Cook County prosecutors on Thursday told a judge they would try to bring other “crimes and bad acts” into a felony case against a Chicago police commander.

Glenn Evans, photographed on his way out of the hearing by Charlie Billups for WBEZ, allegedly jammed his gun into an arrested man’s mouth last year, pressed a taser to his crotch and threatened his life. Last month Evans pleaded not guilty to nine counts of aggravated battery and official misconduct.

During his 28 years in the police department, Evans has drawn at least 52 brutality complaints. Two led to 15-day suspensions from duty. Six others have led to federal lawsuits that the city paid to settle.

Evans’ attorney, Laura Morask, calls that history irrelevant. She says what matters are the allegations in the case’s indictment, which focuses on the incident last year.

The commander, meanwhile, is trying to find out how a DNA report in the case went public. Morask is demanding records from WBEZ and the Independent Police Review Authority, one of several government entities that had the report. At the hearing, Morask said the records would show bias on the part of the case’s investigators.

The judge, Rosemary Grant Higgins, pushed back. She said she would hear more from all sides but warned, “It’s not this court’s job to plug leaks or interfere with the press.”
