The search for 84-year-old Nancy Guthrie has entered a more troubling phase as investigators examine newly released surveillance footage from outside her Tucson home. Nancy disappeared on February 1, and blood discovered inside the residence quickly escalated concerns that something violent may have occurred. Nearly two weeks into the investigation, the FBI shared Nest doorbell video that offers the first public glimpse of a masked figure lingering near her front door in the early morning hours, raising fresh questions about what may have happened that night.

In the footage, a lone person dressed in light-colored clothing approaches the house wearing gloves and a balaclava. The individual carries a backpack and what appears to be a firearm. At one point, the person seems to tamper with the doorbell camera, suggesting an attempt to avoid identification. The deliberate movements and concealment have fueled fears that the visit was planned rather than accidental or random.
