The disappearance of the 84-year-old Guthrie, mother of Today Show host Savannah Guthrie, set off a media firestorm that has been going strong for 100 days now.
In the days following her disappearance, the roads surrounding her home were packed.
100 days later, and it’s silent, with the memorial being the only reminder of what happened, but Pima County Sheriff Chris Nanos said in an interview with 13 News, their work continues.

“They are working hard to get this resolved, and I think every day they get closer,” Nanos said.
The sheriff was referring not just to his detectives working this investigation, but also to the agents at the FBI.
“Day one, the FBI was involved in this case,” he said. “And they continue to be involved in this case. Every single day.”
Nanos said they’re also receiving help from Arizona DPS and a handful of labs across the country.
“We continue to work with our labs,” he said. “Whether it’s on the digital end or the biological end, DNA.”
When it comes to DNA, Nanos said the labs are having to separate all of the different DNA that was found inside Guthrie’s house, and then work to identify who it belongs to.
And that takes time.
“It moves at a snail’s pace, I guess for some,” Nanos 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.”
Because they want to ensure they’re doing it right.
Not only to avoid arresting the wrong person, but to ensure they are able to properly prosecute whoever was involved.

“I believe, at some point in time, we will make an arrest on this case,” Nanos said. “And whoever that individual is, that individual will have a right to a fair and impartial trial.”
He said they’ll also be able to take the DNA found, use it to figure out information about the individual, and then hopefully connect that to the countless digital pieces of evidence they’ve collected and catalogued.
And that’s why Nanos said he absolutely does not see this case as cold.
“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.”
13 News reporter Renee Romo asked Nanos if there was information they were withholding from the public.
“Yes, absolutely there are. But it’s not done because we got a keep it secret,” he said. “It’s done because we got to protect our case.”
And while the PCSD and FBI have received tens of thousands of tips, both agencies urge you to call if you saw, heard, or remember anything.
“We need you to call us,” Nanos said. “We, we know somebody out there knows what happened here.”
