@Vicious-Retard In 2007, a man named Dennis Kaufman claimed that his stepfather Jack Tarrance was the Zodiac. Kaufman turned several items over to the FBI including a hood similar to the one worn by the Zodiac. According to news sources, DNA analysis conducted by the FBI on the items was deemed inconclusive in 2010. Gary Stewart published a book, The Most Dangerous Animal of All, in which he claimed his search for his biological father, Earl Van Best, Jr., led him to conclude the man was The Zodiac Killer. In 2020, the book was adapted for FX Network as a documentary series.
