 The murder victim is based on notorious Chicago Cubs fan Steve  Bartman. Bartman was vilified by many people after he interfered  with Cubs outfielder Moises Alou, who was trying to catch a foul  ball in game six of the 2003 National League Championship Series.  The Cubs were winning the game at the time, but eventually lost.  Many Cubs fans blame Bartmans actions for the Cubs losing the game  and not reaching the World Series.
