Calvin Duncan was wrongfully convicted and imprisoned for 28 years for a murder he did not commit. Calvin was freed on January 7, 2011, and was exonerated on August 21, 2021. During his wrongful imprisonment in Louisiana State Penitentiary at Angola, Calvin worked as an inmate counsel substitute, providing legal assistance to hundreds of imprisoned men. Calvin helped to secure a new trial for a well-known prison journalist, Wilbert Rideau, and initiated the litigation that culminated in an important Brady case from the U.S. Supreme Court, Smith v. Cain. Calvin was instrumental in securing the U.S. Supreme Court decision in Ramos v. Louisiana that convictions by non-unanimous jury verdicts were unconstitutional. In 2013, Calvin was awarded the Open Society Foundation’s Soros Justice Fellowship and became the founding director of the Light of Justice Program, which provides assistance to incarcerated individuals to overcome procedural barriers in post-conviction. Calvin is a co-creator of the Visiting Room Project that shares stories of people sentenced to life without parole.
