A Louisiana man claims he is the son of The Zodiac Killer in a new book that had been kept secret.
Gary Stewart, the vice president of a commercial cleaning company in Baton Rouge, said he made the discovery during the search for his biological father.
The Most Dangerous Animal of All: Searching for My Father… and Finding The Zodiac Killer was written by Stewart and award-winning author Susan Mustafa.
The book is described as "An explosive and historic book of true crime and an emotionally powerful and revelatory memoir of a man whose ten-year search for his biological father leads to a chilling discovery: His father is one of the most notorious-and still at large-serial killers in America."
Stewart reached his conclusion after 12 years of research, Tina Andreadis, a publicist at HarperCollins, told New York Magazine. HarperCollins published the book. The book has been vetted by attorneys at HarperCollins and the company feels it is legally sound, according to Andreadis.
The publisher has not reached out to the San Francisco Police Department, which investigated the deaths of at least five people in Northern California in the late 1960s and early 1970s.
The killer got his name after sending letters to press in the Bay Area. The letters included ciphers. Numerous books and movies have been made about The Zodiac Killer. None of the murders has been solved.
Andreadis did not share many details of the book with New York Magazine, but did say Stewart's father had a criminal record and there was a strong resemblance between his father's mug shot and the police sketch. Both of those bear a striking resemblance to Stewart.
Stewart has sifted through government records, news reports, conversations with his father's relatives and friends. He was able to turn up forensic evidence, identifying his father as one of the most infamous serial killers in American history, according to the book's description.
It is unclear why the book received little publicity or why it was kept secret.
Stewart is not the first person to claim he knows who the serial-killer is. According to the Los Angeles Times about 1,200 people have come forward, claiming to know the true identity.
