After more than three months, the search for Savannah Guthrie's 84-year-old mom, Nancy, continues with no named suspects. Kidnapping and survivor advocate Elizabeth Smart was only 14 when she, like Nancy, was abducted from her home โ€“ and against all odds, lived to tell about it. Elizabeth tells CNN's Erin Burnett she believes Nancy may still be alive, citing her own kidnapping experience. The now-38-year-old was abused and held for nine months before she was rescued by police while walking on a Utah street with her captors.
