Nancy Guthrie was reported missing on February 1, 2026.
Nancy Guthrie Investigators Say Arrest Could Be Near
One hundred days after Nancy Guthrie disappeared from her Arizona home, investigators say that they believe the case will eventually lead to an arrest as forensic testing and the analysis of digital evidence continues.
Pima County Sheriff Chris Nano spoke to 13 News in the first substantial update in weeks. He said that the disappearance of Savannah Guthrie's mother is still being actively investigated even with limited information.

In a new interview, Nanos confirmed that authorities are intentionally withholding information from the public while forensic and digital evidence are being processed.
“Yes, absolutely there are,” Nanos said when asked if investigators were keeping details private.
“But it’s not done because we got to keep it secret,” he continued. “It’s done because we got to protect our case.”
Nanos explained that investigators are still working through both biological and digital evidence, including DNA that was found at Guthrie's home. Among them, would be the sample of blood found outside that has been sent away for testing.
"Whether it's on the digital end or the biological end, DNA." he said.
Authorities have sent away evidence to a lab so that they can separate and identify multiple DNA samples that were collected during the investigation. The sheriff warned that this process could take time.
“It moves at a snail’s pace, I guess for some,” he said. “But for my investigative team, and for me, we look at this as, no, this is doing exactly what we need it to do.”
Investigators say case is ‘far from cold’
Nancy Guthrie's DNA samples could take months.
Official updates have been far and few between in recent weeks, with much of the attention going to reported tension between the FBI and the Pima County Sheriff's Department.
Both Kash Patel and Nanos have made statements about the Nancy Guthrie case, with Patel stating that the local authorities delayed getting the FBI involved. Nanos disputed the FBI chief's version of events, pointing out that on the same day that Guthrie was reported missing, an FBI agent was on the scene.
The sheriff's office was under pressure after they sent evidence to a private lab in Florida instead of giving it directly to federal investigators.
Despite those questions, Nanos insists that the FBI is deeply involved in the investigation.
“They are working hard to get this resolved, and I think every day they get closer,” Nanos said.
“Day one, the FBI was involved in this case,” he added. “And they continue to be involved in this case. Every single day.”

Nanos also said he believes investigators will eventually identify and arrest a suspect.
“I believe, at some point in time, we will make an arrest on this case,” he said. “And whoever that individual is, that individual will have a right to a fair and impartial trial.”
Even as the evidence is still being processed, authorities say that they need help from the public.
"We need you to call us," Nanos stated. "We know somebody out there knows what happened here."
He added, "There’s way too much work to be done, that is ongoing, with some of the physical evidence we have,” Nanos said. “And we’re not going to give up on it just because it’s been 100 days.”
