An anonymous tip claimingNancy Guthrie‘s remains were buried in Mexico led to a massive search, but there’s still no sign of her … TMZ has learned.
Law enforcement sources tell us … it’s unclear who in Buscando Corazones Nogales — a volunteer group that searches for missing people — received the original anonymous tip that Nancy’s remains were in a shallow grave in Mexico.
FBI agents were not dispatched because they have no jurisdiction in Mexico … but Buscando Corazones Nogales searched. They have not found Nancy’s remains.
As we told you … BCN scrambled people to the area this week shortly after receiving the tip. Nancy has been missing since she was abducted from her Tucson home in early February … and Tucson is about 70 miles from the search area.
Photos showed BCN volunteers scouring the area for Nancy … working with an apparent police officer and taking photos among the trees.
The search group said it found over 25 unmarked graves during the search … but nothing related to Nancy.
