An anonymous tip claiming that missing Arizona woman Nancy Guthrie may have been buried in an unmarked grave in northern Mexico prompted a search operation this week, but investigators and volunteers did not locate any evidence connected to the case, as reported [1] by the New York Post.
The search was conducted by Buscando Corazones Nogales, a volunteer organization that assists in locating missing persons in Mexico.
According to the group’s leader, Ramona Guadalupe Ayala Ortiz, the organization received an anonymous call on Wednesday alleging that Guthrie’s remains could be found in a remote area near the U.S.-Mexico border.

Guthrie, 84, disappeared from her home in Tucson, Arizona, on Feb. 1. Authorities believe she was abducted from her residence in the Catalina Foothills, and the investigation into her disappearance remains active.
No arrests have been announced, and investigators have not publicly identified any suspects.
According to Ayala Ortiz, the anonymous caller provided a specific location in an area known as Mariposa, northwest of Nogales, Sonora. The tipster allegedly claimed Guthrie had been buried in a grave located near a stream.
“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 Mexican newspaper El Imparcial.
The information prompted volunteers and search personnel to travel to the area and conduct an initial search.
Mariposa has previously been the site of discoveries involving unmarked graves. Earlier this year, search teams working in the region located 25 such graves, making the latest tip significant enough to warrant further investigation.
During the operation, volunteers expanded their search deeper into the area than previous efforts. Despite the extensive examination of the terrain identified by the caller, no evidence connected to Guthrie was discovered.

Ayala Ortiz said the search did not produce any findings related to the missing Arizona woman.
Although the tip did not lead to a breakthrough, the organization indicated it intends to continue searching the region in future operations.
The effort was supported by the Sonora State Commission for the Search of Missing Persons, which assisted in coordinating resources for the operation.
Municipal and state authorities also provided security for volunteers and personnel participating in the search.
The case continues to attract attention on both sides of the border due to Guthrie’s connection to NBC “Today” co-host Savannah Guthrie.
Nancy Guthrie disappeared during the early morning hours of Feb. 1 from her Tucson-area residence, more than 70 miles north of Nogales.
Investigators have spent months pursuing leads and conducting searches, but authorities have released few details about the status of the investigation.
Law enforcement officials have previously stated they believe Guthrie was taken from her home, but no public announcements regarding arrests or major developments have followed.
The latest search illustrates how tips—both confirmed and unconfirmed—continue to generate investigative activity as authorities and volunteer groups seek answers in the case.
While the anonymous report ultimately did not lead to the discovery of Guthrie, search organizations involved in the effort said they remain committed to following credible leads and continuing operations aimed at locating missing persons throughout the region.
For now, the mystery surrounding Nancy Guthrie’s disappearance remains unresolved, and investigators continue urging anyone with information about her whereabouts to come forward.
