The following events took place in the village of Tupanari in the district of Vlasenicki [to locate it on the map of Bosnia and Herzegovina simply go NE of Sarajevo]
An old peasant called Paja Tomic had died on the 9th of April 1923.
His wife Cvija complained that her dead husband returned to the house at night and had become a vampire. But apparently the widow wasn’t believed so quickly by the rest of the villagers and her nightmares continues for another full month until her sons Stevo and Krsto confirmed their father’s return from the grave.
The villagers gathered and decided that the vampire had to be destroyed so the dead man’s corpse was taken out of the grave, pierced with a hawthorn stake, and then cremated. The remaining bones were reburied.
Please take notice at the fact that we have a missing part here. We have no description of how the corpse was discovered upon unearthing. Usually we are given details and signs as to convince us that the deceased really was a vampire and that the villagers were in their right to proceed to the elimination of the undead.
In this case it seams that the family`s testimony was enough to get a “conviction”

NOTE: You will find a couple of other sites that give you details on this but I would like to make a clarification. The supposed vampire died in April of 1923! Some other authors give you the date of 23 May because that is when an article on the matter was published in a local newspaper.
The case can be found in “The Vampires: A casebook” by Alan Dundes and you may also find a transcript of the news article above mentioned.
