Petar Blagojevich - Vampire
The son told the villagers. Two nights later Petar returned but his son refused to feed him without an explanation for his being, you know, not dead. Visibly enraged but still wordless, Petar left. Again, the son reported the strange events to his neighbors. One day later, Petar's son was found dead. Over the course of the next week or so seven more villagers were found dead or dying. Many reported being visited by an angry Petar who grabbed them by the throat and choked them.
Terrified villages appealed to a local magistrate named Frombald. He and a priest exhumed Petar's grave. They found a corpse in excellent condition, apparently well fed. His eyes were open and appeared alive. There was fresh blood around his mouth. Most chilling, Petar appeared to be softly breathing. Panicked, they drove a stake into his heart which caused an explosion of fresh blood to flow. They then burned the corpse to ashes.
Fritz Haarmann - Vampire of Hannover
When Haarmann confessed he said he hadn't intended to kill anyone but that in "sexual ecstasy" he would bite them in the throat ripping out the larynx. After killing them, he would dismember them, remove their organs, strip off their flesh, and decapitate them; disposing of the remains in the forest by the river. Haarmann claimed to have killed ten boys and young men a year since the end of the Great War. He was convicted of killing 24 and, in a bit of macabre irony, was executed by beheading.
Gilles Garnier - Werewolf
Felicia Felix-Mentor - Zombie
According to scholars, a bokor, Voodoo priest, can make a zombie by drugging him with tetrodotoxin, simulating death.The bokor would dig up his victim who had been awake but paralyzed during the funeral and burial. The victim would thus believe he had died and been revived as a zombie. Additional drugs to suppress inhibitions and free will keep the victim a willing slave.
Skeptics will point out that Petar Blagojevich's vampire corpse was the result of normal putrefaction. Firtz Haarmann was simply a sexual sadist psychopath. Gilles Garnier was mentally ill and his confession was directed by the interrogation tactic of the day, torture. And Felicia Felix-Mentor was not a long lost beloved family member returned but simply a totally different mentally ill woman.
