Suing bad tenants and their hangers-on in Illinois

[Jim Bryant]

I went through most of an eviction with a lousy tenant and they have vacated the premises.  I plan on getting the judgement in court for the eviction and I plan on suing them in small claims court for back rent, cleaning costs and some damages.  I realize these losers are probably not going to pay me, or it will be down the road.  That's fine, it's the principal of the thing.  Here's the question:

They had turned my house into some sort of loser inn and I was told by someone that they had up to 8 people living in this three bedroom house (originally just two people living there).  I have been able to piece together who was living there by some clues around the house.  Can I name these people in the suit as well, or just the renters?
