Continuity mistake: In the scene after the fake skeleton breaks through the wall Donna puts her mahogany coloured top back on. In a few seconds she kneels down to pick up her camera equipment from the floor without anything with her, but seconds later, when she grabs her camera gear, she has the small camera attached to her ear. (00:53:15)
Continuity mistake: Just before Jen gets her head sliced off, Michael Myers raises the knife and you can see on the knife there is no blood on it, even after killing Bill with it. (01:01:10)
Continuity mistake: The second after Jen gets her head sliced off you see her body is still standing but in the next shot when you see her head rolling down the stairs her body is laying flat on the landing. (01:01:15)
Continuity mistake: When Jen's head is on the floor you see the view from her attached camera is facing Sara, Rudy and Jim but when you see Jen's head on the floor the camera is in a position where it is facing straight at the floor. (01:01:25)
Factual error: Michael Myers stabs the first two knives through Rudy - they are very small and not very strong knives, but they manage to hold Rudy's weight upon the door. (01:04:05)
Continuity mistake: When Michael Myers stabs the first two knives into Rudy and it goes through the door he gets the other one out of the drawer which is about three meters away but when he actually takes it out of the drawer and stabs it through him the drawer is like fifty centimeters away. (01:04:10)
Continuity mistake: In the scene when Rudy has the last last knife stabbed through him about fifteen centimeters of the blade go through the other side of the door. About fifteen seconds later from the fitted camera view you see Michael open the door and Rudy has a large, thick padding on his back. There is no way the knife could have gone that far through the other side of the door if the padding would have been that thick. (01:04:20)
Continuity mistake: When the third knife is stabbed through Rudy you see it come out of the other side of the door but you don't see any of the other two knives below it. (01:04:25)
Plot hole: When Michael kills Rudy all of his knives are now gone but when he chases Sara around the house he has another knife with blood on it. Where did he get the other knife from? (01:04:30)
Continuity mistake: When Sara escapes out of Michael Myers' bedroom window she looks over to the garage and when you see the crowd at the party and there are about thirty people but in a span of 30 seconds there are about twice as many in the room. (01:06:35 - 01:07:05)
Continuity mistake: After Sara runs out of Michael Myers' bedroom window, he slices the bottom of her leg. But when she climbs up the roof there are no wounds. (01:07:00)
Continuity mistake: Near the end, Sara tied a camera cord round Michael Myers's neck. Then, he throws Sara onto the bed and breaks the wooden panel beneath it. In the next second, you see it again completely undamaged. (01:09:50)
Audio problem: After Michael is hung by the camera cord Sara receives a message from her palm pilot saying, 'HE'S STILL ALIVE'. The palm pilot beeped before she got the message. (01:11:10)
Other mistake: When Freddy and Sara walk down the stairs after hanging Michael Myers with the camera cord, neither of them notices Jen's head lying on the floor. You'd think that they'd react in some way to this. (01:11:15)
Plot hole: After Freddy kicks Michael Myers out of the window he is caught up on the camera cord outside of Judith Myers' room, which is facing the front of the house. However, when Freddy and Sara leave her room they come from the opposite side to where her bedroom is, which is the side of the house. (01:11:15)
Continuity mistake: After Sara receives a message saying that Michael Myers is still alive on her palm pilot Michael Myers stabs Freddy in his left shoulder but when it cuts to the close ups of the blade in his shoulder it is in his right shoulder. (01:11:45)
Visible crew/equipment: Near the very end when Sara is walking through the tunnel in the house, the camera angle is in front of her. To the right, just for a split second, you can see someone's hand moving down very quickly. (01:12:50)
Revealing mistake: When Michael is hung from the window, an upwards shot reveals the top of the sound stage the Myers house was built in (top right corner). (01:13:42)
Continuity mistake: When Sara is hiding in the garage she throws the chainsaw at Michael Myers and he manages to keep standing up but after Sara falls on the floor with the electrical circuits on top of her you see Michael Myers lying flat on the floor. (01:15:25)
Revealing mistake: At the end of the film the garage is on fire and just before Freddy bursts through the door, there is a really quick close up shot of Deckard kicking down the door. (01:16:30)
Answer: We do not know what has become of him. Most likely he is just attending college, and Michael has yet to find him.
He got killed by Michael because the clown mentioned that he killed 4 students that attended Hillcrest Academy. But I don't know.
