authorities introducing a no-parking policy around her residence on 26 February, citing traffic congestion, while the family and investigators have leaned on a $1 million reward in the hope that someone, somewhere, decides to talk. Hope and evidence, as experts keep noting, are not the same thing.
