Former FBI special agent Jennifer Coffindaffer has said the family of missing Arizona grandmother Nancy Guthrie, includingTodayshow co-host Savannah Guthrie, have every reason to be 'upset' with how DNA evidence in the case has been handled, after a crucial hair sample was sent to a private Florida lab before reaching the FBI's own facility in Quantico.
84-year-old Nancy Guthrie vanished from her Tucson-area home in Pima County earlier this year, triggering a sprawling search that quickly drew national attention because of her daughter Savannah's public profile. Detectives from the Pima County Sheriff's Department recovered a hair without a root inside Nancy's home and treated it as potential forensic gold. That single strand is now at the heart of a dispute over whether investigators made a misstep that may have slowed progress in an already baffling case.
Coffindaffer, who has become a familiar voice in high-profile investigations, initially backed the sheriff's decision to send therootless hairto a long-standing private partner lab in Florida. On her true crime podcast, she said the logic at the time seemed sound, because the lab already had established DNA profiles tied to the case and was poised to move quickly in what everyone understood was a race against time.
Her view shifted sharply when it emerged that the Florida lab had recently shipped a DNA sample from the Guthrie case to the FBI for 'advanced technology' testing. That disclosure raised a blunt question in her mind: if the FBI's Quantico lab always had the more powerful tools, why was the hair not sent there first?
Coffindaffer's criticism is not abstract. She is fixated on what she describes as an unnecessary delay of '70-some-odd days' before the FBI's most sophisticated capabilities were brought to bear on the DNA evidence.
'The fact that they're saying the FBI has this advanced technology, they would've always had it,' she said, arguing that federal analysts at Quantico have long been able to work with challenging samples such as rootless hair. 'So that should really irk everyone that the sample didn't go there because they would have always had the advanced technology and expertise.'
In her view, that gap matters. Even if the FBI ultimately draws the same scientific conclusions the private lab did, she believes the case lost momentum at a point when public tips, digital trails and suspect movements might still have been fresher.
Coffindaffer went further, explicitly tying her frustration to the family's experience.
'Knowing that they had that technology, that should really have the Guthrie family, and anybody who cares about justice for Nancy Guthrie, upset, because that is not tracking at all,' she said. Coming from a former federal agent, that is more than routine second-guessing; it is a pointed suggestion that the sheriff's office chose familiarity over the best-available option.
