I know that we already know there are at least 2 killers but I think there are a ton of killers who are all taking advantage of having a serial killer around and using it to take out whoever really bothers them.

The ones I am sure are not one of the killers would be Denise Hemphill, Zayday Williams, Grace Gardner, Chad Radwell, Chanel No.3 & pretty sure not Hester Ulrich.

Also I think Gigi Caldwell is definitely in on the killings but I doubt she's committed a single one of the murders.

Definitely Oberlin
