I know I am late, but I thought it was obvious the older girl was feeding rats to zombies. She was the one that talked to Nick (the zombie wearing the mechanics jumpsuit), and treating him as a living human or possibly a pet, and thus feeding him fits with that. From there it is kind of a strange jump, but I assume they will make her the one that is mutilating the animals around the prison. I do not know if she killed the adults. Either way they needed to be killed and burned.
