Congratulations, you avoided making a critical mistake that could have hurt you. I am always amazed when people voluntarily admit crimes to the police, making their job easier and their attorney's job much more difficult.
At this point, you don't have to do anything. You might want to talk to your roommate and see what happened. If you are contacted by anyone, don't give information and tell the police you won't answer any questions or make any statements without your attorney present. Then ask for your lawyer. Then don't say anything.
If you are subsequently charged with a crime, contact a few criminal defense attorneys and schedule some consultations. Bring along any documentation you might receive and be honest and open with the attorneys you speak with.
