The last time anyone saw Nancy Guthrie, she was walking into the garage of her Tucson, Arizona home at 9:50 p.m. on a Saturday night. She was 84 years old, living alone in the Catalina Foothills neighborhood she called home. By the next morning, February 1, 2026, she had vanished entirely. More than four months later, the search for her has crossed an international border, and the latest development is stranger and more unsettling than almost anything that came before it.
A volunteer nonprofit organization called Buscando Corazones de Nogales Sonora received a call on Mother’s Day, pointing volunteers to an unmarked grave near the Mexican border town of Nogales. The caller, a man, told the group to “go look in that area” and said “that’s where the missing woman from Tucson was.” The tip arrived with no name attached, no verifiable details, and no way to assess its credibility. And yet it sent volunteers into the desert on both sides of the border, digging through terrain where, it turns out, hidden graves are not exactly rare.
The search produced nothing. No remains, no clothing, no evidence of any kind. But the volunteers aren’t done. And in a case where the official investigation has gone months without a single public breakthrough, even an unverified anonymous tip in a foreign country carries a weight it wouldn’t otherwise have.
A Disappearance Treated as Abduction From the Start
The FBI, working alongside the Pima County Sheriff’s Department, investigated Nancy Guthrie’s disappearance from the outset as a kidnapping. She was considered a vulnerable adult who had difficulty walking, relied on a pacemaker, and needed daily medication for a heart condition – all factors that made her survival without assistance deeply precarious. Authorities were unambiguous from the start: she did not leave voluntarily.
The FBI released surveillance footage and images showing a masked, armed person approaching Guthrie’s home and deliberately covering her doorbell camera, the first substantial piece of public evidence in the search for the missing mother of “Today” show host Savannah Guthrie. The footage, when it came, was chilling not just for what it showed, but for the level of preparation it implied. Investigators concluded the masked suspect scouted the home in advance. The FBI described the person as the “suspect in the kidnapping of Nancy Guthrie,” saying the man is approximately 5-foot-9 to 5-foot-10 with an average build.
Drops of her blood were found on the front porch, and the FBI moved to analyze mixed DNA recovered at the scene. The agency said it was taking seriously at least one ransom demand from people claiming to have abducted her, though it has not confirmed the note’s authenticity. The ransom note included two deadlines – one that passed in the week after her disappearance and another that expired the following Monday. Neither produced any resolution.
FBI Director Kash Patel said publicly that the bureau was kept out of the case for the first four days, calling the early hours of a missing person investigation especially critical. That revelation added a layer of frustration to an already fraught situation. Once fully involved, the operation expanded quickly, with approximately 150 agents assigned to the investigation.
A Search Warrant, a Traffic Stop, and No Charges
The most dramatic early development came in February, when authorities detained a person of interest in a traffic stop south of Tucson. The subject was stopped and detained near the border in Rio Rico, a town around 60 miles south of Tucson. The Pima County Sheriff’s Department and the FBI conducted a court-authorized search of a home in the desert community where an individual named Carlos Palazuelos was staying.
Palazuelos spoke to media in Spanish outside his house in Rio Rico. He confirmed his home was searched per a warrant. He said that agents told him he looked like the person in security camera footage released by the FBI, and that while he worked as a delivery driver, he didn’t remember if he had delivered anything to Guthrie’s address. He was released hours after being brought in, and no arrest has followed.
The case continued generating leads without resolution. An FBI official said the agency amassed as many as 10,000 hours of video in the investigation. Former FBI special agent Harry Trombitas stated that while it can be frustrating that there haven’t been any public updates, investigators are working day and night, and more than 50,000 tips have been received – and that the names of those involved are most likely somewhere in that pile.
The Reward That Changed the Volume of Tips
Savannah Guthrie announced the family reward in an emotional plea on social media. “It is Day 24 since our mom was taken in the dark of night from her bed. And every hour and minute, second, and every long night, has been agony since then,” she said.
NBC News reported that the family was offering up to $1 million for any information leading to her recovery, a figure that combined with the FBI’s standing reward to bring the total to $1.2 million. Pima County Sheriff Chris Nanos had reportedly pushed back on the idea of a large reward, concerned it would flood the tip line with bogus leads and muddy the investigation. The concern was reasonable: when significant money is attached to a high-profile case, not every tip that comes in reflects genuine information. But with weeks passing and no arrests, the family moved forward anyway.
The volume of tips that followed was immediate. Within 48 hours of the announcement, the number had surpassed 1,500 tips, marking one of the most significant developments in a case that had stretched into its 26th day without a suspect.
The Volunteer Search and the Nancy Guthrie Buried Mexico Tip
Six weeks after Nancy Guthrie disappeared, a separate thread in the investigation had been developing south of the border. According to a Yahoo News report, the Buscando Corazones Nogales collective – a group that works to find missing people in Mexico – received an anonymous tip about her possible whereabouts in the Mariposa area near Nogales, Sonora. The group’s leader, Ramona Guadalupe Ayala Ortiz, confirmed that the organization was told Nancy was buried near one of the streams in that area.
In a message to PEOPLE magazine, the organization wrote, “In May, the tip was received. The anonymous source said she is here. Yes, we will continue searching.”
Up to 15 volunteers searched the area on May 16 but found nothing. After receiving additional information through a second anonymous call, searchers returned to the site on June 10 and again came up empty-handed. They believe they were close and plan to search again, roughly four miles south of the Arizona border.
The location carries added weight because of what Buscando Corazones has already found there. In previous searches, the group discovered more than 25 clandestine graves in the same region and recovered the remains of at least 32 people. That history is part of why the tip was taken seriously despite having no verifiable source. FBI agents were not dispatched because they have no jurisdiction in Mexico.
What Official Authorities Have Said
The Pima County Sheriff’s Department issued a measured response to the Mexico developments. In a statement, the department said it was “aware of reports regarding an anonymous tip related to the Nancy Guthrie investigation that was provided to a group in Mexico,” but added, “At this time, we have not been contacted by Mexican authorities.” The department confirmed that “the investigation remains active and ongoing” and that it will “continue to follow up on any credible information.”
Mexican authorities struck an even more cautious tone. Officials stated there was no evidence, information, or objective elements suggesting that Nancy Guthrie entered, remained in, or traveled through the state of Sonora. That doesn’t rule out the anonymous tip as a possible lead, but it reflects the absence of any official cross-border coordination in this specific search.
The possibility of Guthrie’s kidnapping being cartel-related wasn’t a new theory – it was among those floated when she first went missing. Authorities have not confirmed any cartel involvement, and even if she is found in Mexico, that alone would not establish who was responsible.
The Groups Who Won’t Stop Looking
The search in Mariposa is being led by the Buscando Corazones collective, but they’re not the only volunteer group that tried to help. CNN reported that Madres Buscadoras de Sonora (Searching Mothers of Sonora) traveled to Arizona to join the search, though the Pima County Sheriff’s Department denied their application for a field search permit on the grounds it could disturb the official investigation. The group’s founder, Ceci Flores Armenta, started the organization in 2019 after her sons disappeared. Since its founding, it has grown into a national network that has helped locate more than 5,000 people across the country, alive and dead.
Their methods are highly specific. Volunteers probe soil with metal rods to detect disturbances or decomposition smells, target disturbed earth, and conduct “life searches” by approaching unhoused individuals with flyers, food, and conversation. Denied access to the main search sites, some members distributed flyers bearing Guthrie’s image around Tucson while others remained in Mexico to continue searching near Nogales.
Lupita Tello, who joined the group after her son disappeared in Mexico in 2020, said she and two other volunteers continued to post flyers on bus stops and utility poles near Nancy Guthrie’s home, with plans to do the same in Nogales, Mexico. “We know the soil. We know when someone has dug deep or when there is a shallow grave,” Tello said. “We hope we can help because we understand the pain of having a missing relative.”

Where the Case Stands Now
More than four months after Nancy Guthrie was taken from her home, as of June 12, 2026, she has not been located. No arrests have been made, and no suspects have been publicly identified. Pima County Sheriff Chris Nanos has stated that he is committed to the case and believes an arrest will eventually be made.
The anonymous tip that sent volunteers into the desert near Nogales may amount to nothing. It may be a hoax, a mistaken lead, or the work of someone trying to derail the investigation. Separately, an unnamed individual contacted multiple media outlets claiming they had spotted Nancy south of the Mexican border and demanding Bitcoin in exchange for information – the kind of exploitation that emerges around high-profile cases and that investigators have to filter out alongside genuine leads.
What doesn’t go away is the image of a group of volunteers, many of them mothers who know exactly what this kind of loss feels like, pressing metal rods into desert soil south of a border, following a lead that official agencies can’t touch. They’ve found thousands of people over the years in circumstances no one wanted to believe were possible. They’re still looking. “Mother, daughter, sister, Nonie – we miss you with every breath. We will never stop looking for you,” Savannah Guthrie wrote in a public post.
The case has 50,000 tips in its pile, 150 FBI agents assigned to it, 10,000 hours of video under review, and a $1.2 million reward attached to any information that could bring it to a resolution. Someone, somewhere, knows something that changes the picture. The question no one has been able to answer yet is whether that person will come forward.
