Kidnapping survivor and advocate Elizabeth Smart says she believes Nancy Guthrie, the 84-year-old mother of "Today" show co-anchor Savannah Guthrie, could still be found alive, offering a message of continued hope more than six months into one of the country's most closely watched missing-person investigations.

Nancy Guthrie was last seen at her home in Tucson, Arizona's Catalina Foothills neighborhood on the night of January 31, and was reported missing the following day. Doorbell camera footage from her home captured images of a masked individual, whom investigators and the public have since referred to as "Porch Guy," though no suspect has been publicly identified and the case remains unsolved.

Smart, who survived a nine-month abduction as a 14-year-old in 2002, has repeatedly weighed in on the case in the months since Guthrie went missing, offering a perspective shaped by her own experience being held captive before her eventual rescue.
