Dan K. Webb, a former U.S. Attorney, was appointed Monday as special prosecutor to look into the death of David Koschman.

Cook County Judge Michael Toomin appointed Webb to investigate the 2004 brawl involving Richard Venecko and that led to Koschman’s death a short time later.

Koschman’s family asked for a special prosecutor alleging Venecko was not charged in the death because he is the nephew of former Chicago Mayor Richard M. Daley.

Webb has been tasked with investigating if anyone should face criminal charges in the case. He will also look into any possible misconduct by the prosecutors and police that handled the initial investigation.

Webb said he would start working on the case immediately. He said the first step was “to gather all records to get up to speed on the facts and then the investigation will take us where the facts take us.”

In approving the request for a special prosecutor, Judge Toomin determined there was enough evidence of a conflict of interest in the original investigation to warrant a further look.

Asked by reporters whether he has any connections to former Mayor Daley, Webb said he was not connected with any of the parties involved in the case.

“I intend to fairly investigate it [the case] as I’ve done throughout my career,” said Webb.

Meanwhile, Locke Bowman, an attorney representing Koschman’s family, said he was satisfied with the selection of Webb as special prosecutor.

“We have said all along that we want a full, vigorous investigation of this matter,” said Bowman.

There is no date yet for when the investigation will be completed.
