The nephew of former Chicago mayor Richard M. Daley and ex-White House Chief of Staff Bill Daley was charged Monday with involuntary manslaughter in the 2004 death of David Koschman.

According to the Chicago Tribune, a Cook County grand jury has indicted Richard J. "R.J." Vanecko and found that he "recklessly performed acts which were likely to cause death or great bodily harm to another," the indictment read.

The indictment was announced Monday afternoon by former U.S. attorney Dan Webb, a former U.S. Attorney. CBS Chicago reports that Webb began looking into Koschman's death and city and county officials' investigation into the matter eight months ago.

Koschman died following a single punch that knocked him to the sidewalk during a drunken altercation on a street in the city's Gold Coast district on April 25, 2004. He was 21 at the time of the incident. Vanecko, then 29, fled the scene after the incident.

Terence Gillespie, Vanecko's attorney, has maintained his client's innocence and denied allegations that political clout influenced the investigation into Koschman's death, NBC Chicago notes.

Koschman's death had been a cold case prior to an inquiry directed by the Cook County Circuit Court earlier this year, ABC Chicago reports. An inquiry into how the city and county investigated the case -- and possibly suppressed or concealed evidence -- "continues at a vigorous pace," Webb told CBS.

Vanecko, who now lives in California, will be arraigned on Dec. 10. His bond was set at $100,000.
