Last year, Smart told "GMA" that her life was "great," but that she still feared her alleged kidnappers.
"I think that if they were to be released, I think they would come back and they would try to come back after me," she said. "And I don't think ... that any child or any human should ever be in danger of having that happen again."
At the time, Smart expressed hesitation about testifying against the pair.
"I don't think I really want to, but I don't want them getting back out," she said. "I don't want them ever out because I really, really believe that they wouldn't stop."
