Dead Man Walking is a work of non-fiction by Sister Helen Prejean, a Roman Catholic nun and one of the Sisters of Saint Joseph of Medaille.
Prejean has become a leading American advocate for the abolition of the death penalty. Her campaign began in New Orleans, Louisiana, in 1982, through a correspondence she maintained with two convicted murderers.
The first was Elmo Patrick Sonnier, who was sentenced to death by electrocution. She visited Sonnier in prison and agreed to be his spiritual advisor in the months leading up to his death.
