10 Most Evil Serial Killers

Serial killers have fascinated us since biblical times, but at the turn of the century the insanity and carnage of the postindustrial serial killer was unlike any other time in history.

In this fascinating - yet horrifying - expose, we explore the top 10, including cannibal Mark Jefferies, who murdered and ate his colleagues, as well as Andreas Bichel, the well-spoken fortune teller who would read his victims' fortunes before pushing in the knife. We visit the bizarre case of Romansanta, the man many believed to have been a werewolf, whose gruesome cadavers were found littered around a small Spanish town. And then there's Anna Maria Zwanziger, the Bavarian serial killer who poisoned her employers with arsenic and nursed them back to health to gain their favor. Edward H. Rulloff, a man who could speak 28 languages, poisoned his wife and children to death. There's also English prostitute Sarah Freeman, who loved to kill her own family members. And, last but not least, the man we all know today as Jack the Ripper, who terrified London for years with his brutal mutilations of prostitutes.

From poisoning victims to beating them to death, from disemboweling to cannibalism, and from evil gangs to twisted doctors, every way of taking life is explored, and no level of depravity is left untried. The world of the serial killer knows no bounds.
