More than amonth into the searchforSavannah Guthrie's missing mom,Nancy Guthrie, the sheriff leading the investigation believes they are "definitely closer" to identifying and locating a suspect or suspects.
Pima CountySheriff Chris Nanosspoke with NBC's Liz Kreutz in a new interview, which aired on theTodayshow on Tuesday, March 3. When asked by Kreutz whether investigators are "any closer to finding a suspect or suspects," Nanos replied, "I think that investigators are definitely closer. We've got a lot of intel, a lot of leads, but now it's time to just go to work."
Nancy, 84, was taken from her Tucson, Ariz., home on Feb. 1, and since that time, authorities have not been able to successfully identify a single suspect.
Last month, doorbell camera footage was released of a masked, armed man attempting to enter Nancy's residence, shortly before her pacemaker was disconnected from its track device.
Nancy's neighbors have also submitted numerous doorbell camera videos in the area, including a video first shared by Fox News Digital last week of a car speeding down the road 2.5 miles from Nancy's home around the time of her abduction.
"We're aware of it and we're looking into it, just like any other piece of evidence," Nanos said of the clip, adding that investigators have not been able to identify the vehicle.
"We're looking at that vehicle as well as hundreds of thousands of other vehicles that were out driving at that time of day," he added.
Police are exhausting every pathway, including second-guessing their original claim that the intruder'sbackpack came from Walmart.
"We're now learned that maybe it wasn't purchased out of Walmart," Nanos said. "That backpack is new, it's exclusive to Walmart, but who's to say I didn't buy it and put it on eBay? That's what we're looking into."

Nanos also admitted that he and other authorities have intentionally kept many details from the public.
"There's so much that everybody wants to know, right? But I would be very neglectful and irresponsible as a police, law enforcement leader to share that with everybody," Nanos said. "We have information on this case that we think is going to hopefully lead us to solving this case, but it takes time."
When asked whether he would eventually solve the case, Nanos replied, "Absolutely."
