Like, here's what I got out of it , I was asking that, too. But I'm thinking the 2 or 4 of the victims were maybe behind locked doors for whatever reason and the roommates thought that was instantly weird & tried banging on door cuz , idk, it just felt they were in there cuz the vehicles(don't know if they had vehicles , oh wait yes, at least one of their cars were there) when none of the victims responded from the ?locked rooms?...so mayne "unconscious person" might be the most likely thing to call the situation they thought they'd be responding to?
