Bradley Trevor was a twelve year old boy who played baseball. Like Danny Torrance and Abra Stone, he also had the shining.
He was kidnapped by The True Knot, which resulted in him being brutally and graphically tortured to death by them in order to extract his steam. His body was then buried in a deep hole at an electricity plant, where he was killed.
His murder was witnessed by Abra Stone psychically, which traumatised her.
