A volunteer search operation has been launched in Mexico for Nancy Guthrie following an anonymous tip that claimed her grave had been located, according to reports.

The search effort was initiated after a group received the anonymous tip regarding the possible location of Guthrie's remains. Details about the specific location or the nature of the tip have not been disclosed.

However, the Pima County Sheriff's Department has stated that they have not been contacted by Mexican authorities regarding the search or the anonymous tip. This suggests a lack of official coordination between law enforcement agencies on both sides of the border.

The search appears to be primarily a volunteer-driven effort at this stage, though it remains unclear which organization or group is coordinating the operation in Mexico.

No additional details have been released about the credibility of the anonymous tip or whether any physical evidence has been discovered during the search efforts.
