Investigation Into Alleged Abduction of Nancy Guthrie Stalls as DNA Work and Tips Drag On

Forty-five days after 84-year-old Nancy Guthrie was allegedly abducted from her Tucson home on Feb. 1, investigators say newly reviewed surveillance footage from additional cameras on the property has yielded no suspicious activity and no fresh images of the suspect beyond an FBI doorbell video released Feb. 10. The cameras, covering the driveway, garage and back of the house, showed only family members, landscapers and pool workers in the weeks before the kidnapping, underscoring what a retired FBI supervisory special agent describes as a 'lack of meaningful leads.' DNA recovered from the scene is now being processed using forensic genetic genealogy, a tool that has cracked other major cases but can take considerable time as investigators vet multiple potential relatives. Authorities have logged more than 1,500 tips since the Guthrie family offered a $1 million reward, yet it has been nearly three weeks since the family last publicly appealed for help and over a month since law enforcement held a press conference. Experts warn that as time passes it becomes harder to keep such investigations active and generate new leads, even in a high-profile case tied to "Today" co-host Savannah Guthrie’s mother, raising questions about how long intensive federal and local resources can be sustained without breakthroughs.
