The editor of, Søren Korsgaard, has published a new book, “America’s Jack The Ripper: The Definitive Account of the Zodiac Killer.”

With nearly 700 references and over 200 pictures, Søren Roest Korsgaard has produced the first authoritative book on the Zodiac, a still unidentified serial killer who terrorized California in the 1960s and proudly commemorated his murderous accomplishments in letters to news media. Søren documents the case with scholarly objectivity, and he dismantles the Zodiac’s psyche and answers major questions by means of statement analysis, linguistics, handwriting analysis, and the established principles of psychology and criminology. Among others, he presents compelling arguments and evidence that Zodiac likely started his reign of terror as far back as 1962, and that he might have been a Canadian.
