Savannah Guthrie returns to 'Today'

Guthrie fought back tears as she thanked viewers for their support while investigators continue to search for the 84-year-old.

The case has seen little progress recently, though TMZ reports that new ransom notes have been sent claiming her mother is alive in Mexico and demanding cryptocurrency.

Local authorities and the FBI are reviewing all tips, but no suspects have been named in the suspected kidnapping.

Guthrie's return to the anchor desk marks a difficult personal milestone as she balances her public role with the ongoing family crisis.
