Crime Library: Criminal Minds and Methods

The Zebra Killers


The only book on the subject is Clark Howard's Zebra. Although it's out of print, it remains the most complete portrayal of the Zebra Killers to date. Howard pored over police reports, court records, and conducted extensive interviews with witnesses and the murderers themselves to research the book.
