A volunteer organization dedicated to locating missing persons in Mexico mobilized near the U.S.-Mexico border after an anonymous source claimed the elderly mother of a prominent television personality had been laid to rest in an unmarked grave somewhere in the region.
The tip landed Wednesday with Buscando Corazones Nogales, a Nogales-based collective led by Ramona Guadalupe Ayala Ortiz, pointing searchers toward terrain that sits more than 70 miles from where 84-year-old Nancy Guthrie was last seen alive.
Guthrie — mother of NBC “Today” show anchor Savannah Guthrie — was taken from her Catalina Foothills home in Tucson, Arizona during the early morning hours of February 1, setting off an investigation that has stretched across months without producing a single arrest.
The anonymous caller directed the collective to a stretch of land known as Mariposa, the Spanish word for butterfly, positioned northwest of the border city of Nogales — well south of the Arizona neighborhood where the grandmother vanished.
Whoever placed the call described a grave near a stream somewhere within that zone, offering coordinates specific enough to send the team into the field almost immediately.
“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.
Search teams pushed further into the Mariposa terrain during this operation than they had during any prior mission, penetrating sections of land that had not previously been examined.
The area is no stranger to grim discoveries — Buscando Corazones Nogales previously recovered 25 unmarked graves from within that same stretch of ground during earlier operations this year.
Despite the depth of Wednesday’s search and the detailed nature of the tip that triggered it, the team returned without locating any evidence connected to Guthrie.
The setback did not halt the group’s commitment to the mission. Ayala Ortiz confirmed the collective intends to mount additional search operations across the Mariposa zone, pursuing both Guthrie and any other unidentified individuals who may be buried there.
The Sonora State Commission for the Search of Missing Persons joined forces with the volunteers during the operation, lending institutional weight to what began as a tip from an unknown source.
State and municipal authorities deployed security personnel to the search site, providing a protective perimeter around the workers and volunteers combing the area.
Back in Arizona, the investigation into Guthrie’s disappearance has advanced little since February. Authorities have previously suggested she was deliberately targeted by someone familiar with her household who believed the family held considerable wealth.
The Pima County Sheriff’s Office issued an alert for a kidnapping suspect detected within seven miles of Guthrie’s home, though no charges have followed and no individual has been taken into custody.
With no arrests, no confirmed leads, and a search now extending into foreign soil, the case of the missing 84-year-old grandmother remains one of the most closely watched missing persons investigations in the country.
