A new book with an outrageous claim has been flying under the radar until now. New York reports that on Tuesday, HarperCollins will release The Most Dangerous Animal of All, in which author Gary L. Stewart claims that his biological father was the infamous Zodiac Killer, who terrorized the Bay Area in the 1960s and 1970s.
HarperCollins publicist Tina Andreadis told New York's Elon Green that Stewart, a vice president at a cleaning company in Baton Rouge, concluded after 12 years of research that his father — who had a record of writing bad checks and forgeries in San Francisco — was the serial killer. Stewart also put his father's mug shot next to a police sketch of the Zodiac Killer, and was sure he was looking at the same person. "You can see that there is very clearly more than just a passing resemblance," Andreadis said. "They look alike."
HarperCollins lawyers vetted the book and "felt it was legally sound," Andreadis added. As for Stewart, who wrote the book with author Susan Mustafa, he is still reeling from his discovery. "He didn't want to believe," Andreadis said. "I don't think most people want to know that their father is a notorious serial killer."
