CHICAGO (AP) — The nephew of former Chicago Mayor Richard Daley has pleaded not guilty to involuntary manslaughter in the 2004 death of a suburban Chicago man whose family suggested there was a police cover-up in the initial investigation into the fatal fight.

Richard Vanecko, 38, was arraigned during a brief court appearance Monday morning.

Last week, Vanecko was indicted by a Cook County special grand jury in the death of David Koschman of Mount Prospect. Koschman died days after he fell and struck his head during a fight with Vanecko outside a bar in Chicago's Gold Coast neighborhood.
