Elizabeth Smart was 14 years old when she was kidnapped at knifepoint from her Salt Lake City home. For nine months, she survived on hope.

“[The key to my survival] was truly the belief that my family would love me no matter what and that my family would want me back, no matter what,” the 37-year-old told Fox News Digital. “Maybe nobody else, but my family would. That was worth doing whatever it took to survive.”

Today, Smart is a married mother of three, but her story is far from over. She is a child safety activist who regularly speaks on behalf of missing and exploited children. She’s also partnering with “America’s Most Wanted” to serve as a guest speaker for Monday’s episode of “America’s Most Wanted: Missing Persons.”

“It makes me sound slightly neurotic, which I suppose I probably am, truth be told,” she said. “But these are my children. I would rather double, triple, quadruple check — no — keep eyes on them [at all times] to ensure their safety than ever look back and have regrets that I didn’t take it seriously enough.”

Smart continues to hope. This time, she’s hopeful that “America’s Most Wanted: Missing Persons” will help raise awareness for families in need.

“These families deserve answers,” she said. “They deserve to be reunited with their loved ones. And I just know that if these stories had the same amount of attention that my story did, we would see a lot of people coming home. We would see a lot more happy endings.”
