Savannah Guthrie shares heart-wrenching Mother’s Day post

(NBC, KYMA) - Savannah Guthrie has shared a heart-wrenching Mother's Day post, pleading for the public's help finding her mother, who has been missing for 99 days, as of Sunday.

The "Today" Show co-anchor posted a video compilation for Mother's Day sharing sweet moments of her mother, Nancy Guthrie.

It starts off with, "Mother, daughter, sister, Nonie - we miss you with every breath. We will never stop looking for you."

Savannah wrote, "We need help. Someone knows something that can make the difference. Call 1-800-CALL-FBI," reassuring the public that calls can be anonymous and the reward for information on her location is still available.

Guthrie, 84, was reported missing February 1 and was last seen at her home near Tucson, Arizona the night before.

There has been a massive search and nationwide concern for her well-being.

Authorities described the case as a possible kidnapping or abduction, but the Pima County Sheriff's Office has not publicly specified a motive.

The investigation into her mother's disappearance is ongoing. Anyone with information about the case is urged to contact 1-800-CALL-FBI or 88-CRIME.
