A St. Louis judge on Tuesday will hear arguments as to why the 1991 murder conviction of Chris Dunn should be vacated. Dunn has spent more than 30 years in prison. Two witnesses who identified him as the killer have recanted and two St. Louis prosecutors, Kim Gardner and Gabe Gore, believe that he is innocent. After Gore announced earlier this spring he would file a motion to vacate Dunn’s conviction, producer Danny Wicentowski spoke with Dunn from the South Central Correctional Center in Licking, Missouri, about his reaction.
