Pima County Sheriff Chris Nanos says he’s “still positive” the Nancy Guthrie case will be resolved as investigators continue to dig through evidence more than 25 weeks after her home invasion abduction in Tucson, Arizona.
“We have so much DNA to sort through,” Nanos said in an interview aired on “Today.”
Guthrie is the 84-year-old mother of one of the show’s co-hosts, Savannah Guthrie.

“We have so much, in terms of video evidence, to look at,” Nanos added. “So I’m still positive that we’re here to resolve this case.”
The sheriff’s remarks came hours after Savannah Guthrie released a new video plea to her mother’s abductors on Instagram, urging them to “make the right choice” and tell the family where to look for her.
A federal source told Fox News Monday that Guthrie consulted with law enforcement before releasing the video.

“It’s not clear why Savannah decided to release this message now, but it could be a response to a potential new line of communication,” Guthrie’s NBC colleague Erin McLaughlin reported Tuesday. “Experts say the language appears to be pointed at whoever committed the crime, though law enforcement have not provided any public updates in the investigation recently.”

Recent comments from FBI Director Kash Patel explained the technical process investigators used to recover cached recordings from Guthrie’s Nest doorbell camera that were facing imminent deletion in a back-end Google system. But Patel made the video public back on Feb. 10.

Nanos did not immediately respond to follow-up questions from Fox News Digital. Investigators had scoured the neighborhoods surrounding Guthrie’s home and her daughter Annie’s house nearby in search of video evidence that might show a suspect or suspect vehicle earlier in the investigation.
GOT A TIP?
“I wonder how many ‘leads’ they’ve covered,” said Jason Pack, a retired FBI supervisory agent who has been closely following the case. “There would be thousands…running down every device on the phone tower and their Wi-Fi router etc.”
The case would not be considered cold until all potential leads are exhausted without answers, experts have told Fox News Digital, and Pack said it doesn’t appear to have gone cold yet.

“If the sheriff says they have that much DNA and all of that video, then I don’t think you can call it cold until they’ve rectified those leads one way or the other,” he said.
There are likely terabytes worth of digital evidence in the case, he said.

“It’s a lot of pressure on criminals to keep such a hard secret, especially something so high profile,” Pack added. “You have the pressure from others involved of potentially being killed for talking or ratting them out. And the pressure of the over million-dollar reward on the other side.”
