NBC has increased security measures around the Today show following the unexplained disappearance of co-host Savannah Guthrie's 84-year-old mother, Nancy Guthrie, from her Arizona home. The move comes amid an ongoing investigation treating the case as a possible kidnapping, with a $50,000 reward offered for leads. Former co-anchor Hoda Kotb returned to the program to offer support to Guthrie and her colleagues.
