Who Was Gary Francis Poste? Full Biography, Death, and Zodiac Allegations Explained
Poste's transformation from deceased rural tradesman to international true crime fixture began when The Case Breakers took up his trail. The team, led by former investigative journalist Thomas J. Colbert and composed of retired military intelligence officers, former detectives, and private researchers, spent months assembling circumstantial patterns connecting Poste to the Zodiac killings of 1968 and 1969.
Their central visual argument rested on a famous 1969 police sketch distributed after the murder of cab driver Paul Stine in San Francisco's Presidio Heights. The drawing featured prominent furrowed lines on the killer's forehead. Old photographs of Poste revealed matching physical scars across his brow, reportedly sustained during a severe military vehicle collision in the 1950s. The team maintained that these markings were too distinctive to be coincidental.
Beyond physical resemblance, The Case Breakers argued that Poste's full legal name functioned as an essential decryption key. By removing the letters of "GARY FRANCIS POSTE" from one of the Zodiac's uncracked encrypted dispatches, they claimed an alternate hidden message emerged. They also gathered testimony from former acquaintances who alleged Poste ran a heavily armed mountain posse and handed away weapons before his death, including a collection of paint-spattered wristwatches.
