Police in Fond du Lac, Wisconsin, arrested a man who claimed to be a werewolf:
39 year old Robert Marsh, recently released from jail, now returned, was charged with disorderly conduct, criminal damage to property, and criminal trespass. He also had a bag of weed on him; technically this story, then, does not fall in the category of "narcozoology", but rather an even more obscure science: narco-cryptozoology.
Police reported that Marsh spoke to them in "what sounded like a medieval sounding language." Since this occurred in Wisconsin, Marsh is fortunate that he didn't break into the apartment of a sword-wielding RenFaire freak.
And, once again, since it is Wisconsin, we should be grateful that the werewolf inside Robert Marsh's head wasn't a necrophiliac.
