ST. LOUIS (AP) — A Missouri prosecutor on Wednesday filed a motion to vacate the conviction of a man imprisoned for more than three decades for the shooting death of a 15-year-old boy, the second time in two weeks that a St. Louis-area prosecutor has challenged a longstanding murder conviction.

Christopher Dunn, now 52, is serving life without parole for killing Ricco Rogers in 1990. St. Louis Circuit Attorney Gabe Gore said in a news release that the case against Dunn relied on testimony from a 12-year-old boy and another aged 14, both of whom later recanted.
