Leigh Brackett was the Sheriff of the police department of Haddonfield Illinois on Halloween in 1978 when Michael Myers began his killing spree. Brackett agreed to help out Michael Myers’ doctor Sam Loomis when Myers broke out of the sanitarium 15 years after killing his sister.
Brackett ends up a little more effected by Myers’ reign of terror than he knows in the first film. His daughter Annie was friends with Laurie Strode (although she always kind of treated her like shit) and is actually the first person that Myers kills in Haddonfield. If was a better cop his daughter probably would’ve lived. What a dumbass. He has to stop pursuing the killer after he finds out that his daughter is among the people who were killed.
