ANo, he was not. There have been multiple suspects, but none have even been arrested. If he is still alive, it is believed he must be at least 60 years old. It is presumed that he is dead. The case is still officially open and is regarded as a "cold case". According to Wikipedia, the case was reopened again sometime before March of 2007.
AThe movie claims to be based on "actual case files" and uses actual reports to construct the killings. In the Vallejo and Lake Berryessa attacks one of the victims survived to describe what happened. In the Paul Stine shooting witnesses saw the attack occur. In the first attack which can be conclusively attributed to the Zodiac, that of David Faraday and Betty Lou Jensen, there were no survivors or witnesses and so the film makers decided to not show the killing rather than try to reconstruct it based on forensic evidence. Robert Graysmith believes that in the Faraday/Jensen killing the Zodiac parked behind their car and approached as he did in the Ferrin/Mageau shooting. Faraday and Jensen appear to have been exiting the car and Graysmith believes that Zodiac shot Faraday first, after which Jensen tried to run and was shot.
AOn 16 August 1991, 22 years after he was shot by the Zodiac, Mike Mageau (Jimmi Simpson) is asked by Vallejo PD officer Geroge Bawart (James Le Gros) to meet him in the Ontario, California airport terminal in order to identify a photo of the man who shot him. Mageau readily identifies Arthur Leigh Allen. In the final scene, Mageau says, 'The last time I saw this face was July 4th, 1969. I'm very sure that's the man who shot me.' The movie ends, and the following postscripts appear:Following Mike Mageau's identification of Arthur Leigh Allen, authorities scheduled a meeting to discuss charging him with the murders. Allen suffered a fatal heart attack before this meeting could take place.In 2002, a partial DNA profile, that did not match Allen, was developed from a 33 year-old Zodiac envelope. Investigators in San Francisco and Vallejo refused to rule out Allen as a suspect on the basis of this test.In 2004, the San Francisco Police Department deactivated their Zodiac investigation.Today, the case remains open in Napa County, Solano County, and in the city of Vallejo, where Arthur Leigh Allen is still the prime and only suspect.Inspector David Toschi retired from the San Francisco Police Department in 1989. He was cleared of all charges that he wrote the 1978 Zodiac letter.Paul Avery passed away on December 10, 2000 of pulmonary emphysema. He was 66. His ashes were scattered by his family in the San Francisco Bay.Robert Graysmith lives in San Francisco and enjoys a healthy relationship with his children. He claims he has not received a single anonymous call since Allen's death.
