Savannah Guthrie has returned to NBC’s “Today” show anchor desk for the first time since her mother's disappearance more than two months ago. Guthrie said “it is good to be home.” Guthrie has acknowledged being a changed person a little over a week ago. She also says it’s hard to go forward not knowing what happened to her mother. There has been no sign of the 84-year-old Nancy Guthrie since she was reported missing from her Arizona home on Feb. 1. Authorities continue to believe she was abducted in the middle of the night. But they have not released any new evidence in weeks.
