- Arizona authorities are addressing an anonymous tip claiming to have information about the fate of Nancy Guthrie.

- The Pima County Sheriff's Department says it has not been contacted by Mexican authorities regarding a tip about an unmarked grave.

- Guthrie, the mother of *Today* anchor Savannah Guthrie, has been missing for more than four months.

Authorities in Arizona are weighing in on an anonymous tip claiming to have information about the fate of Nancy Guthrie, the missing mother of *Today* anchor Savannah Guthrie.

The Pima County Sheriff's Department said in a statement posted to social media Thursday, "We are aware of reports regarding an anonymous tip related to the Nancy Guthrie investigation that was provided to a group in Mexico. At this time, we have not been contacted by Mexican authorities."

The statement added, "This investigation remains active and ongoing, and we will continue to follow up on any credible information." The department declined to comment further.

The communiqué came after a volunteer organization that searches for missing people in Mexico — the Nogales-based Buscando Corazones collective — told *El Imparcial* that an anonymous caller had alleged that Guthrie's remains could be found buried near a stream in Mariposa, an area west of Nogales near the border with Arizona.

Group leader Ramona Guadalupe Ayala Ortiz told the publication that a search was conducted in the area but a grave was not found. She said the group would continue to search the area, adding that through searches from April to May alone, her organization discovered more than 25 unmarked graves containing the remains of at least 32 individuals in the Mariposa area.

Sheriff gives update on Nancy Guthrie investigation, says authorities believe they know the abductor's motive

Guthrie was reported missing from her home in the Catalina Foothills neighborhood of Tucson on Feb. 1. Footage of a potential suspect recovered from a doorbell camera the night her disappearance led investigators to begin treating the case as a kidnapping.

Working in conjunction with the FBI, the Pima County Sheriff's Department has continued to turn over new leads — from DNA evidence recovered at Nancy's home to a suspect and his mother being detained in connection with the case. But nothing credible or substantial has stuck after analysis and interrogation.

Sheriff Chris Nanos has faced criticism for his handling of the case. In March, an *Arizona Republic** *report uncovered misrepresentations in his stated work history, and FBI Director Kash Patel has repeatedly asserted that his agents were "not let in" to assist on the case for a number of days following the declaration of Guthrie as a missing person.

Earlier this month, Nanos gave an update on the search as it crossed into a fourth month."This is a very sensitive case, but what really makes it prolonged is we do rely on labs," he said, enumerating the logistical precautions in place to protect the integrity of analysis, that nevertheless slow the investigation down.

"Nobody wants to arrest the wrong person," he stated, adding hopefully, "We know somebody out there knows."
