I really like the idea of laurie being one of his victums that simply got away and he becomes obssesed with getting her. It would also be an interesting side story to where michael escapes once around the age of 15 and kills 2-3 people before being put back into smiths grove, then the state decides once he turns 18 they can put him to sleep legally. the night before hes to be transported to be executed he escapes smiths grove and returns to haddonfield.
I was actually thinking something more along the lines of patients in the juvenile ward at Smith's Grove suffer a series of mysterious "accidents", and always after some interaction with young Michael. Like in the comic, the day Michael arrives to Smith's Grove an older boy with psychotic tendancies tries to bully Michael. Next thing anyone knows he has a red crayon driven into his eye. Then Dr. Loomis decides to see how Michael responds to acts of kindness, so they throw him a birthday party. A fat kid grabs the birthday cake and starts stuffing his face with it. The next day the kid is found in the showers, badly burned. Seems someone had turned the water heater all the way to max, and turned the cold water off completely. The kid later dies of his injuries.
And as for your idea of him being put down at age 18 or whatever, first of all I don't think you can execute someone who is deemed psychologically incompetent (which is why the criminally insane are locked away and not executed). Secondly, I don't know if Illinois even has the death penalty (some states do, some don't). Third, if he were to have escaped and killed again when he was 15, the board of directors at Smith's Grove certainly wouldn't continue to keep him in a minimum security facility. They would shoot him up with the strongest tranquilizers money can buy and ship him off to a maximum security facility. Also, by keeping the deaths at Smith's Grove "mysterious accidents", you maintain the storyline from the original. That the staff at Smith's Grove had become lax in their security around Michael because they got used to his catatonic act. They thought he was a vegetable, so they didn't bother with retraints or sedatives. Only Dr. Loomis suspects the truth.
In the comic, Dr. Loomis isn't convinced of Michael's involvement in all the mysterious deaths and accidents until Halloween 1970. The staff throw a costume party for the kids in the juvenile ward. They give Michael a clown costume and one of those plain white masks to wear. The whole party Michael stands in the corner watching. The kids play musical chairs. The music stops and all the kids sit in a chair except for Michael. He wasn't even trying to win. One of the girls, who's dressed like a witch, laughs at Michael and says he has "cooties". There's a storm outside, which knocks the power out while the witch-girl is bobbing for apples. By the time the emergency generator kicks in, the girl is lying face down in the tub of apples, drowned. Michael is then shown sitting outside the administrator's office. Dr. Loomis is arguing with him, trying to convince him that Michael was to blame for the girl's death. While Loomis is in the administrator's office, the head nurse (who is also Dr. Loomis' fiance) is stalked by The Shape. When Loomis leaves the office, Michael is back sitting outside the office. Then someone finds the head nurse's body. Her head had been twisted almost all the way around. Both deaths are labeled "tragic accidents". But it's at this point that Dr. Loomis becomes convinced that there is no rehabilitation for Michael Myers. That the boy is just pure evil, and must be kept locked away, forever.
It was a very well written comic, and I think that it should be added to the movie script.
