The Arnold Paole vampire report
An Austrian army commission's report, dated Belgrade, 26 January 1732, recorded exhumations of villagers at Medveđa and was reprinted across Europe.
Wikipedia gives the date of the report as 26 January 1732, written at Belgrade and signed by the five officers involved. Bitter Winter says the commission finished its on-site investigation quickly and delivered the report on 26 January 1732. This is the Flückinger report, titled "Visum et Repertum", printed at Nuremberg that year.
According to Bitter Winter, over a hundred newspaper pieces across Europe reviewed it, and many readers met the word "vampire" there for the first time.
A Scientific American blog describes the scene at Medveđa, Serbia, in January 1732. Of forty villagers exhumed one morning, thirteen were identified as vampires. The blog says fresh blood at the mouth or nose, or at stake wounds in the chest, was taken as proof.
"The report is dated 26 January 1732, Belgrade, and bears the signatures of the five officers involved."
