New Tenant BIG Problem

[Matt Anderson]

I have a tenant that moved into a 4plex when the Cov-id issue first started.  She is refusing to pay the rent now. She and the boy friend, who is not on the lease and just moved in are causing problems with the other tenants. I pay for the water and electric on the 4plex as well. She at some point bought a pool (not a kiddy pool either) and filled it up with water from the property.  

How do you get rid of someone like this when the State of Illinois won't let you evict yet. The other tenants are wanting her gone as well. 

What do I do?  And yes she has a job and passed all of our screening requirements.
