The Bay’s Most Infamous Killer

By Adam Sarsfield

The Zodiac Killer is a notorious unidentified serial killer who operated in Northern California during the late 1960s and early 1970s. The case was one of the most infamous unsolved mysteries in American criminal history until this recent discovery.

The Zodiac Killer first came to public attention in 1969, when he began sending letters to the San Francisco Chronicle and other newspapers. In these letters, the Zodiac claimed responsibility for a series of murders and threatened to kill more people if his letters were not published. He also included cryptograms, which he claimed would reveal his identity if they were solved. The Zodiac Killer’s crimes were particularly brutal and included the murders of at least five people, as well as several other attacks. The victims were often young couples who were parked in secluded areas. The Zodiac would approach them, shine a flashlight in their eyes, and then open fire. Some victims survived the attacks and were able to provide descriptions of their attacker. Despite an extensive investigation and numerous suspects, the Zodiac Killer was never caught. Several people had confessed to the crimes over the years, but none of these confessions had been conclusively proven to be authentic. The case remains open and continues to fascinate people around the world. The Zodiac’s cryptograms had inspired countless amateur and professional code breakers, and many theories had been put forth about the killer’s identity and motives. In recent years, advances in DNA technology have led to renewed interest in the case. The Zodiac Killer’s identity had remained unknown until recently in 2022 a team of 40 amateur investigators, collectively known as the Case Breakers, had identified the late Gary Francis Poste, a US air force veteran, as the Zodiac Killer however with Poste having passed in 2018 there was no way to receive justice for the victims and their families.
