Squatter Tenant Finally Vacates Property - Question

[Raji Kaur]

I have a tenant in Chicago, who's lease expired months ago but she wouldn't move out and didn't pay rent, so I started the eviction process. I just learned that she did move out a couple of weeks ago but is not answering my calls or texts. Long story short, I just spoke to her new landlord who confirmed she moved in.  

I was told by an attorney before, that I couldn't kick her out or change the locks or enter the premises. That's why I started the legal process. But now that she's gone, do I still have those same restrictions? I hate to hire an attorney again and pay more for legal fees. Any input or feedback is greatly appreciated. Thanks.
