The Pima County Sheriff's Department on Thursday said it has not been contacted by Mexican authorities amid news reports that an anonymous tip had prompted a search effort for Nancy Guthrie south of the border.
Ramona Guadalupe Ayala Ortiz, head of Buscando Corazones Nogales in Sonora, Mexico, said the collective received a tip that a grave belonging to Guthrie, 84, may have been found.
The tipster said searchers could find a body matching Guthrie's description in the Mariposa area near Nogales, Sonora, Mexico, 12 News reported. Buscando Corazones Nogales works to locate people missing in Mexico.

BORDER PROTOCOLS AUTOMATICALLY TRIGGERED IN SEARCH FOR NANCY GUTHRIE, RETIRED AGENT SAYS
Guthrie vanished from her Tucson, Arizona, home in February. Authorities have said they believe she was abducted, but there is no evidence that she was taken across the southern border.
Doorbell camera video shows a masked man wearing gloves on the front steps of the home around the time of Guthrie's abduction. The footage also captured a masked individual creeping up to the home three weeks earlier.
Her back door was also propped open by the time police arrived hours later, prompting questions about whether more than one person was involved. Supposed ransom notes were sent to TMZ and local media, but no one has been arrested in connection with the case.
