Evidence of vampire burials continues to surface in Poland. Experts who recently excavated a 16th century grave in a small town in northwestern Poland say the body bore signs of an unusual ritual. According to CNN, the teeth had been removed, a rock inserted in the mouth and the leg had a stake through it. Last summer, Polish archaeologists discovered the remains of four headless skeletons at a construction site. Scholars say the gruesome burials reflect the medieval fear of vampires in the region.
