The disappearance of Nancy Guthrie continues to develop as investigators focus on new details in the case. Authorities say they are now closely examining two key dates before she vanished, hoping they may reveal what led up to the incident.

Nancy Guthrie, 84, was last seen at her home in Tucson, Arizona, on January 31. Evidence found at the scene, including blood on the porch, led investigators to believe she was taken against her will.

In the latest update, FBI agents have been going door to door in the neighborhood, asking residents for surveillance footage from January 11 and January 24. Officials have not yet explained why these dates are important.

Authorities have also recovered additional images from cameras around the property. Some of the footage shows unidentified individuals near the home before the disappearance.

Despite weeks of searching, no arrests have been made. Investigators say they believe the case was targeted, but they are still withholding details about a possible motive.

The FBI and local authorities continue to work together, analyzing DNA evidence, surveillance videos, and tips from the public. A reward has been offered for information that could lead to answers.

Nancy Guthrie’s family remains hopeful, though the uncertainty has been difficult. Officials say the investigation is still active and new developments could emerge at any time.
