Law enforcement officials and the FBI have not commented on reports that a ransom note connected to the disappearance of Nancy Guthrie stated that she had died after being abducted.

Guthrie, the mother of Today host Savannah Guthrie, was reported missing from her home in the Catalina Foothills area of Tucson, Ariz., more than four months ago.

According to CNN and multiple other news outlets, law enforcement sources briefed on the investigation said a ransom note written in February claimed that Guthrie was dead. It said those who abducted her did not mean to kill her, but that she died shortly after going missing.

It followed a previous note demanding millions in bitcoin for her release, according to reports.

The existence of the ransom notes had previously been reported, but claims that Guthrie had died had not been publicized. CNN states that it had been aware of the contents of one of the notes and that Tucson TV station KOLD had received two notes. CNN reports that investigators believed the notes were from her kidnappers, and that both outlets had been asked by the family and law enforcement not to make the contents public.

In an Instagram video posted on Feb. 7, Savannah addressed Guthrie's apparent kidnappers, saying "we received your message and we understand," adding that they were prepared to pay for her return.

According to the Associated Press, the Pima County Sheriff's Department declined to comment on the note's contents. The FBI didn't respond to a request for comment.

Guthrie was last seen at about 9:45 p.m. on Jan. 31, when a family member dropped her off at her home after dinner. She was reported missing around noon the next day when she didn't show up at a friend's house to watch a church service online.

Police in charge of the investigation into Nancy's disappearance said the case remains active.

Authorities have not publicly identified a suspect or a motive in Nancy's apparent abduction. On Feb. 10, the FBI released footage of what it described as a masked, armed individual taken from her doorbell camera the morning she went missing.

The FBI is reportedly analyzing mixed DNA found at Nancy Guthrie's home, including a hair sample.

A combined reward of $1.2 million is being offered 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.

In the immediate aftermath of Nancy Guthrie's disappearance in February, Pima County Sheriff Chris Nanos said that while the 84-year-old mother of Today cohost Savannah Guthrie is "sharp as a tack," she has medical conditions that could become fatal without vital medications.

Former FBI special agent Harry Trombitas told Yahoo that, based on Nancy Guthrie's age, her physical condition at the time she was abducted and the amount of time that has passed, it “just makes me really skeptical that she's still alive.”

He added, “As an investigator, I wouldn't give up, and I know the family's not given up that she's still alive, and our goal as investigators is to bring her back fully alive, but if not, at least be able to bring her body back to her family so that they have closure.”

Since early May, the FBI has been analyzing mixed DNA from Nancy Guthrie's home, including a hair sample.

"I would think that they would have some results in the amount of time that's passed," former FBI Special Agent Harry Trombitas told Yahoo.

"I'm not surprised that they're not commenting on it," he said of the FBI. "As you develop suspects and maybe put them under surveillance … maybe you pick up a cigarette butt or a coffee cup that was discarded by a suspect. … You want to run that and have it compared to the DNA that was recovered, and see if there is a possibility that there's any connection in that.

"I know one thing we wouldn't want to do is come out with any bold statements, saying with 100% certainty that we know who this individual or individuals are, because we wouldn't want to cause them to react," Trombitas explained. "When we finally move in on them, we want them to be completely surprised that we were able to figure this out."

Former FBI Special Agent Harry Trombitas told Yahoo that it's a "little baffling" as to why reports of the contents of a second note from February, indicating that Nancy Guthrie had died, were being made to the public now.

"I know that in some of the cases that I've worked in my past, when the news is a little bit slow, and people start moving on to other things, and it's not a hot topic anymore, we might release a little tidbit of information just to generate a little public interest, like clearly what's happened here since the release of this information," Trombitas said.

"I think people once again are starting to focus on the Guthrie kidnapping case," he said. "All we need is that one tip to come from somebody that's in the know that could lead to the resolution of the case."

Following multiple reports that a second note sent by Nancy Guthrie's kidnappers to media outlets indicated that she had died, Today show cohost Savannah Guthrie issued another tearful plea for information about her mother's disappearance.

"I don't have any comment on this story, and I'm not involved in our coverage, but I can't pretend I'm not here," Guthrie said following an on-air report about the note.

"And so since I am, I want to just take the opportunity to ask people, to really, to beg people to come forward. Somebody knows something."

"This is a new story today that is on your radar," she continued. "But this is the life that my sister lives, that I live, that my brother lives, that our extended families live, that our children live, every day. And we are in agony. We cannot be at peace."

A note from Nancy Guthrie's purported kidnappers, sent days after she went missing, claimed she died shortly after being abducted, CNN and multiple news outlets have said.

Two notes were sent to media outlets in February in the wake of the 84-year-old's disappearance. The first note demanded a ransom of millions of dollars in bitcoin, while the second said Guthrie had died shortly after being taken, according to sources cited by CNN, CBS News and ABC News. The purported contents of the second note had not previously been made public.

The Pima County Sheriff's Department declined to comment on the new reports, but said the investigation "remains active and ongoing," according to the BBC. The department "continues to work closely with the FBI as investigators follow up on leads, review information, and pursue the facts surrounding this case," a spokesperson added.

Guthrie's daughter, Savannah, appeared to comment on the authenticity of the notes in March.

"There are a lot of different notes, I think, that came, and I think most of them — it's my understanding — are not real, and I didn't see them," she told NBC. "But I believe the two notes that we received, that we responded to, I tend to believe those are real."

CNN reported that investigators believed the notes were from her kidnapper.

Jessica Bobula, news director for the Tucson TV station KOLD, said on Monday that the station received several notes after Guthrie disappeared.

The FBI and the Guthrie family have not commented on the notes.

Savannah Guthrie called her husband Michael Feldman a "hero" in a Father's Day tribute posted to Instagram.

The Today show cohost shared an image of Feldman embracing their children Vale, 11, and Charley, 9, and added the caption: "Our hero. Happy father's day, @feldmike."

Guthrie married Feldman, a communications consultant and former White House staffer, in March 2014. The couple first met at Feldman's 40th birthday party in 2008 and began dating the following year.

Feldman shared his own tribute to Guthrie on Mother's Day in May, calling her "the strongest person I know."

Guthrie was previously married to journalist Mark Orchard between 2005 and 2009.

The Pima County Sheriff's Office issued a statement on Thursday saying it is aware of reports that were circulating online about an anonymous tip that was received by a search group in Mexico claiming Nancy Guthrie was buried in an unmarked grave near the Mexican border.

Ramona Guadalupe Ayala Ortiz, leader of the Nogales-based Buscando Corazones collective, told El Imparcial, a local news outlet, that the group searched the area but did not find the grave.

"We are aware of reports regarding an anonymous tip related to the Nancy Guthrie investigation that was provided to a group in Mexico. At this time, we have not been contacted by Mexican authorities," the sheriff's office said, adding: "This investigation remains active and ongoing, and we will continue to follow up on any credible information."

The Pima County Sheriff's Office announced late Thursday that officers arrested a man who was livestreaming in front of Nancy Guthrie's home.

Alexander Zabel Jr., who runs a YouTube true crime page called CriminalNetwork, was arrested around 5 p.m. local time after police had received several complaints from neighbors about his behavior.

"During the arrest process, a PCSD sergeant was knocked to the ground," the sheriff's office said. The confrontation was captured at the end of Zabel's livestream.

Zabel was taken into custody and booked into jail on charges of resisting arrest and public nuisance.

It was his second arrest in less than a week. On Monday, Zabel was arrested along with two other livestreamers amid a crackdown in Guthrie's Catalina Foothills neighborhood.

In that case, Zabel was facing two counts of "obstruction of a highway or public thoroughfare" and one count of public nuisance, according to KVOA-TV.

Savannah Guthrie was a guest cohost on the fourth hour of the Today show on Monday alongside her dear friend Jenna Bush Hager.

"It's hard when you're with your best friend to not be real," Guthrie told Hager. "You've asked me before if I'm ready. But I couldn't look at you, in this kind of setting, where we talk about life and not tell the truth about my life.

"I know maybe people wonder like, 'What's going on? How is she able to do that job? Is she not thinking about it? Did she forget?'" Guthrie continued. "No, never. Never."

Hager asked Guthrie whether coming back to the show brought her some hope or a spark.

"It is. It's a little respite," Guthrie said. "And you are my family. I don't think if I had any other kind of job I would've even tried to come back. I just felt like, what else should I do? And my mom would've said the same, like, 'Honey, just keep going, just keep going.' And so, I am."

Former FBI special agent Harry Trombitas told Yahoo that, based on his experience, there’s likely an FBI liaison communicating with the Guthrie family on any case updates.

“I'm sure that the FBI and other law enforcement agencies that are involved are giving the family more information than what the public is getting,” Trombitas said. “But I also think that the family is not getting everything just because we want to safeguard that information, and we don't want to have it compromised.”

Any publicly shared updates on the case from the Pima County Sheriff’s Department and the FBI have been sparse in recent weeks.

Former FBI special agent Harry Trombitas told Yahoo that while it can be frustrating that there haven’t been any updates on the investigation — certainly for the Guthrie family — the public should remain “patient” as “investigators are working day and night on this case.”

“There's been over 50,000 tips received, and I truly believe the names of the individuals involved are most likely in those tips,” Trombitas said. “It's just a matter of working through them. [Investigators] may already be on to somebody right now.”

Trombitas also noted that law enforcement can’t just go out and arrest someone. “You have to build a case and think about future prosecution,” he said, adding that things have to be done properly to make sure there are no mistakes.

Khloé Kardashian has described the disappearance of Nancy Guthrie as “heartbreaking,” four months after she went missing.

Speaking on her podcast Khloé in Wonder Land about the ongoing search for the 84-year-old, Kardashian said she did not understand why there is still no concrete evidence of her whereabouts.

“Nancy Guthrie. I mean, is that not heartbreaking?” she said on her podcast on Wednesday.

Kardashian was joined by Crime Junkie podcast host Ashley Flowers, who said she “could not believe” there was nothing to go on.

“I’m also very conspiratorial,” Flowers said, to which Kardashian replied: “Me too.”

“It’s so much,” Kardashian continued. “I can’t understand that in 2026 … that there’s not one piece of information. They’re not telling us.”

Pima County Sheriff Chris Nanos has said some information has been withheld from the public. “But it’s not done because we got a keep it secret,” he told KOLD. “It’s done because we got to protect our case.”

Flowers said that law enforcement withholding information is "so common," and that some missing-person cases may seem stagnant while detectives are working hard behind the scenes.

Pima County Sheriff Chris Nanos said the search for Nancy Guthrie remains active, as he issued an update on the case.

Speaking to local station KOLD in an interview published on Tuesday, Nanos said his department continued to work with the FBI and that he believed that an arrest would be made.

“We continue to work with our labs,” he said. “Whether it’s on the digital end or the biological end, DNA.

“It moves at a snail’s pace, I guess for some. But for my investigative team, and for me, we look at this as, no, this is doing exactly what we need it to do.”

“I believe, at some point in time, we will make an arrest on this case.”

Following criticism from FBI Director Kash Patel over local law enforcement’s handling of the case, Nanos added that FBI agents had been involved from “day one” and “continued to be involved.”

Savannah Guthrie announced on Monday that she will host a new primetime game show based on Wordle, the popular word game published by the New York Times, on NBC next year.

Guthrie made the announcement on the Today show with Jimmy Fallon, who is serving as the executive producer. The show will be filmed in Manchester, England, this summer, and is currently seeking contestants.

Production was delayed following Nancy Guthrie's disappearance. She thanked Fallon for waiting for her.

“When everything happened with me and my family, they just stopped everything and said, ‘We’ll wait for you,’” Guthrie said. “And Hollywood is like a really tough business, as you know, and I didn’t expect that. And I just want to say thank you. It means so much to me.”

In an interview with the Times, Savannah Guthrie said that she showed her mother the pilot in December.

She also acknowledged that hosting a game show with her mother still missing will be strange.

“Everything is strange right now,” Guthrie said. “It’s strange to get up and do the Today show every day, and it’s strange to say that I’m going to do a game show when your heart is broken.”

“Nothing about that has changed, and it’s not easy,” she added, “but I’m determined to put one foot in front of the other. And this is a joyous thing.”

It's now been 100 days since Nancy Guthrie was last seen.

A family member dropped her off at her home in the Catalina Foothills outside of Tucson, Ariz., after dinner around 9:45 p.m. on Jan. 31.

She was reported missing around noon the next day after she did not show up at a neighbor's house to watch an online church service.

Savannah Guthrie on Sunday paid tribute to her mother in a heartfelt Instagram post. Sharing a Reel compiled of home videos and family photographs, the “Today” show cohost marked the first Mother’s Day since the disappearance of her mom, Nancy Guthrie.

In the compilation, the missing 84-year-old is seen taking selfies with Savannah Guthrie and spending time with her grandchildren. A number of photos from Nancy Guthrie’s younger years are also included, and a video in which she’s seen saying “miss you.”

The caption reads: ”Mother, daughter, sister, Nonie – we miss you with every breath. We will never stop looking for you. We will never be at peace until we find you. We need help. Someone knows something that can make the difference.”

Mike Feldman, the longtime Democratic political consultant who has been married to Savannah Guthrie since 2014, posted a public Mother's Day tribute to his wife on Instagram on Sunday. The couple have two children, Vale and Charles.

"To the strongest person I know. Surrounding you with love on Mother's Day," Feldman wrote, accompanying the message with a heart, broken-heart and heart emoji.

Human remains discovered Thursday near Nancy Guthrie's Tucson home have been determined to be prehistoric and not connected to her disappearance, the Tucson Police Department said.

The remains were found by a true-crime livestreamer roughly seven miles from Guthrie's residence in the Catalina Foothills, near the intersection of River and Craycroft Roads, the Arizona Republic reported.

Todd Blanche, the acting attorney general, commented Wednesday on the FBI's involvement in the investigation into the disappearance of Nancy Guthrie.

On May 5, FBI Director Kash Patel criticized the Pima County Sheriff's Department's handling of the investigation, saying the FBI was initially "kept out" of the probe.

Speaking to NewsNation, Blanche said the agency is "ready, willing and able to help as much as we can" as the search for Guthrie continues.

He acknowledged reports of alleged "friction" between the FBI and Arizona law enforcement but said a "coordinated approach" was needed.

“I’ve seen those reports. We are here to help”, he said. “We don’t like interagency squabbles. Nobody likes that, that doesn’t help the investigation. But we are in a complete cooperative mode with the local law enforcement.”

The Pima County Sheriff's Department pushed back against Patel’s comments, saying in a statement: "The FBI was promptly notified by both our department and the Guthrie family. While the FBI Director was not on scene, coordination with the Bureau began without delay."

Kash Patel on Tuesday told Sean Hannity that the FBI was “kept out” of the investigation for four days.

“The first 48 hours of anyone’s disappearance is critical,” he said on the Hang Out With Sean Hannity podcast. “It’s a state and local law enforcement matter. What we, the FBI, do is say, ‘Hey, we're here to help. What do you need? What can we do?’ And for four days, we were kept out of the investigation.

“And when we were finally let in, Sean, look what we did.  We went in and got the Ring doorbell and we said, ‘Hey, is anyone talking to Google?’

“I called the leadership at Google and I said, ‘Look, we know that there was not a subscription service to capture all of the data that would’ve been captured had there been a subscription service. But can we go into the cache? Can we go into the data before it’s deleted and see what we can find?’”

Patel also said the FBI offered to send DNA evidence to the FBI Laboratory in Quantico, Va., for analysis. "We would have analyzed it within days and maybe gotten better information or more information. Our lab's just better than any other private lab out there, and we didn't get a chance to do that. So I understand everybody's frustrations on that."

In a statement, the Pima County Sheriff's Department pushed back at Patel’s comments, saying Sheriff Chris Nanos provided “immediate local leadership and oversight.”

"A member of the FBI Task Force was also notified and present at that scene working alongside our personnel," the statement said.

"The FBI was promptly notified by both our department and the Guthrie family. While the FBI Director was not on scene, coordination with the Bureau began without delay."

The statement added that decisions regarding evidence processing were made “based on operational needs.”
