Christopher Dunn has spent 33 years in prison for a murder he has claimed from the outset that he didn't commit. St. Louis prosecutors are now convinced Dunn is telling the truth, but lawyers for the Missouri Attorney General's Office disagree and will argue for keeping him behind bars. Dunn was convicted of first-degree murder in the death of 15-year-old Ricco Rogers in 1990, based largely on the testimony of two boys who said they witnessed the shooting. The witnesses, ages 12 and 14 at the time, later recanted, claiming they were coerced by police and prosecutors. At an evidentiary hearing in 2020, Judge William Hickle agreed that a jury would likely find Dunn not guilty based on new evidence. But Hickle declined to exonerate Dunn, citing a 2016 Missouri Supreme Court ruling that only death row inmates - not those like Dunn sentenced to life in prison without the possibility of parole - could make a “freestanding” claim of actual innocence.
