evidence: R. Kelly avoids lengthy add-on to 30-year prison sentence CHICAGO (AP) — A federal judge on Thursday rejected a call from prosecutors to keep R. Kelly behind bars until he is 100, instead telling the Grammy Award-winning R&B singer he would serve all but one of his 20 years on child sex convictions simultaneously with a previous sentence. [...] The U.S. Attorney in Chicago, John Lausch, conceded that prosecutors were disappointed Kelly didn’t receive more consecutive prison time. But he added, "Twenty years is a significant sentence, and we are happy that that was imposed in this case."
