Law and disorder in Lake County, Illinois

A North Chicago police officer has been charged with aggravated assault and aggravated battery after he allegedly pistol-whipped the living snot out of the Waukegan Police Chief. The incident occurred around 11 p.m. June 17 when off-duty North Chicago Police Officer Carl Sain went to his estranged wife's home in Waukegan. When nobody answered his knocking, he allegedly broke into the home and found off-duty Waukegan Police Chief Artis Yancey upstairs. Allegedly after punching out Chief Yancey, Office Sain then whacked the Chief repeatedly “upside his head” with a handgun. Chief Yancey was “messed up good,” suffering extensive facial injuries, including some broken facial bones. We are left to assume that Officer Sain objected to his estranged wife working undercover with Chief Yancey. CLICK HERE TO READ THE LAKE COUNTY NEWS-SUN STORY
