Elmo Blatch

Elmo Blatch is a villain from the book and 1994 movie, The Shawshank Redemption. Despite appearing only briefly, he plays an extremely important role in the story. He is the real killer of Andy Dufresne's wife and lover, which is the crime Andy was imprisoned for. Due to the fact that Andy does not bother to clear his name after his escape from Shawshank Prison, Blatch presumably got away with the crime.
