Langdon, Illinois is a small town that appears to be the same size as Haddonfield, Illinois. This is where Marion Chambers had lived with Sam Loomis and stayed there even after Loomis' death. On October 29, 1998 the town was briefly infamous as Marion Chambers, Jimmy Howell and Tony Allegre were all murdered after a break in Marion's home. Detective Fitzsimmons believed that Michael Myers was behind the murders as the only thing that was missing in Marion's home was a file on Laurie Strode.
