claimed to have exorcised and destroyed a whole nest of vampires in the area. In January 2005, rumours circulated that an attacker had bitten a number of people in Birmingham, England, fuelling concerns about a vampire roaming the streets. Local police stated that no such crime had been reported and that the case appears to be an urban legend. The chupacabra ("goat-sucker") of Puerto Rico and Mexico is said to be a creature that feeds upon the flesh or drinks the blood of domesticated animals, leading some to consider it a kind of vampire. The "chupacabra hysteria" was frequently associated with deep economic and political crises, particularly during the mid-1990s. In Europe, where much of the vampire folklore originates, the vampire is usually considered a fictitious being; many communities may have embraced the revenant for economic purposes. In some cases, especially in small localities, beliefs are still rampant and sightings or claims of vampire attacks occur frequently. In Romania during February 2004, several relatives of Toma Petre feared that he had become a vampire. They dug up his corpse, tore out his heart, burned it, and mixed the ashes with water in order to drink it. Origins of vampire beliefs Commentators have offered many theories for the origins of vampire beliefs and related mass hysteria. Everything ranging from premature burial to the early ignorance of the body's decomposition cycle after death has been cited as the cause for the belief in vampires. Pathology Decomposition Author Paul Barber stated that belief in vampires resulted from people of pre-industrial societies attempting to explain the natural, but to them inexplicable, process of death and decomposition. People sometimes suspected vampirism when a cadaver did not look as they thought a normal corpse should when disinterred. Rates of decomposition vary depending on temperature and soil composition, and many of the signs are little known. This has led vampire hunters to mistakenly conclude that a dead body had not decomposed at all or to interpret signs of decomposition as signs of continued life. Corpses swell as gases from decomposition accumulate in the torso and the increased pressure forces blood to ooze from the nose and mouth. This causes the body to look "plump", "well-fed", and "ruddy"—changes that are all the more striking if the person was pale or thin in life.
