Brian
Brian Maxwell was the boyfriend of Heather Shyres and a minor character in Carrie.
He is first seen attending the prom and helps Chris' friends to cheat with the ballots. Heather then tells him to leave the prom when she notices the blood lifting from Carrie, but he doesn't take her warning seriously enough to leave the prom, when Carrie is gathering her strength.
During the massacre, Carrie uses her telekinetic powers to smash him in between the bleachers, killing him instantly.
