Elliott Leyton, the subject of this riveting documentary by filmmaker Barbara Doran, can't help but be fascinating; that's because Leyton, who teaches at the Memorial University in Newfoundland, is also a valuable ally for law enforcement officials who need his expertise in psychology and criminal behavior to catch some of the most heinous criminals: serial killers.
