A volunteer organization dedicated to locating missing persons in Mexico recently mobilized near the U.S.-Mexico border following an anonymous tip suggesting the elderly mother of a prominent television personality had been buried in an unmarked grave in the region. The tip, received on Wednesday by Buscando Corazones Nogales, a Nogales-based collective, directed searchers to an area known as Mariposa, located more than 70 miles south of where 84-year-old Nancy Guthrie was last seen alive.

Nancy Guthrie, the mother of NBC "Today" show anchor Savannah Guthrie, was reportedly taken from her Catalina Foothills home in Tucson, Arizona, during the early morning hours of February 1. Her disappearance initiated an extensive investigation that has continued for months without producing any arrests or confirmed leads in Arizona. The anonymous caller provided specific coordinates for a grave near a stream within the Mariposa zone, an area northwest of the border city of Nogales, which is well south of Guthrie's Arizona residence.
Ramona Guadalupe Ayala Ortiz, leader of Buscando Corazones Nogales, confirmed the details of the tip. "We received an anonymous call telling us that the woman’s [Guthrie’s] remains were in the Mariposa area — in a grave over a stream," Ayala Ortiz told the publication El Imparcial. Acting on this detailed information, search teams were deployed into the field almost immediately, pushing deeper into the Mariposa terrain than in any previous mission. This operation involved penetrating sections of land that had not been previously examined by the collective.
The Mariposa area is unfortunately no stranger to grim discoveries. Buscando Corazones Nogales has previously recovered 25 unmarked graves from within that same stretch of ground during earlier operations this year, highlighting the region's challenges related to missing persons and unidentified remains. Despite the extensive nature of Wednesday's search and the specific details provided by the anonymous source, the team concluded their operation without locating any evidence connected to Nancy Guthrie.
However, this setback has not diminished the group's resolve. Ayala Ortiz confirmed the collective's intention to mount additional search operations across the Mariposa zone. These future efforts will continue to pursue leads regarding Guthrie's whereabouts while also searching for any other unidentified individuals who may be buried in the area. The Sonora State Commission for the Search of Missing Persons joined forces with the volunteers during this recent operation, lending institutional support and resources to the search. Additionally, state and municipal authorities deployed security personnel to the search site, establishing a protective perimeter for the workers and volunteers as they combed the area.
Back in Arizona, the investigation into Guthrie’s disappearance has seen little advancement since February. Authorities from the Pima County Sheriff’s Office had previously suggested that Guthrie was deliberately targeted by someone familiar with her household, operating under the belief that her family possessed considerable wealth. An alert was issued for a kidnapping suspect detected within seven miles of Guthrie’s home, but no charges have been filed, and no individual has been taken into custody in connection with the case.
With no arrests, a lack of confirmed leads on the U.S. side, and the investigation now extending into foreign territory based on an unverified anonymous tip, the case of the missing 84-year-old grandmother remains one of the most closely watched missing persons investigations in the country. The cross-border nature of the search underscores the complex challenges faced by authorities and volunteer organizations in resolving such cases, particularly when they involve international boundaries and unconfirmed information.
