 The panic began with an outbreak of alleged vampire attacks in East Prussia in 1721 and in the Habsburg Monarchy from 1725 to 1734 , which spread to other localities . Two famous vampire cases , the first to be officially recorded , involved the corpses of Petar Blagojevich and Arnold Paole from Serbia . Blagojevich was reported to have died at the age of 62 , but allegedly returned after his death asking his son for food . When the son refused , he was found dead the following day . Blagojevich supposedly returned and attacked some neighbours who died from loss of blood .
