Did Daley nephew Vanecko confess to fatal punch?

The Chicago Sun-Times reports:

A nephew of then-Mayor Richard M. Daley “may have made an admission of guilt” to detectives that he threw the punch that caused David Koschman’s death, attorneys for Koschman’s family said in a court filing Wednesday.

They said sworn witness statements to the city of Chicago inspector general’s office, which they obtained under a court order, contradict arguments made by Cook County State’s Attorney Anita Alvarez. Alvarez is fighting their efforts to have a special prosecutor appointed to reinvestigate the case and determine whether her office and the police are guilty of “official misconduct.”

Minutes after four of Koschman’s friends were unable to identify Daley nephew Richard J. “R.J.” Vanecko in a police lineup nearly eight years ago, the friends say an unidentified detective told them the police knew who had punched the 21-year-old from Mount Prospect in the face, according to their sworn statements, which Alvarez unsuccessfully tried to keep from being released.

Just imagine, the Cook County Republican party couldn't even field a candidate to run against Anita Alvarez. Just a reminder: Anita Alvarez doesn't think you should be able to own a handgun!
