Morris Creighton was the father of Jerome. He was decapitated.
One day, after arguing with Karen and Ms. Norris over an incident at the school in which Delia humiliated Jerome in front of their class, Morris returns to his car. As he is driving off, he accidentally drives into the lowered loading ramp of a lorry, decapitating him.
Morris believed that Delia was a troublesome kid, and called her a psychopath.
Morris threatened Gene because of Delia's behaviour towards Jerome, and regarded Gene as a "first-class jerk."
