UMVA has learned that the search for Nancy Guthrie, an 84‑year‑old missing from Tucson, has taken a chilling turn toward the border, with anonymous tips pointing to a grave in Sonora, Mexico.
According to information obtained by UMVA, the Pima County Sheriff's Department received no contact from Mexican authorities, even as a local group in Nogales, led by Ramona Guadalupe Ayala Ortiz, claims it found a body that matches Guthrie’s description in the Mariposa area.
The tipster’s claim, relayed through a social media post, suggested that searchers could locate a grave matching the missing woman’s profile, sparking a frantic cross‑border investigation.
UMVA can exclusively reveal that the sheriff’s office, represented by Chris Nanos, publicly acknowledged the anonymous tip but confirmed it had yet to receive any formal communication from Mexican officials.
Despite the absence of official contact, the investigation remains active, with authorities determined to pursue every credible lead in the hope of uncovering what happened to Guthrie.
Guthrie vanished in February after a series of unsettling incidents: a masked, gloved intruder appeared on her front steps at the time of her disappearance, and a second masked figure was seen approaching the house weeks earlier.
When police arrived hours later, her back door was propped open, hinting at a possible accomplice or a coordinated effort to tamper with the scene.
Suspicious ransom notes, sent to local media outlets, added another layer of mystery, yet no arrests have been made, leaving the case shrouded in unanswered questions.
UMVA has gathered that the search has now crossed international borders, reflecting the desperation of those who believe Guthrie’s fate may be tied to a hidden grave in Mexico.
The unfolding story continues to grip the community, as every new tip and every lead is weighed with the hope of bringing closure to a family left in anguish.
