Serial Slaughter is the story of the infamous Zodiac Killer. The killer roamed California, especially Northern California for decades. He announced himself with dramatic flair corresponding with Law Enforcement and the media in order to gain the attention he craved. "This is the Zodiac Speaking" & "This is the murderer of the 2 teenagers last Christmas at Lake Herman & the girl on the 4th of July." Making sure they knew his kills, connecting the dots for them. Fading away as promised in 1969, he continued to kill & ceased to "help" those who would hunt him. Details now included are new. The crimes are looked at, thoroughly researched, investigated, and written about with a new perspective. Great new finds of information at last to add to the story. The cases of murdered women and girls are brought back to the surface as the author works to bring attention once again to their cases.
