Graysmith was married to Margaret Ann Womack from 1963 to 1973. He married Melanie Krakower in 1975, but they divorced in 1980; he directly attributes his failed marriage to his intense interest in the Zodiac case.
The film Zodiac (2007), directed by David Fincher, was based on his books and featured Jake Gyllenhaal as Graysmith. Graysmith now lives in San Francisco.
Author/illustrator/cartoonist.
