The cops picked it up. They were stalling. That's why they won't release the note...it's too chilling.
Probably says the killer started it all when he snapped because he couldn't take the NJSC decision. His demand is that the Louse resign from the race, and the Torch forced to run. The PCers and Dems assigned to the case realize what that would cost them, and have decided that a few more dead bodies are an acceptable cost and the killer won't have any leverage or reason to kill in just a couple more weeks. This is why Chief Moose has decided to tough it out. Not much could be more chilling than that for this crowd.
