As the reports regarding the anonymous tip began circulating online, the Pima County Sheriff’s Department, which has been carrying out the investigation in the case in coordination with the FBI, responded to the reports, said it had not been approached by Mexican authorities.“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 began. “The investigation remains active and ongoing, and we will continue to follow up on any credible information.”What did Mexican search group say about Nancy Guthrie’s alleged grave?According to newspaper El Imparcial, the leader of the Nogales collective, which is dedicated to locating missing persons and uncovering clandestine graves, claimed that they received an anonymous call informing them that the 84-year-old woman had been buried in one of the streams in the area known as Mariposa , which is located west of Nogales and near the border strip with Arizona.“We received an anonymous call telling us that the woman’s remains were in the Mariposa area in a grave over a stream, and this time we came to explore this stream that we failed to explore in the first intervention,” Ayala Ortiz was quoted as saying by the Spanish newspaper loosely translated to English.
