The mysterious masked figure who was seen trying to obscure Nancy Guthrie's Nest doorbell camera on the night of her abduction is said to have visited the house before. Federal investigators released eerie footage of the unidentified suspect standing at Guthrie's front door, but CNN reported the images of him carrying a backpack and with a gun holster were then taken on a different day. Authorities said 'any suggestion that the photographs were taken on different days is purely speculative.' #news #usa #kidnapping #crime
