The Cressi Sorcerers were said to have the ability to shapeshift into wolves.
The Cressi Werewolf case took place in France, in the village of Cressi. Five sorcerers were put on trial in 1604 where the five admitted to witchcraft, sorcery, and shape-shifting into wolves to attend Sabbats. They kidnapped a boy, took him to one of the rituals, drank his blood, and killed him. They confessed to offering the boy to the devil, cut up his body, cooked him, and ate him. They said that they saved his fat for some potions and ointment. The five were burned to death.
