Laurie Strode's son survived in the end of Halloween H2O. This was the last film of the series. However, remakes have been made since it.
Michael Myers didn't kill Laurie Strode in H20, he killed her in Halloween Resurrection.
In the original Halloween movie (1978), Laurie Strode did not have any children. Rather, she was babysitting for two children, Tommy and Lindsey. In later movies, we learned that Laurie strode had a daughter named Jamie. In Halloween H20 (1998), we met Laurie Strode's teenage son, John.
He played John Tate, the son of Laurie Strode/Keri Tate.
In Halloween H20 he kills people at the school Laurie Strode works at which was in California.
When it was reveled that she decapitated a paramedic she was sent to the sanitarium by officials who thought she was crazy.
In Halloween H20, Laurie Strode supposedly kills Michael Myers at the end of the movie by decapitating him with an axe. It is discovered in the next installment (Halloween: Resurrection) that she actually killed an ambulance driver, and that Michael Myers was still alive.
We never find out, after Halloween 6 the next movie was Halloween H20 which picked up the story of Laurie Strode, Halloween 4-6 were completely ignored.
At the end of Halloween H2O, Laurie Strode chops the killer's head off with an axe. However, it is revealed in a later movie that unbeknownst to anyone, Michael Myers switched places with a paramedic, and that Laurie cut off the paramedic's head and not that of Michael Myers.
Laurie Strode is Jamie's mother, Michael's little sister and his target in the original Halloween and Halloween II. Jamie Lee Curtis made it big so she didn't return to the franchise so they came up with her getting killed in a car accident. She returns in H20 which ignores Halloween 4-6 and her "death", she faked it and went into hiding after the events of the first two movies.
I think she finds out about it in Halloween 2 (1981). The audience finds out about it in Halloween 2, for sure, because it says so on the Wikipedia page. But it doesn't say whether or not this information is relayed to Laurie, and personally, I haven't seen Halloween 2 in so long (like, 12 years, or something) that I really can't remember any of it. She definitely knows about it in the next Halloween sequel that she was in, Halloween: H20 (1998), because I remember her talking about it, and I also remember that at the end, her fraternal feelings almost keep her from chopping Michael's head off. I haven't seen H20 in awhile, either (about 6 years), but I'm pretty sure she already knows about it at the very beginning of that one. I'm pretty sure she finds out in Halloween 2. I have included links to the Wikipedia entries for Halloween 2 and Halloween: H20.
He never died, he was in a coma; in the movie it seems the mention of his niece woke him up, but seeing as he never speaks he could have been awake for a while and just waiting for something to happen so he could escape.
Halloween H2O was released in 1998.
