Witnesses question accounts of homicide case tied to Daley nephew, says Sun-Times.
The police reports also attribute statements to friends of [the deceased David] Koschman and to a bystander described by prosecutors as one of the two unbiased witnesses that they say they didnt make or that distort what they told detectives.
Koschmans friends recently told the police theyd be willing to take lie-detector tests.
Instead, the Police Department closed the recently reopened case on March 1 without seeking criminal charges. The police concluded that the 6-foot-3, 230-pound Vanecko threw the punch that knocked the 5-foot-5, 140-pound Koschman to the street, where he struck his head, causing a brain injury that killed him 11 days later but that Vanecko acted in self-defense. They reached that conclusion without speaking to Vanecko, who they say ran away afterward and has refused to speak with detectives.
