Overview
- Nancy Guthrie, 84, disappeared from her Tucson home on Feb. 1 and Pima County with FBI help treats the case as an abduction and homicide investigation.
- Volunteer searchers in Sonora, Mexico, acting on anonymous tips reported uncovering 25 unmarked graves in the Nogales/Mariposa area but have not linked any remains to Guthrie.
- Sonora officials have asked the Guthrie family for DNA to allow comparisons, and Mexican authorities have not formally coordinated all tips directly with Pima County, sheriff’s officials say.
- Investigators say ongoing lab work, including DNA processing at federal labs and digital‑forensic analysis, is driving a cautious public pace while retired agents press for release of enhanced images of the masked 'porch guy' and unverified photos circulate online.
- A $1 million family reward and a $100,000 FBI reward remain open, and a person tied to ransom‑style messages to the family is scheduled for federal proceedings on June 23 without any confirmed link to Guthrie’s disappearance.
