The persecution of the Jews in Zurich seems to be connected with the disappearance of a young boy. The son of Zurich man
Zur Wyden from a family of
shoemakers, about four years old, was murdered, and the Jews were accused of the murder. He was buried by his murderers in the
Wolfbach brook. A boy named Walther von Wyl treading the water on stilts found the dead body some time later. The Jews supposedly killed him with
nails, as he was "pushed [hammered] to death" (). They had taken his blood and then had buried him in the stream. The accused Jews were brought to court. Those declared guilty were burned to death, while their supposed accomplices were banished from Zurich. Because of lack of contemporary chronicles reporting the story of the murder of the child (which is first mentioned in written sources roughly two hundred years after the event) some modern historians doubt its veracity. ==The Massacre==
