Victims were often killed by having their throats torn out. The Kingdom of France used a considerable amount of wealth and manpower to hunt the animals responsible, including the resources of several nobles, soldiers, royal huntsmen, and civilians. The number of victims differs according to the source.
A 1987 study estimated there had been 610 attacks, resulting in 500 deaths and 49 injuries; 98 of the victims killed were partly eaten. Other sources claim the animal or animals killed between 60 and 100 adults and children and injured more than 30. The beast was reported killed several times before the attacks finally stopped.
