Elwood Blatch is the man who really killed Andy Dufresne's wife and her lover. He appeared in Rita Hayworth and Shawshank Redemption and its film adaptation, The Shawshank Redemption.
Elwood would often brag about the crimes he committed to his cellmates in various prisons, as well as women he had slept with. One crime in partictular he would often talk about was when he got a job bussing tables at a country club. He would look at the regulars who came to the country club to see which one he could rob. He decided on golf pro Glenn Quinton, following him to his house one night. He entered the house and Glenn yelled at him. Elmo flew into a rage and drew his .38 special revolver, the muzzle of which he wrapped towels around to muffle the gunshots he used to murder Quinton and "this tasty bitch he was with". Because Andy Dufresne also owned a .38 caliber revolver, he was framed for the crime. One inmate he told his story to happened to be Tommy Williams, who later told Andy about it in Shawshank State Prison. Andy attempted to convince the warden of his innocence, but to no avail.
