Special Prosecutor Dan Webb’s file on the David Koschman case is in the hands of the FBI.
The Sun-Times obtained a court document in which Webb says he turned over all his evidence on the case to the feds in June.
Last month R.J. Vanecko, a nephew of former Mayor Rich Daley, plead guilty to throwing the punch that led to Koschman’s death in 2004.
He is serving 60 days in jail for involuntary manslaughter.
In his report, Webb said he was unable to charge police and state’s attorneys despite evidence they botched the Koschman investigation, including losing case files and fabricating a defense for Vanecko.
But Webb indicates some of the officers may be under investigation by the FBI for similar conduct in other cases.
