New evidence surfaces in Nancy Guthrie kidnapping probe

Three weeks after Nancy Guthrie vanished from her Tucson home, CNN outlines a visual guide to the evidence: surveillance footage shows a masked man at the door attempting to block Guthrie’s Nest camera, investigators recovered a backpack and gloves, DNA found on Guthrie’s property has no matches in CODIS, and ransom notes are being scrutinized with genetic genealogy as a potential next step. A private donor has added a $100,000 reward and authorities have boosted the reward to $100,000, bringing total offers to $200,000 as investigators pursue tips and leads.
