Nearly three months after Nancy Guthrie vanished from her Tucson, Arizona home, the case has taken a dramatic twist that’s leaving investigators under pressure — and raising serious concerns about how crucial evidence was handled from the start.
At the center of the controversy is a key DNA sample that has finally landed in the hands of the FBI. But here’s the catch: the evidence isn’t new — and that’s exactly what has critics fired up.
Officials confirmed the FBI is now using advanced technology to analyze the sample in hopes of identifying a potential suspect. However, the timeline behind how that evidence got there is now under intense scrutiny.
According to authorities, the FBI actually requested the material more than two months ago. Instead of going straight to the bureau, the sample — reportedly a hair — was first sent to a private lab in Florida. After sitting there for roughly 11 weeks, it was only recently transferred to the FBI for testing.
That delay is now the biggest question mark hanging over the case.
Former FBI agent Jennifer Coffindaffer didn’t mince words when reacting to the development, openly questioning why the evidence wasn’t sent directly to the FBI in the first place.
She pointed out that the bureau’s so-called “advanced technology” isn’t anything new — meaning the capability to test the DNA was always there.
In other words, the delay may have been avoidable.
While Coffindaffer acknowledged that sending the sample to a private lab could have initially made sense — especially if investigators believed it would speed things up — her tone shifted sharply once it became clear the FBI had the necessary tools all along.
And that’s where emotions start running high.
Coffindaffer said the situation should leave Guthrie’s family deeply frustrated, arguing that the explanation behind the handling of the evidence simply doesn’t add up.
If the FBI had the best resources from day one, why wasn’t the sample sent there immediately?
That question is now echoing far beyond the investigation.
Meanwhile, the Pima County Sheriff’s Department is pushing back on the growing backlash, insisting this latest move doesn’t signal any major shift in the case. Officials maintain they’ve been working alongside the FBI from the beginning and emphasize that the DNA testing process is still ongoing.
But that hasn’t quieted the noise.
With no clear answers yet and the clock ticking toward the three-month mark since Guthrie disappeared, the case is entering a tense new phase — one filled with uncertainty, mounting criticism, and a family still waiting for answers.
And according to experts, they may be waiting a while longer. Even with the FBI now involved, DNA results could take months to process, stretching out an already agonizing investigation.
For now, one thing is clear: what was supposed to be a breakthrough has instead opened the door to even more questions.
