A homicidal maniac was prowling the streets. The killer would attack unsuspecting victims in dark alleys and other places out of view of streetlamps and violently stab them to death. Then he would mutilate the corpse in abhorrent ways. Like so many other serial killers, this one preyed on the weak and defenseless. Homeless and down and out men were being targeted and no one could figure out why. The killer left each victim with a calling card, and a signature. Each body left in his wake had their genitals removed.
