I found Cian's body on the roof along with Ryouka. Cian's body was badly bruised and she had multiple broken ribs. The bruising was mostly on the front of her body, I didn't see much bruising in the back. There were no other injuries. I wasn't able to tell what object was used to do the damage.

There was a note in her pocket, but Ryouka took it before I could read it.
