In 1980, after years of retirement, Lennon made a new album, "Double Fantasy", with his wife Yoko Ono. Chapman learned from a book where Lennon lived in New York City, and that it was not hard to find him around town. Chapman flew to New York a few times that fall, thinking about what he wanted to do. He thought about committing suicide, before deciding finally to kill Lennon. He felt that doing this would somehow lessen the problems in his own life.
