Savannah Guthrie has issued another emotional public appeal as the search for her mother, 84-year-old Nancy Guthrie, stretches close to six months. In a video released Monday, the "Today" show host said her family is still living through what she described as an unending nightmare since her mother vanished on Feb. 1.

According to the details shared publicly, Nancy Guthrie disappeared from her home just outside Tucson, Arizona. Savannah Guthrie directed her message at anyone responsible or anyone who may know what happened, pleading for information about where her mother can be found.

The new video marks the latest effort by the journalist to keep attention on the case. She said her family will never stop looking for Nancy Guthrie, underscoring how deeply the disappearance has affected those closest to her.

With the Savannah Guthrie plea in the Nancy Guthrie Tucson case, the family is once again trying to bring renewed focus to an elderly missing-person case that has remained unresolved since early February.
