More than seven months after Nancy Guthrie disappeared from her Tucson, Arizona, home, an anonymous tip prompted a volunteer group in Mexico to launch its own search for the missing 84-year-old woman.

The new lead emerged in May, when Buscando Corazones Nogales, a volunteer organization based in Nogales, Sonora, received a phone call from an unidentified person claiming to know where Guthrie was buried. According to reports cited by PEOPLE and local Mexican media, the caller said her remains could be found in the Mariposa area, near Nogales and close to the U.S.-Mexico border.

The information was serious enough for members of the volunteer group to organize searches in the area. Ramona Guadalupe Ayala Ortiz, who leads the organization, said the anonymous caller directed them toward an area where Guthrie was allegedly buried in a shallow, unmarked grave. Volunteers subsequently searched several locations, hoping to find evidence that could either confirm or rule out the information.

The searches, however, did not produce evidence confirming the tip. Local reporting indicated that neither volunteers nor authorities found remains or other material that established Nancy Guthrie had been taken to Mexico. The anonymous information therefore remains an unverified lead rather than a confirmed breakthrough in the investigation.

Guthrie was last seen at her Tucson home on January 31, 2026, and was reported missing the following day. Investigators have treated the disappearance as a suspected abduction rather than a voluntary departure. Evidence recovered from her home, including biological material, has remained part of the investigation, while surveillance footage showed activity involving a masked individual around the time she disappeared.

The case has attracted international attention largely because Guthrie is the mother of Savannah Guthrie, the NBC Today co-anchor. Savannah and her family have repeatedly appealed to the public for information that could help investigators determine what happened to Nancy and locate her.

Over the months since the disappearance, investigators have received a number of tips and purported claims about Guthrie’s whereabouts. Some have led authorities or independent groups to examine specific locations, while others have failed to produce useful evidence. Authorities have also warned the public about scams and false information circulating online around the case.

The Mexico search illustrates the difficulty investigators face in separating potentially meaningful information from unverified claims. An anonymous tip can point investigators toward a location, but without physical evidence, corroborating witnesses or other independently verified information, it cannot establish what happened to Guthrie.

The search near Nogales also occurred against the backdrop of an investigation that has already involved extensive efforts in and around Tucson. Authorities have conducted searches, reviewed surveillance footage and examined forensic evidence while continuing to ask the public to come forward with information.

As of September 2026, Nancy Guthrie has still not been located, and no suspect has been publicly identified or arrested in connection with her disappearance. Recent public attention has continued to focus on the case, including renewed appeals from Savannah Guthrie for anyone with information to contact investigators.

The anonymous Mexico tip has therefore added another unanswered lead to an already complicated investigation. For now, there is no verified evidence showing that Nancy Guthrie was buried near Nogales, and the circumstances surrounding her disappearance remain under investigation.

For her family, the uncertainty continues. Seven months after Nancy disappeared, they are still seeking reliable information that could finally establish what happened to her and bring her home.
