Surveillance footage of an armed suspect has been released by authorities investigating the disappearance of Savannah Guthrie's mother.
Nancy Guthrie, 84, went missing on January 31, and by February 2 the Pima County Sheriff's office had declared her disappearance a crime, and now they have released images and a video of a person with a hat over their face wearing gloves, with the figure appearing to have tampered with a camera at the victim's front door.
