The sheriff for Pima County, Arizona says investigators are “definitely closer” to an arrest in the Nancy Guthrie missing person case.

In an interview with NBC News, Pima County Sheriff Chris Nanos said police are investigating a car that passed by Nancy Guthrie’s Tucson area home the night she went missing.

Nanos said that a Ring camera video obtained by Fox News Digital shows a car driving past a home in Guthrie’s neighborhood about 2.5 miles away from her house at 2:36 a.m. on Feb. 1.

Guthrie was reported missing by her family hours later that day.

“I think the investigators are definitely closer,” he told NBC News.

Nanos said the sheriff’s department’s homicide unit is working closely with the FBI on the case. The homicide unit’s involvement implies that the 84-year-old mother of “Today” show host Savannah Guthrie is deceased.

But Nanos added that he believes Nancy Guthrie is still alive after 32 days.

Evidence shows she may have been taken from her bed between 2 a.m. and 2:30 a.m. on February 1. She was last seen by her family on January 31.

“Look, what I would tell you is this: We’re aware of [the car], and we’re looking into it, just like any other piece of evidence,” Nanos said.

He said authorities have not been able to identify the car in the footage.

“We’re looking at that vehicle as well as hundreds of thousands of other vehicles that were out driving that time of day,” Nanos said.

Investigators are also looking into who purchased a backpack similar to the one worn by the suspect in Nancy’s Nest video footage.

The $10 backpack is exclusively sold by Walmart, but Sheriff Nanos says it may not have been bought at a Walmart.

“We’ve now learned that maybe it wasn’t purchased out of Walmart,” he told NBC News. “That backpack is new, is exclusive to Walmart, but who’s to say I didn’t buy it and put it on eBay? … That’s what we’re looking at.”
