There was a killer when they meet that was very active at that time but not any killer oh no a crazy a very crazy one they of course killed the catch? The police only find the blood no body they know who were the victims but the body nowhere to be found. But the killer always left notes where they talked about how was going their personal live. No trace is left behind finger prints nothing
