The Pima County, Arizona, sheriff said Google has backed off from its initial report that a security image of a masked man at Guthrie’s front door was possibly from Jan. 11.Pima County, Arizona, Sheriff Chris Nanos has shared why investigators have been asking neighbors for video, specifically from Jan. 11, as the search for Nancy Guthrie enters its eighth week.

Neighbors near Guthrie’s home outside Tucson told NBC News on March 18 that investigators have visited their homes and asked about specific dates, primarily the weekend Nancy disappeared, as well as Jan. 11. The latter date is 20 days before police believe Guthrie, 84, the mother of the “TODAY” show’s Savannah Guthrie, was forcibly taken from her home. Her family reported her missing on Feb. 1.

Savannah Guthrie and her family also shared the Jan. 11 date in a message Saturday asking for the community’s continued support.

“We hope people search their memories, especially around the key timelines of Jan. 31 and the early morning hours of Feb.1, as well as the late evening of Jan. 11,” they said in a statement.

NBC News correspondent Liz Kreutz reported Monday on “TODAY” that she spoke with Nanos about the significance of Jan. 11.

He said Google initially told investigators that a security image of a masked man at Guthrie’s front door that was recovered from a Nest camera at her home was believed to be from Jan. 11.

However, Nanos said, Google then backed off that assertion.

“Google initially reported that date as a ‘possibility,’ then later retracted the statement,” he said.

The company told authorities it could not definitely determine that the security image was from Jan. 11 or any specific date, Nanos said. He maintained that remains unclear whether the suspect showed up to Guthrie’s home before the night she was abducted.

The FBI and Google have not commented on the timeline.

The Guthrie family put out a renewed call for help in a statement Saturday. Anyone with information is encouraged to call 1-800-CALL-FBI.

“We desperately ask this community for renewed attention to our mom’s case — please consult camera footage, journal notes, text messages, observations or conversations that in retrospect may hold significance,” the family said. “No detail is too small. It may be the key.”

“We miss our mom with every breath and we cannot be in peace until she is home. We cannot grieve; we can only ache and wonder. Our focus is solely on finding her and bringing her home. We want to celebrate her beautiful and courageous life. But we cannot do that until she is brought to a final place of rest.”
