Scientists continue to investigate both a centuries-old killing spree and modern-day sightings.Court records and sketches from the 18th century depict an unbelievable case. A creature that slays like an animal, but acts like a human. Could it be a werewolf? Why were some of the bodies found without any clothes? Why were some decapitated? A biotechnologist is testing whether the severity of the attacks could in any way be indicative of who - or what - carried them out. In Lemgo, historian Dr. Utz Anhalt is investigating a case involving a convicted werewolf. Meanwhile, cryptozoologist Ken Gerhard is looking into an alleged encounter with a werewolf in the US. Vivid reports detailing the sightings give historical insight into the origins of this terrifying beast.
