We begin with the abc news exclusive. The first juror to comeforward, to show her face, to reveal what was going through her mind as they tried to decide whether or not george zimmerman was guilty of murder. That juror one-on-one with abc's robin roberts, offering revealing words about her own struggle in that jury room. This was her seat, front left, her eyes trained on the witnesses. Tonight hear for the first time what she thinks about george zimmerman. She begins by revealing her first vote in those deliberations. What was your first vote sfl? My first vote was second-degree murder. Second-degree murder? In between that nine hours, it was hard. You know, a lot of us that wanted to find something that, something that we could connect to the law. For myself, he's guilty because the evidence shows he's guilty. He's guilty of? Killing trayvon martin. But as the law was read to me, if you have no proof that he killed him intentionally, you can't find -- you can't say he's guilty. Did you want to step out at all? Did you want to? I was the juror that was gonna give them the hung jury. Oh, I was. I fought to the end. It's hard for me to sleep. It's hard for me to eat. Because I feel that I was forcefully included in trayvon martin's death, and as I carry him on my back, I'm hurting as much as trayvon martin's mother, because there's no way that any mother should feel that pain. But you feel in your heart of hearts that you and the jury approached it and came with the decision, and you stand by that decision to this day? I stand by the decision because of the law. If I stand by the decision because of my heart, he would have been guilty. I know that you've heard some people have said point blank, they've said, george zimmerman got away with murder. How do you respond to those people that say that? George zimmerman -- look, george zimmerman got away with murder. But you can't get away from god. And at the end of the day, he's gonna have a lot of questions and answers he has to deal with. The law couldn't prove it. But, you know, the world goes in circles. Our thanks to robin roberts. I want to bring in "nightline" anchor dan abrams. We were here that night and you said to me, it will be very revealing when we hear from a juror who weighs in on the man in that courtroom, versus the law. This is what the defense feared, some of the jurors might decide the case based on emotion, and not based on the law. Even she said, she said she still thinks he did the right thing, because he followed the law, if she followed her heart, she would have hung that jury. She even said she would give them the hung jury, I fought to the end. So there was debate. There was debate. They asked for the manslaughter charge read back. If there had been one or two maddies back there, it could have been a hung jury. Tomorrow morning rob oin "good morning america" weighing in on that torn juror, struggling with the heart break, but standing by the verdict. The exclusive on "good morning america."
