What are the rules on writing realistic fiction based on true events? Do you have to change the names of all the people? Can you use direct quotes from trials or newspapers? If so, do they have to be cited and how? Some serial killers or murders are given certain names by the people e.g., Łucjan Staniak - aka The Red Spider and The Red Ripper, Władysław Mazurkiewicz - aka The Gentleman Killer, or the more commonly known, Vincent Johnson - aka the Brooklyn Strangler. Is it possible to use these titles as story titles or to include them in the story without citation if they are given by the general public?
