Originally released in 2007 His Name Was Arthur Leigh Allen is a documentary which was included in the Special Edition DVD of Zodiac the feature film. Through a number of interviews with the original investigators and surviving victims this documentary covers every aspect of the investigation into discovering the true identity of The Zodiac Killer.
The Zodiac Killer was a serial killer who who operated in Northern California from at least the late 1960s to the early 1970s. Although never formally charged with the murders, Arthur Leigh Allen was the primary suspect as so much evidence pointed towards him.
Doesn’t make sense that a man who has a strong interest in children would suddenly become a serial killer of adults. Surely if his obsession was with kids, then he would target kids in some way or form. Never thought Arthur Leigh Allen was the Zodiac Killer. My prime suspect, based on a large amount of circumstantial evidence, would be Richard Hoffman.
