From National Geographic:
A female "vampire" unearthed in a mass grave near Venice, Italy, may have been accused of wearing another evil hat: a witch's.
The 16th-century woman was discovered among medieval plague victims in 2006. Her jaw had been forced open by a brick—an exorcism technique used on suspected vampires in Europe at the time.
At the height of the European witch-hunts, between A.D. 1550 and 1650, more than 100,000 people were tried as witches and 60,000 were executed—the vast majority of them old women.
