They need Steven Hansen on the case
The police of Salem, Massachusetts are obviously tapped out creatively. What else would be their reasoning for naming a murderer whose calling card is drawings of bells, the pun-deficient "Bell Killer?" Seriously, not even a single "For Whom The Bell Tolls" or "Dead Ringer" thrown in for good measure.
Maybe I haven't gotten around to reading Brittany "Punching Wallaby" Vincent's Murdered: Soul Suspect review yet, but I'll assume that the 4.5 score comes from the suspect lack of puns.
