"I believe he played a huge role in his death," she said about the teenager.
"He could have ... When George confronted him, and he could have walked away and gone home. He didn't have to do whatever he did and come back and be in a fight," she said.
The juror had no doubt that Zimmerman feared for his life.
She said she didn't have a strong impression of Martin.
"All we really heard about Trayvon was the phone call that he had, and the evidence they had found on him. We basically had no information what kind of a boy Trayvon was, what he did. We knew where he went to school and that was pretty much about it, and he lived in Miami," she said.
Asked about what role race might have played in the trial, which grew into a national debate about gun laws and race in America, the juror said it did not matter.
Zimmerman did not target Martin, who was African-American, because of the color of his skin, she said.
The juror believes he profiled him because of the suspicious way he acted.
"I don't think race had anything to do with this trial. I mean just because he was black and George was Spanish or Puerto Rican, I don't think it had anything to do with this trial. But I think people are looking for things to make race play a part," the juror said.
She added that she hopes Zimmerman will be able to move on.
"I hope he gets some peace," she said. "I hope his family can live a normal life after a while. I don't know how he's ever gonna do that, but I hope he can. He'll never forget, but I hope he can."
