The Innocence Project was co-founded by Barry Scheck, J.D., a defense lawyer who became known through the 1995 murder trial of former professional football player O.J. Simpson. The project also paved the way for similar programs to be founded throughout the United States. Today there are 68 of them. And thanks to the efforts of these programs, 271 prisoners have been exonerated through DNA testing, 17 of whom were scheduled to be executed, and the actual perpetrators were identified in 120 of these cases.
