Jim McCloskey was at a midlife crossroads when he met the man who would transform his life. Jorge de los Santos, a heroin addict who'd been convicted of murder years earlier swore to McCloskey that he was innocent—and, over time, McCloskey came to believe him. With no legal or investigative training to speak of, McCloskey threw himself into the man's case. Two years later, he successfully effected his exoneration. McCloskey had found his calling. He would go on to establish Centurion Ministries, the first group in America devoted to overturning wrongful convictions. Together with a team of forensic experts, lawyers, and volunteers—through tireless investigation and an unflagging dedication to justice—Centurion has freed 63 prisoners and counting. When Truth Is All You Have is McCloskey's inspirational story as well as the stories of the unjustly imprisoned for whom he has advocated.
