CHICAGO -- She inspired a novel and a movie starring Robert Redford when in 1949 she lured a major league ballplayer she'd never met into a hotel room with a cryptic note and shot him, nearly killing him.
After the headlines faded, Ruth Ann Steinhagen did something else just as surprising: She disappeared into obscurity, living a quiet life unnoticed in Chicago until now, more than a half-century later, when news broke that she had died three months earlier.
The Cook County medical examiner's office confirmed Friday that Steinhagen passed away of natural causes on Dec. 29, at the age of 83. First reported by the Chicago Tribune last week, her identity was a surprise even to the morgue employees who knew about the 1984 movie "The Natural," in which she was portrayed by actress Barbara Hershey.
"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, wrote in an email Sunday.
The story began with what appeared to be just another young woman's crush on Eddie Waitkus, the Chicago Cubs' handsome first baseman.
After the 1948 season, Waitkus was traded to the Philadelphia Phillies. "When he went to the Phillies, that's when she decided to kill him," Theodore said in an interview.
Steinhagen had her chance the next season, when the Phillies came to Chicago to play the Cubs at Wrigley Field. She checked into a room at the Edgewater Beach Hotel where he was staying and invited him to her room.
"We're not acquainted, but I have something of importance to speak to you about," she wrote in a note to him after a game on June 14, 1949.
It worked. Waitkus arrived at her room. After he sat down, Steinhagen walked to a closet, said, "I have a surprise for you," then turned with the rifle she had hidden there and shot him in the chest.
A judge determined she was insane and committed her to a mental hospital. She was released three years later.
Details about the rest of her life are sketchy. She lived with her sister in a house just a few miles from the hotel where she shot Waitkus.
Waitkus, who played the season after he was shot, decided not to press charges.
He died in 1972, 12 years before Redford portrayed Roy Hobbs, the character inspired by Waitkus.
