Much is unknown about the Zodiac killer, but given what is known about serial killers in general, this man was probably born between 1938 and 1943. That would make his age between 25 and 30 years old at the time of his first murder in Vallejo, California, in 1968. Also, that age estimate works with witness statements and it's supported by Zodiac's references to his victims in younger terms in his letters of 1969. Zodiac wasn't an attractive character from what we know. He may have had to wear glasses throughout his youth and his facial features weren't all that pleasing. So overall he may have been unpopular as a young boy and spent a good deal of time alone. It seems as though rejection is a big issue for Zodiac. No one knows anything about the Zodiac's parents but it wouldn't be ridiculous to say that there was domestic violence, broken relationships with parents or guardians, and maybe even a physical or sexual abuse in the household. Considering the adult outcome, Zodiac would have turned out to be an angry, withdrawn, loner, whose adolescence just could have been filled with fantasies and irrationality.
In California, December 20, 1968, Zodiac attacked Betty Lou Jenson and David Faraday. This was his first significant criminal act. In a matter of 2 or 3 minutes, the attack was finished and he drove casually away from the scene. He showed no signs of remorse and seemed very calm about all of his actions. After the attack of these two people-murdering the female-Zodiac would have read about his actions in local newspapers, listened to it on a radio report, or watched it on a local news report on the tv. Seven months later he attacked Darlene Ferrin and Micheal Mageau on July 4, 1969, killing the woman of course. Afterward he phoned the Vallejo Police departement to brag about what he did. He also wrote to three newspapers to brag.
By mid 1969, Zodiac would have completely controlled by his need to dominate, intimidate, and violate others, especially females and young couples. He usually killed young couples, and attacked at dusk or in the dead of night. Zodiac was not psychotic. He was in control of his actions and was also able to keep a life hidden from suspicion amounst neighbours.
Like most serial killers, no single act of violence, no matter how thrilling at the moment, seemed to last. So once again, Zodiac randomly selected a young couple as the next victims. Once again, he killed the female and failed to kill the male. It seems like he was intimidated by another man's power, maybe he was afraid to lose to a struggle. People say that killing women-for him-was the only intimate relationship he could have with one. The error was pointed out in the media that this serial killer seemed unable to kill the males. It was mysterious to people. This angered Zodiac enough for him to prove people wrong. Two weeks after his last attack, he shot a young male...
