Ruth Ann Steinhagen, whose shooting of Philadelphia Phillies first baseman Eddie Waitkus in 1949 inspired part of the novel "The Natural," died in Chicago at 83.
Steinhagen died in December.
She was 19 when she wrote a note to Waitkus, asking him to come to her hotel room. When he arrived, she shot him in the chest with a rifle, a scene repeated in "The Natural" when an obsessed woman shoots Roy Hobbs after luring him to her hotel room.
A judge determined that Steinhagen was insane and committed her to a mental hospital. She was released three years later and stayed out of the limelight.
"She chose to live in the shadows and she did a good job of it," John Theodore, an author who wrote a 2002 nonfiction book about the crime, told the Associated Press.
