Mara Leveritt is an Arkansas journalist and author with whom you may already be familiar. She wrote the book Devil’s Knot that chronicles the story of the West Memphis Three, and which was subsequently made into a critically acclaimed movie.
She has recently written an article for the Daily Beast outlining her personal attempts to get the Arkansas Supreme Court to take some kind of action against a prosecutor who convicted, and sentenced to death, an innocent person by withholding evidence from the defense. Her efforts have so far been in vain.
