Authorities appeal for video footage as Nancy Guthrie search enters third week with no arrests

Authorities await DNA test results from pair of gloves found near home as search continues to draw national attention

The search for Nancy Guthrie, the 84-year-old mother of NBC's Today show anchor Savannah Guthrie, has entered its third week, as investigators ask neighbors within a two-mile radius to share home video footage and authorities await DNA test results from a pair of gloves found near the home.

Nancy Guthrie was last seen on the evening of 31 January, when she was dropped off at her home in the Catalina foothills north of Tucson, Arizona, after having dinner with her older daughter and son-in-law. She was reported missing the following day, after she failed to arrive at a friend's house to watch a church service.
