Overview
- Nancy Guthrie, 84, vanished from her Tucson home during the night of Jan. 31–Feb. 1, and investigators treat the case as an abduction after signs of a struggle were found.
- Volunteer group Buscando Corazones Nogales searched areas near Nogales, Sonora after anonymous tips and uncovered 25 unmarked graves but reported no remains matched Guthrie.
- Leaders of the Sonora searches requested that the Guthrie family provide DNA samples so Mexican forensic teams can compare recovered remains to the family profile.
- Pima County and the FBI say the multiagency investigation remains active; officials have released doorbell images and confirmed Nancy’s blood at the scene while forensic testing continues and no arrests have been announced.
- A $1 million family reward and an FBI reward have produced many tips and public scrutiny, and investigators face cross-border coordination and lab-processing delays that will shape the next steps in the probe.
