Savannah Guthrie and her siblings have issued a desperate plea to the Tucson, Arizona, community, begging neighbors to “search their memories” and security camera footage to help find their missing mother.

“It’s possible a member of this community has information that they do not even realize is significant,” the Today show host wrote in a new statement on Instagram. “We hope people search their memories, especially around the key timelines of January 31 and the early morning hours of February 1, as well as the late evening of January 11.”

“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 statement added. “No detail is too small. It may be the key.”

Nancy Guthrie disappeared from her home in the Catalina Foothills neighborhood outside of Tucson in the early hours of February 1, in what investigators believe was an abduction.

Drops of Nancy Guthrie’s blood were found on the front porch of her home, and the FBI released surveillance footage on February 10 that showed a masked man at her doorstep the night she went missing.

Authorities have shared little other evidence pointing to any suspects in the 84-year-old’s disappearance.

Nancy Guthrie’s children have previously appeared in videos pleading for her safe return, and have offered a $1 million reward for information leading to the recovery of their mother.

Her family’s most recent statement concluded with another emotional plea for Nancy Guthrie’s return home.

“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,” the statement said.

“We want to celebrate her beautiful and courageous life, but we cannot do that until she is brought to a final place of rest. Thank you for continuing to pray without ceasing,” the family continued.

The statement is signed “The Guthrie Family,” listing “Camron and Kristine, Annie and Tommaso, and Savannah and Michael.”

The statement was posted as the search for Nancy Guthrie enters its seventh week. It also comes as local news station News 4 Tucson aired a special “Bring Her Home — The Disappearance of Nancy Guthrie” on Saturday, to shine a light on the case.

As authorities continue their investigation, Pima County Sheriff Chris Nanos told NBC News earlier this month that investigators believe they have a motive for the kidnapping.

“We believe we know why [the kidnapper] did this and we believe that it was targeted, but we’re not 100 percent sure of that,” Nanos said. “I think day one, we had some strong beliefs about what happened, and those beliefs haven’t diminished,” he said on March 12.

The sheriff’s department and FBI have been analyzing DNA samples collected from Guthrie’s home and neighborhood, and have also been looking into the suspect seen in the doorbell footage.

However, authorities have shared no other information about where they are in their investigation or if they have any new leads.
