New developments have emerged in the ongoing investigation into the disappearance of 84-year-old Nancy Guthrie, as authorities continue to examine new evidence and follow incoming tips. Recently released surveillance footage from outside her Tucson home has drawn public attention, providing investigators with new material to analyze while the search effort continues.

The images, recovered through technical reconstruction of security system data, show an unidentified masked individual near the residence on the morning Nancy Guthrie was reported missing. Officials say the footage was difficult to retrieve because certain recordings were not automatically saved, requiring specialists to recover remaining data from backend systems. Authorities have not confirmed the identity of the person shown.

Former law enforcement experts reviewing the footage publicly noted that some actions visible in the video may suggest inexperience, particularly the way the individual handled equipment and approached the security camera. Analysts also observed attempts to block the camera using nearby objects, rather than bringing tools typically used to disable surveillance devices, which some experts say could indicate limited preparation.

Meanwhile, investigators continue to evaluate multiple leads and persons of interest. One individual questioned earlier this week was released without charges. Authorities emphasize that the investigation remains active and encourage anyone with useful information to come forward, while federal officials continue offering a reward for tips that could help locate Nancy Guthrie and clarify what occurred.
