Legal Question in Landlord & Tenant Law in Illinois

Assuming the 3 girls chose each other as roommates and the landlord had nothing to do with putting the 3 girls together, this does not sound like it's the landlord's problem, but the landlord may be sympathetic and may agree to a situation where the offending roommate is replaced with someone else the other 2 girls know, especially if the charge results in a conviction, or may agree to allow your daughter out if she finds someone to replace her, but under the circumstances would someone else want to move in? If you want to be sure, however, have an attorney review the lease itself and see if there may be any other rights or remedies.
