TUCSON, Ariz. — Savannah Guthrie is renewing pleas to neighbors and residents of Tucson, Arizona, to jog their memories in hopes of generating new leads in the disappearance of her mother, Nancy Guthrie, who was reported missing on February 1.

The co-host of the 'Today Show' took to Instagram to express gratitude to the community, stating that the family believes someone may hold vital information regarding the case. They urged community members to go through their memories of events from January 31 to February 1 and the evening of January 11.

Someone knows something. It’s possible a member of this community has information that they do not even realize is significant, the family’s statement reads. They encourage everyone to consult camera footage, journal notes, text messages, or conversations for any relevant details, emphasizing that “no detail is too small.”

In a somber recognition, the family also acknowledged that Nancy Guthrie, 84, might no longer be alive. The FBI has released surveillance video showing a masked individual near their home on the night of her disappearance.

The Guthrie family has set a $1 million reward for any information that leads to their mother’s recovery. Savannah also made her first off-screen visit to the 'Today' show studio on March 5 since her mother went missing, focusing her energies on finding Nancy while her former colleague Hoda Kotb filled in for her on the morning show.

Nancy Guthrie’s disappearance is notable in the affluent Catalina Foothills area where she lived, which is known for its picturesque hiking trails. The family continues to seek public assistance while holding on to the hope of finding Nancy.
