A masked person with a handgun holster was caught on camera outside Nancy Guthrie's front door the night she disappeared, images released Tuesday by the FBI show, offering the first major break in a case that has gripped the nation for more than a week. The person wearing a backpack and a ski mask can be seen in one of the videos tilting their head down and away from a doorbell camera while nearing an archway at the home of the mother of "Today" show host Savannah Guthrie. The footage shows the person holding a flashlight in their mouth and trying to cover the camera with a gloved hand and part of a plant ripped from Nancy Guthrie's yard. The videos — less than a combined minute in length — gave investigators and the public their first glimpse of who was outside Nancy Guthrie's home just outside Tucson, but the images did not show what happened to her or help determine whether the 84-year-old is still alive. FBI Director Kash Patel said the "armed individual" appeared to "have tampered with the camera." It was not entirely clear whether there was a gun in the holster. The videos were pulled from data on "back-end systems" after investigators spent days trying to find lost, corrupted or inaccessible images, Patel said. "This will get the phone ringing for lots of potential leads," said former FBI agent Katherine Schweit. "Even when you have a person who appears to be completely covered, they're really not. You can see their girth, the shape of their face, potentially their eyes or mouth. You can see a gait that people around that person may recognize immediately." Investigators have said for more than a week that they believe Nancy Guthrie was taken against her will. She was last seen at home Jan. 31 and reported missing the next day. DNA... Read More
