Sister Helen Prejean is best known for her 1993 memoir, Dead Man Walking, about her role as a spiritual adviser to a convicted killer on death row. The story was adapted into an Oscar-winning film starring Susan Sarandon and Sean Penn. Prejean has accompanied six prisoners to their executions and has been at the forefront of activism against the death penalty.
Helen Prejean's book, "Dead Man Walking: An Eyewitness Account of the Death Penalty in the United States" (Random House) details her experience working with death row inmates in Louisiana. Prejean has come to believe that the death penalty is not only ineffective as a deterrent, but that the government can't be trusted to decide who should live and who should die. Prejean is a Roman Catholic nun.
