The FBI has released surveillance images in the investigation into the kidnapping of Nancy Guthrie, showing a masked, armed figure outside her Tucson home in the early hours of her disappearance. The photos, shared publicly as the search enters its 11th day, capture a suspect wearing a balaclava, gloves, a jacket, and a backpack while appearing to tamper with a video doorbell camera. Officials say the images may provide key clues as authorities continue working to identify the attacker.
