One of Nancy Guthrie's neighbors said that their camera closest to the missing 84-year-old's home was missing video from the overnight hours of Feb. 1, when she disappeared.
According to NBC News, a couple that lives adjacent to Guthrie's home said they have four cameras on their property, noting the one closest to the missing 84-year-old's home was "not available" during that specific timeframe.
The neighbor said it seemed "uncanny" that the security video wasn't available during that timeframe.
“That’s really weird, isn’t it?” they said.
A neighbor’s report that a security camera closest to Nancy Guthrie’s home was “not available” during the overnight hours of Feb. 1 has sparked speculation about whether a Wi-Fi jammer could have been used in the 84-year-old’s disappearance.
But experts say the publicly available evidence does not strongly support that theory.
The neighbor told NBC News that while they have four cameras on their property, only the one nearest Guthrie’s home was missing footage during the critical timeframe. The timing was described as “uncanny.”
Morgan Wright, CEO and founder of the National Center for Open and Unsolved Cases, said true Wi-Fi jamming typically disrupts all devices within range.
"If they were using Wi-Fi jammers, then I would expect that we would not be able to see any video from the front door cameras," Wright told Fox News Digital.
He said that when jammers are active and persistent, footage often degrades or cuts out entirely.
"As you get closer with the jammer, the signal starts getting interfered with," he said. "The closer you get to the source of the signal emination, which is the router with the Wi-Fi access point, then you might get a total blackout."
However, video released publicly in the case does not appear glitchy or distorted, he noted.
Lisa Miller, a retired detective and former law enforcement executive with the Colorado Attorney General’s Office, said while Wi-Fi jammers have been used by organized burglary groups, she considers it less likely in this case.
"The video of the porch monster released by the FBI, didn’t appear glitchy. At all," Miller told Fox News Digital.
Miller said if a device were involved, it could just as easily have been a handheld radio rather than a more sophisticated tool.
"Even police car laptops have glitched during traffic stops of someone with a jammer. I think it more likely, if that spot people think is an antenna in his pocket…or if he had any device, it would be a small handheld radio. I think it’s smarter to use that than a burner phone. The criminals know what the FBI CAST team can do."
When asked about reports of a potential internet outage in Guthrie's neighborhood at the time of her disappearance, a Pima County Sheriff's Department spokesperson told Fox News Digital that they cannot comment.

TUCSON, Ariz. — As a growing memorial outside Nancy Guthrie's Tucson-area home continues to draw visitors, new questions are emerging about whether investigators are monitoring the site.
Guthrie, the 84-year-old mother of "Today" co-host Savannah Guthrie, is believed to have been abducted from her home in the early hours of Feb. 1.
"They could [have eyes on the memorial], we're just not seeing it," Betsy Brantner Smith, spokesperson for the National Police Association and a retired police sergeant, tells Fox News Digital. "They could be keeping track of it, but we're not seeing the cameras."
Yellow flowers, handwritten notes, artwork and even an open letter addressed to the "kidnapper" have been left at the makeshift tribute in front of her home.

{{#rendered}}Pima County Sheriff Chris Nanos says his agency has "moved on" from two men, Luke Daley and Carlos Palazuelos, who were once detained in relation to the Nancy Guthrie investigation.
"And what I will say is, we had what we believed to be probable cause to take action against both those individuals and the residence they occupied. That probable cause that we felt was strong was given to the U.S. Attorney, the county attorney and a magistrate, a judge, and they agreed that, 'yes, here's a warrant, go perform your duties.' That court order, that warrant in both cases was served, and we got what we got from it, and we're moving on," Nanos said.
Savannah Guthrie shared a message with 'Today' show staff on Thursday morning during a visit with colleagues.
According to NBC, Savannah Guthrie told colleagues that she still has hope as her 84-year-old mother remains missing.
“I wanted you to know that I’m still standing, and I still have hope, and I’m still me,” she said. “And I don’t know what version of me that will be, but it will be.”
“I’m holding onto my faith,” she added. “I still believe. And as my mom would say, ‘Where else would I go?"
During her visit with 'Today' Show staff, Savannah Guthrie also said she would be returning to work at some point.
“I have every intention of coming back,” she said. “I don’t know how to come back, but I don’t know how not to. You’re my family. And I would like to try.”
Investigators continue to search for Nancy Guthrie, who is believed to have been taken from her home in the early hours of Feb. 1.
FBI investigators went back to Nancy Guthrie’s neighborhood on Thursday and asked homeowners if they had any issues with their internet on the night the 84-year-old went missing on Feb. 1, according to NBC News.
Several neighbors told investigators that they had glitches with their internet connection on the night of Feb. 1.
Pima County Sheriff Chris Nanos earlier declined to say specifically if he believed the suspect may have had a Wi-Fi jammer, stating that investigators are looking at every angle of the surveillance video.
