Nancy Guthrie disappearance probe widens with Mexican grave search and kidnapping suspect review

Nancy Guthrie, an 84‑year‑old Tucson resident and mother of NBC Today co‑anchor Savannah Guthrie, vanished from her home on February 1, 2026. The case quickly became a no‑body murder investigation, with the FBI and Pima County Sheriff’s Department gathering blood evidence, security footage of a masked figure, and noting the absence of her heart medication. Authorities have offered a $1 million reward for information.

In June, a Mexican volunteer group, Buscando Corazones, acted on an anonymous tip and excavated a suspected shallow grave near Nogales, Sonora, in the Mariposa area west of the border. The search yielded no remains, but it highlighted the cross‑border flow of leads and the challenges of jurisdiction.

Separately, retired homicide detectives explained why investigators also examined Coral Michelle Smith, a kidnapping suspect whose alleged crime occurred less than seven miles from Guthrie’s home. While officials stress there is no evidence linking Smith to the disappearance, reviewing nearby criminal activity is standard practice in complex missing‑person cases.

The investigation remains active, with law enforcement continuing to pursue leads and families awaiting answers.
