His nephew killed a man

And that wasn’t Vanecko’s first altercation, he was involved in a brawl at Daley’s Grand Beach, Michigan summer home where someone was hit in the head with a baseball bat. He pled guilty to a misdemeanor in that case.
He got a sweet plea deal for manslaughter for killing Koschman, and served his 60 day sentence in McHenry county jail, not Cook county jail. If that were me or you, we would still be in prison. A lot of detectives retired before they could face discipline because of how they “botched” that case.
