Savannah Guthrie is honoring her mom in the most special way. This Sunday marks a heartbreaking reality for the Today host: it's her first Mother's Day without her mom Nancy Guthrie. As we've been following, the 84-year-old mysteriously vanished from her Tucson, Arizona home on February first and is believed by authorities to have been kidnapped. So, so heartbreaking. Savannah's hope for answers has never wavered, and on Sunday, she reiterated she "will never stop looking" for her missing mom.
