Nine months after her mother, Nancy Guthrie, was abducted from her Tucson, Arizona, home, "TODAY" co-host Savannah Guthrie has issued a new plea for information.

Guthrie shared an old drawing by her daughter, Vale, depicting a blue umbrella in the rain with the words, "I know it might not seem like it, but I really need my mommy." She wrote on Instagram that the drawing "says so much about how I feel."

"The world goes on, things appear ‘normal’ — as we try to keep going and be strong, especially for our young kids — but it’s not and it never will be," Guthrie said. She emphasized her family's pain, stating, "For Annie and Tommy, for Cam and Kristine, for Mike and me and for all of Mom’s beloved grandchildren: We ache for her, we cry out for answers, we cannot move forward."

Guthrie's family is offering a reward for information. "We need someone to help us, tell us what you know. Our mom was a light in this world. We want to celebrate her and give her the dignity she deserves. The reward is still available. Please. We are begging you. Please help us," she implored.

Nancy Guthrie, 84, was reported missing on February 1, having last been seen at her home shortly before 10 p.m. on January 31. Authorities believe she was taken against her will. Security footage from the home's doorbell camera showed an individual tampering with the device while masked and armed.

The FBI and the Pima County Sheriff’s Department have not identified suspects or made arrests. The Pima County Sheriff’s Department stated that the Nancy Guthrie Task Force is continuing to work with laboratories on DNA analysis and recently met with scientists to explore advancements in the case. The agency reiterated that no tip is too small.

In July, authorities released two ransom notes. The first, sent February 2, demanded $4 million in bitcoin for Nancy Guthrie's release, stating she was safe. A second note, sent four days later, claimed she had died shortly after her abduction. Investigators noted distinctive writing patterns in the notes and appealed to the public for any recognition of the style.

Guthrie has continued to host "TODAY" while searching for her mother, previously stating in June that the situation is "always with me." She described crying every morning on her way to work and every evening on her way home.

Anyone with information regarding Nancy Guthrie's disappearance is asked to contact the FBI at 1-800-CALL-FBI or submit an anonymous tip to the Pima County Sheriff’s Department at 520-882-7463.
