Since 1973, 123 innocent persons awaiting execution in 25 states have been exonerated and released from death row. A list of these individuals, in chronological order of exoneration, is available from the Death Penalty Information Center at < www.deathpenaltyinfo.org/ >. Exoneree number 80 on this list is Ron Williamson, whose strange and tragic tale is told in John Grisham’s first nonfiction book, The Innocent Man: Murder and Injustice in a Small Town (Doubleday, New York, 2006). (At a separate trial conducted a week before Williamson’s, a friend of his, Dennis Leon Fritz, another innocent person, was also erroneously convicted of the same murder as Williamson but received a life sentence rather than death. After almost 12 years in prison, Fritz, like Williamson, was exonerated by DNA and released.)
