The search for 84-year-old Nancy Guthrie, who disappeared from her Arizona home in early February, has entered its seventh week as investigators pursue new leads in what authorities believe may be a targeted abduction.

Guthrie was last seen at her residence in the Catalina Foothills near Tucson. Surveillance footage showed a masked, armed individual approaching the property shortly before she is believed to have been taken. Authorities have not identified a suspect.

Federal investigators are now examining a nearby vacant home as part of the ongoing case. According to reporting from the scene, agents have been asking questions about a neighboring property that was vacated shortly before Guthrie’s disappearance, though officials have not confirmed any direct connection.

Law enforcement sources say revisiting locations and leads is a routine part of prolonged investigations, especially as new information emerges. Former Pima County Sheriff’s officials note that vacant properties can sometimes serve as staging areas, allowing suspects to observe neighborhoods or operate without drawing attention.

Authorities have spent weeks canvassing the area, reviewing surveillance footage, and interviewing residents, but Guthrie’s whereabouts remain unknown.

The case has drawn national attention due to her connection to television host Savannah Guthrie. While the family has remained largely out of the public eye, the investigation continues as officials work to determine what happened and locate the missing woman.
