My question involves criminal law for the state of: Illinois
im 17 years old,I went to tTer GAt to steal something and opened the item (Less than 20$)(Around 15$) i put it in my pocket and started to go. I figured to buy something so that it wont be obvious. So i bought something but as i was going up to pay for the item, i noticed someone dressed in regular clothes with a walki and my empty box that i stashed. So i decided to walk back and dump the items stolen. he quickly followed after me and i think he found the items. So i went up to pay for that item, freaking out (At this point had nothing on me stolen) i paid for the item i originally had but my problem was that i paid for some of it with my credit card and rest gift card. As im paying, i hear him on the walkie asking for the address of the store. After paying, I walk out, not looking nervous and act casual and just walk out. No chasing, no running, no cops. They did not come after me, nor did they arrest/make me sign papers. I am still nervous thought because of my credit card transaction, and my license plate. Any ideas what they can do?
