FBI joins search for missing mother of Today show host Savannah Guthrie

The search for Nancy Guthrie, mother of Today show host Savannah Guthrie, continues urgently after her disappearance nearly 72 hours ago. Despite the involvement of the FBI and new unverified ransom notes, there are no solid leads or suspects. Concerns are heightened due to her need for life-saving medication. The community in Tucson is rallying with a candlelight service, while Savannah Guthrie remains in town, canceling her plans to host the Olympics opening ceremonies.
