Jerry Bellwood was one of the many young victims who was killed in the horror novel, It.
He was in the fifth grade and also a classmate of John Feury (another victim of IT who was killed a few days later following Bellwood's death).
He was believed to have been murdered by IT (most likely disguised as Pennywise the clown) on mid-May of 1985. Not long after, the Derry officials discovered his mutilated corpse near Kansas Street. Using Bellwood's blood, IT presumably wrote "COME HOME COME HOME COME HOME" on a nearby concrete wall (as a clear message to Mike Hanlon and the rest of the Losers).
