The search for Nancy Guthrie, the 84-year-old mother of "Today" show host Savannah Guthrie, has entered its fourth week with no suspects, no matches in federal databases, and a sheriff now conceding that DNA analysis from the crime scene could take "weeks, months or maybe a year."
Pima County Sheriff Chris Nanos revealed last week that a private Florida lab handling DNA evidence collected from Guthrie's Tucson home has hit a wall. The lab has been unable to match a sample to any convicted criminals or suspects in the FBI's CODIS database, the NY Post reported. A glove found two miles from the house also produced no matches when analyzed.
No one has been named as a suspect. No list of names exists, according to the sheriff himself. And no one can explain why Nanos chose a private lab in Florida over the FBI's own facilities or Arizona's state Scientific Analysis Bureau.
Nanos acknowledged the investigation's delays in an interview with NBC News on Friday, framing the DNA setbacks as a technology problem rather than a decision-making one:
"Our lab tells us that there's challenges with it, and we understand those challenges."
He then offered what might be the most unusual expression of optimism in a missing-persons case in recent memory:
"But our lab also knows that the technology is moving so fast and in such a frenzy that they think some of this stuff will resolve itself just in a matter of weeks, months or maybe a year, to allow them to do better with, say, a mixture of that kind of thing."
That is not a timeline. That is a hope that science will eventually catch up to whatever is wrong with the evidence his chosen lab is struggling to process. An 84-year-old woman is missing, and the lead law enforcement official is telling the public that the DNA samples might sort themselves out if everyone just waits long enough.
The decision to route forensic evidence through a private Florida lab instead of the FBI raises obvious questions that Nanos has not addressed. The FBI is already involved in the case, continuing to analyze cellphone data, video, and interviews. Their CODIS database is the standard tool for matching crime-scene DNA to known offenders. Yet the physical evidence went to a private outfit in another state.
Nanos has faced accusations of letting his ego dictate the investigation. Whether or not that characterization is fair, the results speak for themselves:
Nanos insists the investigation is moving forward. He described the progress as "growing" and said his team is getting closer to identifying items visible in the surveillance footage, including shoes, pants, and a shirt or jacket worn by the suspect.
That is where things stand after a month. They are trying to identify clothing.
There is a particular kind of failure that occurs when local officials treat a high-profile case as their territory rather than their responsibility. The FBI has the labs. The FBI has the database. The FBI has the resources to process complex DNA mixtures that apparently baffle the private lab Nanos selected. And yet the sheriff chose a different path, one that has produced zero matches and an indefinite timeline.
Multiple local businesses have reportedly claimed they were shown lists of names and pictures by the FBI, which complicates Nanos's assertion that officers have no suspects or names to work from. Either the FBI is running a parallel investigation with different information, or the sheriff's public statements are not painting the full picture. Neither possibility is reassuring.
Nanos struck a resolute tone in his NBC interview:
"We're not quitting. We'll find her."
No one doubts the sincerity. What they doubt is the strategy. When you have the full weight of federal forensic infrastructure available, and you opt for a private lab that can't deliver results in any foreseeable timeframe, the question is no longer about commitment. It is about judgment.
The FBI continues its own analysis of cellphone data, video, and interviews. Whether that parallel track produces leads faster than the Florida lab processes DNA remains to be seen. The sheriff says he wants answers as badly as anyone. He told NBC he pushes his team constantly.
"It's never fast enough for the sheriff. I want it like you, 'Come on, guys, let's go, let's go, let's find her.'"
Urgency without competence is just noise. Nancy Guthrie's family does not need reassurance that the sheriff is impatient. They need results. Four weeks in, the evidence sits in a lab a continent away from Tucson, unmatched and unresolved, while the man responsible for that decision asks the public to trust that time will fix what his choices broke.
