I'm still invisible?

So I found out my killer is indeed on the sister dorm. Most likely 27-3 since there's only 1 person I know that's still alive from South Tower.

And my killer did talk to my roommate and told him I'm impossible to find? Bruh, I spent so much time sitting around doing nothing in public areas. How did you not find me?

Narrowed my lists of possibilities down to 11. I need more information, or just more girls to die to thin out the herd.
