TOMMY: When Carrie got soaked in pig's blood, the bucket fell on Tommy's head and knocked him unconscious. Ms. Collins and a group of students carry him off the stage but none of them are seen again after Ms. Collins death. In the epilogue, Sue's mother mentions his death.
NORMA: During the attack at the prom, a fire hose is released, spraying massive and powerful amounts of water onto everyone. The spray was so powerful that it knocked Norma against three tables, killing her almost instantly.
CHRIS: Chris and her boyfriend Billy escape from the school and drive off, but Carrie causes their car to crash, killing them both.
BILLY: See Chris.
MISS COLLINS: A basketball goal falls on Miss Collins, crushing her insides or possibly cutting her in half.
CARRIE: After setting fire to the school, Carrie returns home, is stabbed by her mother, and her telekinetic powers go out of control. She then locks herself and her mother in a closet and sets fire to their house. The final scene is a dream sequence in which Sue visits the empty lot where Carrie's house was. There is a For Sale sign in the shape of a cross with the words 'Carrie White burns in hell!' written across it. But as this was a dream sequence it's left a shade ambiguous, but likely she was killed.
MARGARET: When Carrie returns home from the prom, Margaret has resolved herself to the notion that Carrie is spawn of the devil and must die. As she hugs her sobbing daughter, Margaret stabs her in the back. Carrie retaliates by killing Margaret.
SUE: Sue, who snuck into the prom in time to see the prank that Chris and Billy had set up, was expelled from the gym by Miss Collins, who thought she was there to make trouble. Consequently, Sue was not in the gym when Carrie set it afire. However, the shock of watching the school go up in flames and seeing all of her friends die gave Sue many days and nights of bad dreams. It is Sue who, in the final scene dreams of visiting the vacant lot where Carries house was as if it was her grave.
OTHERS: Sue's mother confirms in the epilogue that many of Sue's friends died. Those who weren't knocked down by the water from the hose were running in panic before Carrie walked out after having set fire around most, if not the entire perimeter of the gym.
