When Sister Helen Prejean agreed to write to a convicted murderer on Louisiana’s death row in 1982, she had no idea what was coming. She would end up becoming his spiritual advisor, eventually accompanying him to his execution two years later. The experience changed her profoundly. She wrote a book about what she'd witnessed on death row, Dead Man Walking, which was turned into a major Hollywood movie in 1995. Forty years later, she has witnessed six more state executions - and is still tirelessly fighting to end them.
