Just thinking: I have seen cases where law enforcement will put out false information to try and draw out a killer. For example they may state they have information leading to a potential suspect and that they are getting closer to identifying a suspect. I have seen cases, though those were older cases where the police would enlist a newspaper reporter to put false information geared to drawing out the killer- letting the killer think they are closer to identifying that suspect than they are. When law enforcement comes out like they are now and indicating basically they are clueless, I think it gives the killer a whole lot of confidence.
