The words being bandied about that "he got away with murder" are Robin Robert's words not hers. Those words were part of the question being asked.
That being said she intended to make this a hung jury but was unable to because the other jurors more than likely called her out on it -- and she didn't like that.
When asked for reasons for her vote, she probably kept telling the other jurors "I just know in my heart that he's guilty" but they kept asking for reasons from the law and the evidence but she had none.
And this interview is her temper tantrum.
