Other clues include deciphering letters sent by the Zodiac that revealed him as the killer, said Jen Bucholtz, a former Army counterintelligence agent who works on cold cases. In one note, the letters of Poste's full name were removed to reveal an alternate message, she told Fox News. "So you've got to know Gary's full name in order to decipher these anagrams," Bucholtz said. "I just don't think there's any other way anybody would have figured it out." I'd love to see that evidence.
