Murphy says the assailant never faced justice in her case, but eventually went to jail for another case.
"Until today, only a few have heard my story. Now you all know," she said. "Surely among us is a woman who has been silenced by her own story. I know the feeling of shame, I know the feeling of helplessness, and I know the disappointment of justice denied. But by speaking out, we can find our strength, and ensure that our lives are not defined by this experience."
She says she is sharing her story to encourage other victims of sexual violence to speak up.
