My daddy was the Zodiac Killer May 13 2014
This is odd: Gary Stewart has written a book about the search for his biological father and through the process discovered his father is the still-uncaught Zodiac Killer. The book's description promises new "forensic evidence".
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.
Soon after his birth mother contacted him for the first time at the age of thirty-nine, adoptee Gary L. Stewart decided to search for his biological father. It was a quest that would lead him to a horrifying truth and force him to reconsider everything he thought he knew about himself and his world.
