Elizabeth Smart still has hope that Savannah Guthrie's 84-year-old mother, Nancy Guthrie, could be alive more than three months after going missing in Arizona. "She could absolutely still be alive," Smart, 38, told CNN on Tuesday, May 5. "There are cases that span many more years than mine does and they came back alive. And we're talking years and years. So she could absolutely still be alive." The former ABC News commentator has personal experience to draw from when discussing the Guthrie case.
