Author's Note: 10 of the World's Most Prolific Serial Killers

I'm a little uneasy with the subject, I confess, because I've actually met one of the killers on this list, as well as relatives of his victims. As a young newspaper reporter in California in the late 1980s, I covered the trial of serial killer Randy Kraft, and once paid a brief visit to him in jail in an unsuccessful effort to get an interview. On the other side of the glass barrier, I got to see how his placid, almost meek demeanor could morph suddenly into a frightening rage, as he slammed down the phone and stomped off. But what affected me more was meeting and spending time with the mother of one of his victims, and I saw for myself the unending torment that the killer's sadistic cruelty had inflicted upon her. Even so, she was so gentle and kind that she was reluctant to see her son's murderer receive the death penalty. Those experiences taught me lessons about both the darkest, most disturbing part of human nature, and its highest, most noble side as well.
