Request filed in 2004 death involving Daley nephew

A published report says a suburban Chicago woman wants a special prosecutor to look into the 2004 death of her son who fell during an altercation with former Chicago Mayor Richard Daley’s nephew.

The Chicago Sun-Times reports that Nanci Koschman on Wednesday asked Chief Cook County Criminal Courts Judge Paul Biebel Jr. to appoint an independent prosecutor to investigate David Koschman’s death. The newspaper reports Richard Vanecko hit him in the face and he fell, hit his head and died days later.

According to the Sun-Times, police listed his death as an unsolved homicide until this year, when detectives closed it without seeking criminal charges.

Nanci Koschman alleges charges would have been filed against Vanecko if it weren’t for the Daley connection.

Vanecko’s attorney didn’t immediately return a message.
