Another Eviction Question - Illinois?

No lease agreement, just a verbal one. My tenant still owes me for last month's utilities and rent and this month's utilities and rent, now up to $700 and the cable was transfered to this house in his name and it's not working either. He has told me for the last week that he will be giving me money; even interrupting my dinner last night with a call asking if I would take cash since he cannot seem to find any checks. He didn't come home with the money, said he was going out later to get it, I inquired twice more last night and the last time he just went to sleep or at least in his room and didn't respond. He also leaves my house a general mess and I have absolutely no reason to keep him around if he's not paying rent. I plan on calling the Police later to ask them what routes I can take if I do actually plan to remove him, but the thing that worries me is that the family's got a good lawyer friend that I fear will turned on me if I try removing him with no contract.
