Sheriff in Nancy Guthrie Case Says Authorities ‘Do Believe Something Occurred’ on Specific Date Before Disappearance

Investigators probing the abduction of 84-year-old Nancy Guthrie are narrowing their focus on a specific date weeks prior to her disappearance, citing new digital forensic evidence.

Pima County Sheriff Chris Nanos confirmed to local media that January 11 has emerged as a critical window in the ongoing search for Guthrie, the mother of Today show co-anchor Savannah Guthrie. While the sheriff stopped short of detailing specific evidence, he attributed the renewed interest to sophisticated digital analysis conducted by the FBI.

The focus on January 11 follows a period of technical conflicting reports regarding surveillance footage. Initial data provided by Google—which owns the Nest security system at the Guthrie residence—suggested a suspect was captured on camera without a backpack on that date.

Though Google later clarified it could not “confirm” the exact date of the image, Sheriff Nanos maintains that the FBI’s analysis of electronic equipment suggests significant activity occurred.

“We do believe that something occurred on Jan. 11,” Nanos told KOLD Tucson. “That’s with the FBI’s analysis of the equipment and digital stuff they’ve done.”

Nancy Guthrie was taken from her Tucson home in the early morning hours of February 1. Despite the passage of nearly two months and a $1 million reward offered by the Guthrie family, authorities have not officially named a suspect or established a clear motive.

The investigation currently centers on two distinct timelines:

• January 11: Identified via digital forensics as a period of potential surveillance or related activity.
• January 31 – February 1: The window immediately surrounding the abduction.

The Guthrie family has intensified their plea for public assistance, specifically asking residents to review any personal security footage or memories from the late evening of January 11.

Sheriff Nanos characterized the current lead as “speculative” but promising, noting that the department is currently processing a vast amount of evidence. “We have so much in front of us,” Nanos stated. “Anything is possible, but we’re not giving up.”

The FBI continues to provide technical and investigative support to the Pima County Sheriff’s Department. No arrests have been made, and the case remains classified as an active abduction.
