The Assassination of Bill Fisk was Wilson Fisk's retaliation against his father. After another fight between his parents, Bill and Marlene Fisk, resulted in Bill beating his wife, Wilson stepped in, smashing his father's head in with a hammer.
Bill Fisk loses his campaign for the Third District Council. Later, he is told by his son that a young man named Bernie Walker was knocking down the signs for his campaign and calling both of them losers. Fisk takes his son to confront the bully. Once they find him, Fisk asks Walker why he was hitting the signs and insulting him. Walker replied that he was only repeating his father's statements. Fisk then beats Walker with a bat and orders his own son to kick him and not stop.

Later that night, Bill Fisk told Wilson to sit in a corner and stare at a wall to make him think about his future. As Fisk was about to leave to talk with Don Rigoletto, he is stopped by his wife. Having been drinking, Fisk begins to beat his wife, with Wilson listening. Having occurred numerous times before, Wilson gets tired of these beatings and finally decides to put an end to them. He grabs a nearby hammer and repeatedly hits his father over the head with it, killing him.
Wilson and his mother cut up Fisk's body and spent the next week dumping his body parts into a river. All who knew that Fisk owed Don Rigoletto's money assumed that Fisk had left town to avoid him. Marlene then send her son to live with relatives on a farm.
