A twelve-year-old boy who disappears from Derry in July 1958. Beverly Marsh witnesses him being killed by mutant leeches. Patrick is a little overweight and has a round face, “as pale as cream.” Patrick is a psychopath who, when he is five, kills his infant brother, Avery. In school, he has the habit of killing flies and keeping them in his pencil box. He also supposedly kills cats and dogs and keeps them in a refrigerator. He joins in with Henry Bowers, Victor Criss, and “Moose” Sadler in bullying and beating Eddie Kaspbrak, who later sees Patrick’s body decomposing in the sewer.
