Author and researcher William H. Kennedy has compiled an impressively documented piece of work on satanic driven crimes in modern times. Begining with a brief history of Satanism in America in the 20th century. From Aleister Crowley [ The Great Beast] to Anton Levey, the Church of Scientology,the Process Church of the Final Judgment,Michael Aquino and the Temple of Set to other less known Satanic cults. He then moves on to the killers themselves. Much of the information contained is from the killers themselves. From Charles Manson to David Berkowitz [ Son of Sam ], Richard Ramirez [Night Stalker], Ricky Kasso, Varg Vikernes [ Death Metal Killer ], Eric Harris and Dylan Klebold [ Columbine Killers ], Jeff Weise and other cases. The main stream media seldoms makes a peep of the Satanic origins of any murders. And in fact the police and FBI are told to keep quiet on cases when evidence of Satanic cult murders take place . A very well researched and intresting,if not terrifing journey into the minds of truly possessed killers.
