Michael Myers was raised in the small, mid-west town of Haddonfield, Illinois. At age 6 Michael murdered his oldest sister, Judith on Halloween night. It was always unknown why he killed her; or why he spared his baby sister... After being locked up in Smith's Grove Mental Hospital, Michael escapes on October 30 and head home to Haddonfield. At least, that's where his psychologist, Dr. Sam Loomis assumes he is going. Michael, who is now 21, returns home and bides his time. That night he tracks down his baby sister, Laurie Strode (who has been adopted and is oblivious to her violent roots) and proceeds to murder 2 of her friends. He pursues her that entire night (which continues on in Halloween II) but eventually fails. Over the next twenty-four years, Michael killed and killed, believing that his sister Laurie is dead (car crash). He even kills his niece and any person who is attached the Myers/Strode families and anyone who stands in his way. He finally realized Laurie wasn't dead and caught up with on the twentieth anniversary of their original encounter (Halloween: H20). Laurie escaped that event under the impression she'd finished her brother...until four years later when he caught up with her and killed her. It is unknown what became of Michael after Halloween: Resurrection.
