Legal Question in Criminal Law in Illinois

Unlawful entry.

I will assume that you did not leave out any important details for example,(a dead body hanging out of the window of your house) when the police went inside.Police cannot without a warrant enter a private home and search or seize a person or property absent exigent circumstances and reasonable belief that a crime was committed.Please furnish additional information as to why they entered your home. How did they know it was your home, did they search the home, arrest someone or confiscate property? Please note that police can search the immediate area incident to a lawful arrest. Do you have a pending case? I would need more information to give a definitive answer on whether the police actions were unlawful, although at first glance they would appear to be.
