A Cary man twice convicted of attempted murder in Cook County, and acquitted of murder as a teen in 1980, has turned himself in after being wanted on a sixth alleged offense of drunk driving. Gnewuch turned himself in to McHenry County jail at about 5 a.m. Thursday, the jail log shows. According to court records, Gnewuch’s past DUI offenses occurred in Cook County in 1984, 1985, 1991, 2003 and 2004. Because he was a juvenile, he initially was taken into custody at a Lake County juvenile detention center and later transported to the McHenry County jail and tried as an adult. “It’s clear that this is a man who has not learned from his previous convictions,” McHenry County State’s Attorney Randi Freese said in a news release.
