Investigators have found surveillance footage of an armed, masked person at Nancy Guthrie's doorstep on the night she disappeared. Guthrie is the mother of “Today Show” host Savannah Guthrie. The FBI said the footage was retrieved from "backend servers" after initially believing it was lost. The camera was disconnected, and Guthrie didn't have a subscription to the camera company. This discovery raises questions about the persistence of digital content. Experts say footage can remain on cloud servers even if it seems deleted. Privacy concerns are also highlighted, as companies may share data with law enforcement without user consent.
