I'm not an Illinois lawyer, but my research suggests that involuntary manslaughter is a Class 3 felony, which has a sentence of 2 to 5 years, although "aggravating circumstances" can raise this crime to a Class 2 felony, which brings 7 to 14 years in jail.
Criminal sentencing takes a number of things into account, in most cases, and different states handle this in different ways. For reliable advice, based on the facts of your case, you need to talk to an attorney in your area.
