That experience was the basis for her the best-selling book and award-winning film Dead Man Walking starring Susan Sarandon and Sean Penn. Throughout her work with inmates, she’s also turned some of her focus to the treatment of exonerees and the wrongly accused, an issue we’ve been following as part of our series “The Exoneree Diaries” by Alison Flowers. Sister Helen Prejean shares details of the people she’s met through her work.
