The Pima County Sheriff’s Department is investigating a damaged utility box around the corner from Nancy Guthrie’s home as the desperate search for Today cohost Savannah Guthrie’s mother continues in its second month.

Investigators believe it could be connected to a reported internet outage that occurred around the time she disappeared in the early morning hours of Feb. 1, which disrupted nearby home surveillance cameras.

Savannah Guthrie reunited with her coworkers at the Today studio in New York City last Thursday. She thanked her colleagues for their support, shared hugs with her coanchors and expressed her interest in returning to the show when the time was right.

“I think her coming here, just being able to be with us and for us to be able to hug her, I think it’s a step,” Today host Sheinelle Jones told the audience. “I don’t know what’s ahead of us, but all I know is it is a step.”

Though there have been no significant breakthroughs in the search for Nancy Guthrie in recent weeks, Pima County Sheriff Chris Nanos told Today last Tuesday that he believes investigators are “definitely closer” to solving the case. “We’ve got a lot of intel, a lot of leads, but now it’s time to just go to work,” he said.

The family of Nancy Guthrie, 84, is offering $1 million for information leading to her “recovery.”

Anyone with information is encouraged to call the Pima County Sheriff’s Department tip line at 520-351-4900 or the FBI tip line at 1-800-CALL-FBI.

The Pima County Sheriff’s Department confirmed to NBC that it is investigating a damaged utility box located around the corner from Nancy Guthrie’s house. It could be connected to an internet outage reported around the time she disappeared in the early morning hours on Feb. 1, potentially disrupting the availability of video evidence from nearby home surveillance cameras.

Federal investigators are examining whether internet service disruptions in Nancy Guthrie’s Tucson, Ariz., neighborhood the night she vanished could be tied to the abduction.

Guthrie’s neighbors told NewsNation their home security camera footage from that night is missing or marked “not available,” and authorities have reportedly asked residents about unusual connectivity problems around Feb. 1.

Savannah Guthrie met with her colleagues in New York City on Thursday morning for a tearful reunion as the search for her mother continues into its second month. Photos from the studio show Guthrie wiping away tears, hugging her coworkers and receiving a kiss on the cheek from her Today cohost Hoda Kotb.

Guthrie hasn’t appeared on the show since Jan. 30, two days before her mother, Nancy Guthrie, was reported missing.

After the visit, host Jenna Bush Hager told the Today audience that Guthrie said she planned to return to the show but doesn’t have a timeline for when that might happen.

“She said that she has the intention to return to the show. Even though it feels like the hardest thing to do, it’s also her home and where she feels so loved,” Bush Hager said. “I don’t know when she is actually returning to the show, but she was here and that felt so good to get to hug her.”

DNA analysis of genetic material pulled from a pair of black gloves found two miles from Nancy Guthrie’s home led back to a local restaurant worker who is not connected to the case, the Pima County Sheriff’s Department said on Wednesday.

In mid-February, the sheriff’s department said that DNA from the gloves did not match any entries in the FBI’s national genetic database.

The department told local media that it found a total of 16 pairs of gloves in the area around Guthrie’s house, most of which were later traced back to members of search teams.

Pima County Sheriff Chris Nanos believes that investigators are “definitely closer” to identifying a suspect or suspects in the case of Nancy Guthrie’s disappearance, he told NBC in an interview that aired on the Today show on Tuesday.

Nanos said that a dedicated team from his department’s homicide unit is working with the FBI and investigating the case under the presumption that Nancy Guthrie is still alive. He said they’re continuing to pursue thousands of leads.

“I think the investigators are definitely closer,” Nanos said.

During the interview, Nanos was asked about a neighbor’s doorbell camera video, obtained by Fox News Digital. The video shows a car speeding past the neighbor’s house, about 2.5 miles away from Nancy Guthrie’s home, at 2:36 a.m. on Feb. 1, just hours before she was reported missing.

“Look, what I would tell you is this: We’re aware of it, and we’re looking into it, just like any other piece of evidence,” the sheriff said, adding that authorities have not been able to identify the car yet.

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

When asked about the mixed DNA found at Nancy Guthrie’s home, Nanos suggested that it might be a mixture of DNA from several people. Experts say it can be difficult to extract the DNA profile from one person in these mixtures.

On Feb. 13, Luke Daley was detained for several hours by Pima County sheriff’s deputies and was questioned by the FBI in connection with Nancy Guthrie’s disappearance. For the first time since being detained and cleared, Daley is speaking out in an interview with Briana Whitney, a true crime correspondent for Arizona’s Family, saying he had nothing to do with Nancy Guthrie’s disappearance.

“It’s not me,” Daley said, referring to the masked person in the FBI-released doorbell camera video. “I don’t see the resemblance of it looking like me.”

He said he doesn’t know who is involved in Guthrie’s disappearance, and if he did, he would “happily” tell the authorities.

Daley said that on the night he was detained, he was driving home in his Range Rover when two sheriff’s cars pulled him over and told him to get out of the vehicle, before cuffing him and detaining him for about four to five hours. When he asked what he was being detained for, they didn’t tell him.

Daley said he just learned that Nancy Guthrie lived nearby and has never met her. He said he knew who she was only because his mom was following the case. Authorities towed his Range Rover for a search, which he ultimately got back. They also took his cellphone for a search, which he still hasn’t gotten back. In the meantime, a SWAT raid was being conducted at his home.

“The worst part was my mom not being there,” Daley said, adding that she has health issues. “I’m thinking the worst.” Without a cellphone, he couldn’t get in touch with her but discovered the next day that she had gone to a neighbor’s house.

Daley has called the ordeal a “nightmare” and feels like he can’t go out in public. He said he just wants Nancy Guthrie to return home safely and for his name to be cleared.

Savannah Guthrie visited a memorial outside of her mother’s home in Tucson, Ariz., on Monday, marking one month since Nancy Guthrie disappeared. Savannah was joined by her sister Annie and her brother-in-law, Tommaso Cioni. The three were seen hugging one another as they added flowers to a growing tribute near Nancy Guthrie’s mailbox.

It’s been nearly a month since Nancy Guthrie was reported missing from her home near Tucson, Ariz. Police believe that Guthrie, the 84-year-old mother of Today show cohost Savannah Guthrie, was abducted.

The Pima County Sheriff’s Department has announced that it is refocusing its resources to detectives specifically assigned to the Nancy Guthrie case.

“This remains an active investigation and will continue until Nancy Guthrie is located or all leads have been exhausted,” the sheriff’s department said in a case update on Friday, adding that “resource allocation may fluctuate” in the search for Guthrie, who was reported missing on Feb. 1.

Police confirmed reports that investigators “actively reviewing surveillance video of vehicles traveling in the Catalina Foothills area,” including footage of a vehicle taken from a Ring camera about 2.5 miles away from Guthrie’s home.

The sheriff’s department said it has “asked homeowners in the surrounding community to submit any relevant footage and encourage anyone who has not yet done so” through a dedicated link on its website.

Days after announcing her family's $1 million reward for information leading to their mother's "recovery," Savannah Guthrie shared a video on Instagram Friday of a Today show report about how to submit an anonymous tip to the FBI.

"Please — be the one that brings her home," Guthrie wrote in a caption. "Tips can be anonymous, reward can be paid in cash, as explained here."

Despite receiving tens of thousands of tips, law enforcement officials have expressed concern that there may be people reluctant to contact the FBI out of fear their identity will be compromised in such a high-profile case.

Savannah Guthrie has been absent from the Today show since her mother was reported missing on Feb. 1. The grueling weeks-long search for Nancy Guthrie has led to speculation that Savannah may not return to NBC’s long-running morning show.

Citing two unnamed network sources, CNN reported on Thursday that Guthrie “intends to return to work” at the Today show “at some point.”

When that will happen remains unclear. Hoda Kotb, who departed the Today show early last year, has been filling in as cohost in Guthrie’s absence.

As the search for Nancy Guthrie nears the one-month mark, the FBI continues to analyze thousands of hours of video footage it has amassed since the investigation into her disappearance began.

NBC News reports that among the estimated 10,000 hours of video is Ring camera footage — obtained by Fox News Digital — of a car driving about 2.5 miles from Guthrie’s home, possibly en route from the crime scene, around 2:30 a.m. on the morning she was reported missing.

Investigators are also continuing to evaluate tips. After Savannah Guthrie posted a new video to Instagram earlier this week announcing the family’s $1 million reward for information leading to Nancy Guthrie’s “recovery,” an official told ABC News that the bureau received roughly 1,500 tips. According to CNN, more than 750 of those tips were deemed “credible.”

Elizabeth Smart, a kidnapping survivor turned activist and subject of a recent Netflix documentary, was asked in a podcast interview whether she is "triggered" by the Nancy Guthrie case.

"I'm not triggered by it," Smart said on the "Ladygang" podcast Wednesday. "But I know like what law enforcement will tell you: If a person disappears and they're not found within the first 24 to 48 hours, the chances of their survival drop down to almost 0%. I mean, it's, it's almost like they're dead. But I just always feel like we, we can't give up, because if that was the mentality around my case, then I wouldn't be here today."

Smart was abducted from her home in 2002 at age 14 and rescued nine months later, after people recognized her captors, Brian David Mitchell and Wanda Ileen Barzee, from an America's Most Wanted episode about her disappearance.

"I mean, I did come back, and there are other victims who do come back," Smart said. "And so even though every passing day feels like we're losing more and more hope or seems like it's less likely that she'll be found. I think we just have to remind ourselves that we can never give up. We need everybody's help. We need everyone to keep their eyes open and that someone will see something. Someone does know something. And if we stay alert and we stay aware and we don't just think, 'Oh, well that seemed kind of strange. But if that really is strange, someone else knows more than me.' Don't hesitate. Don't think that. Just pick up the phone, call law enforcement, tell them what you know, tell them what you see. And because you never know — what is the worst thing that can happen? The worst thing that can happen is that you're wrong.

She added: "That's not a big deal. I'd rather be wrong than keep my eyes closed to a crime happening."

ABC News reports that the FBI is reducing the number of personnel investigating Nancy Guthrie’s disappearance in Tucson, Ariz., and "relocating its command post" to Phoenix.

"The FBI will keep agents in Tucson and continue to partner with the Pima County Sheriff's Department," the report said, "but many agents are returning to Phoenix to work the case from there."

It added that the move should not be seen as an indication that investigators are giving up in the search for the 84-year-old, who was reported missing on Feb. 1.

NBC News reported that it was “related to efforts to turn the home back over to the Guthrie family."

Authorities are reportedly preparing to return Nancy Guthrie's home to her family as the search for the 84-year-old Guthrie nears the end of its fourth week.

Guthrie's home in the Catalina Foothills north of Tucson, Ariz., where she was last seen, has been at the center of the investigation since she was reported missing on Feb. 1.

There was law enforcement activity at the home on Wednesday, with several investigators seen standing near the front door, where Guthrie's doorbell camera captured images of a suspect. Other investigators were seen taking photos of a door at the back of her house.

According to NBC News, the "activity seen Wednesday is related to efforts to turn the home back over to the Guthrie family."

The Pima County Department of Transportation also announced plans to restrict parking on Guthrie's street beginning on Feb. 26.

The restrictions are being enacted to "relieve area residents from chaotic conditions caused by a large media and social media streamer presence," the department said.

Dominic Evans, an elementary schoolteacher who plays drums in a band with Nancy Guthrie’s son-in-law Tommaso Cioni, told the New York Times that his family has been targeted by internet sleuths who believe he is the suspect seen in the doorbell camera footage.

“I feel like someone’s taken my name,” Evans said.

Asked for what reason, he replied: “I don’t know — monetary, clickbait, to be relevant, entertainment — but there are innocent people that get hurt.”

Evans, who lives with his wife and their three sons in Tucson, Ariz., said he spoke with investigators from the FBI and the Pima County Sheriff’s Department two weeks ago for roughly 40 minutes and hasn't heard from them since. He said he was at home with his family the night Nancy Guthrie went missing.

After the FBI released the footage of what it described as "an armed individual" in a ski mask on Guthrie's doorstep, people began to speculate online whether it was Evans. The same day, people descended on his house, forcing Evans and his wife to stay inside and tell their oldest son, a teenager, not to come home.

“It was all night looking through the window, trying to not let any light out,” Andrea Evans, a principal in a neighboring school district, told the paper, describing being “scared numb” by the ordeal.

The Pima County Sheriff's Department issued a brief update to the media overnight, saying that police and the FBI "continue to work around the clock on this investigation and are actively pursuing all viable leads."

It said that "all evidence collected from the crime scene and related search locations" has been submitted for forensic analysis and is being processed.

The sheriff's department said the $1 million reward offer for information leading to Nancy Guthrie's recovery was "determined by the Guthrie family."

Police also said that the Guthrie family requested “No Trespassing” signs be placed around Nancy’s residence. "Members of the media are expected to observe these postings and comply with the law," the sheriff's department said.

The sheriff's department added that while it has been distributing updates to the media "on an almost daily basis," it will now "limit further updates to instances when new information warrants release."

While announcing a $1 million reward on behalf of her family on Tuesday for the “recovery” of Nancy Guthrie, Savannah Guthrie also announced a $500,000 donation to the National Center for Missing and Exploited Children.

The nonprofit was founded by John and Revé Walsh in 1984 with a mission to “help find missing children, reduce child sexual exploitation and prevent child victimization.”

Savannah Guthrie said her family understands “that we are not alone in our loss.”

“We know there are millions of families that have suffered with this kind of uncertainty,” she said. “We are hoping that the attention that has been given to our mom and our family will extend to all families like ours.”

In a statement posted to Facebook, the organization said that it was “incredibly grateful to the Guthrie family for turning their personal heartbreak into a commitment to helping others.”

The FBI's Phoenix field office posted a message on social media on Tuesday announcing the private $1 million reward from Nancy Guthrie's family and urging people with “well-wishes or case theories” to stop calling its tip line.

"If you have firsthand knowledge of Nancy’s whereabouts or any information about where she may be located, please contact the FBI tip line at 1-800-CALL-FBI (1-800-225-5324)," the message read.

"To help keep the tip line available for actionable investigative law enforcement leads, please submit only serious and detailed fact-based information — no well-wishes or case theories," the FBI said, adding: "The tip line is not for personal messages to the Guthrie family."

The Pima County Sheriff's Department had issued similar pleas asking people not to call 911 with their opinions on the case.

With the search for Nancy Guthrie now in its fourth week, Savannah Guthrie posted a new video to Instagram offering $1 million for information leading to the “recovery” of her mom.

"It is day 24 since our mom was taken in the dark of night from her bed," the Today show cohost said through tears. "And every hour and minute and second and every long night has been agony since then, of worrying for her, fearing for her, aching for her and most of all just missing her, just missing her."

Savannah Guthrie thanked people for keeping the family in their prayers.

"Please keep praying without ceasing. We still believe in a miracle. We still believe that she can come home," she said. "Hope against hope. As my sister says, we are blowing on the embers of hope.”

“We also know that she may be lost. She may already be gone,” Savannah Guthrie continued. “If this is what is to be, then we will all accept it. But we need to know where she is. For that reason, we are offering a familial reward of up to $1 million for any information that leads us to her recovery.”

She added: "Someone out there knows something and can bring her home. Somebody knows. And we are begging you, please come forward now."
