Detective Fitzsimmons was a detective who was sent to investigate Marion Chambers's house after it was broken into and she, along with Jimmy Howell and Tony Allegre were murdered. He and Matt Sampson discussed the possiblity that it was Michael Myers who was behind the breakout and murders. Sampson was at disbelief that it was Myers and assumed that he was too old to still be doing these crimes. Fitzsimmons however told Sampson that Myers was younger then he was as Fitzsimmons was fifteen years old when Michael killed his sister Judith Myers. Fearing that it was indeed Michael, Fitzsimmons decided to call Haddonfield just as a precaution as the next day was Halloween.
