A special prosecutor was appointed by a judge on April 23, 2012, to re-investigate the homicide of David Koschman, who died after allegedly being punched by a nephew of former Mayor Richard M. Daley in 2004. Nobody was ever criminally charged in the case. The special prosecutor — whose appointment was pushed by Koschman’s family, with legal wing support from the BGA — will explore whether there was a politically motivated cover-up within the Chicago Police Department and Cook County state’s attorney’s office.
