Zouhary discovered the boys' confessions contained different accounts of the crimes, from the chronology to their own nicknames.
Katie Marie Zouhary: They get the framework right, but they don't get the details right. And if any two of them had gotten the details right that would be one thing, But when you look at each of these confession line-by-line in the way we did. It's pretty glaring that there is no cohesive story here.
Last year, based on the new DNA evidence, and Katie Marie's work the courts vacated the convictions and granted all of them certificates of innocence which restored their full rights as U.S. citizens.
As for Anita Alvarez, she's still not convinced Terrill Swift and his co-defendants are innocent.
Anita Alvarez: I don't know whether he committed the crime or not. There are still unanswered questions in both of these cases. That I couldn't sit here today and tell you that they are all guilty or they are all innocent.
Byron Pitts: What would you say to her if you could?
Terrill Swift: I was wrongfully incarcerated for 15 years and you're still fighting my innocence, not only mine but my co-defendants. What else needs to be done?
During our interview, Terrill's mother, who was in the room at the time, became emotional.
Byron Pitts: I could hear you crying over there. Why are you still shedding tears?
Mrs. Swift: That was hard. Actually have your child taken away from you. And he was innocent. And I knew this from the beginning, but what could I do? Not be able to get my child, my baby, my first born, that was hard and it still is. We came through it with the grace of God.
