Albert Fish held the genuine belief that the murders he committed were upon instruction from God. Peter Stumpp, who started practicing the "wicked arts" from 12 years of age, was convinced he was a werewolf. There are many more murderous individuals like them. Supernatural Serial Killers explores the association between serial killers and the supernatural. The crimes committed by these men and women usually involved sexual deviance, cannibalism, and violence toward children. In 16th-century Europe, the problem became so significant that "werewolf witch trials" were conducted. Many have no idea that it was possible to be tried and convicted for the crime of being a werewolf, but lycanthropy was a serious and major social concern in the 1500s. In this book, approximately 20 supernatural serial killers are discussed, including their backgrounds, crimes, trials, and defenses.
