My question involves criminal law for the state of: Michigan
Me and my roommate are both 18 and in college and he brought a fridge to our room from home that be both share. About a week ago he and a friend decided they wanted to buy alcohol (I had no part in deciding to) and went to get some. I didn't go with them, nor did I give them any money for it. Two days after his friend's sister bought it for them, they spent the night in our room and drank about half of it (I didn't drink any or ask to).
Recently I found two cops waiting for me by my door saying someone had reported it, either seeing it in the fridge or seeing my roommate drinking it.
Though it is his fridge and alcohol he bought, the cop told me that because I keep fruit and water in the fridge that means I have access to it.
Am I in any sort of trouble for not reporting it or just for sharing the place it was housed?
