The breakthrough in the investigation came when a symbol linked to the killer was found near the former property of his prime suspect, Gary Francis Post. The symbol, a cross with a circle around it, was discovered on a wooden post in Groveland, California, during brush clearing.
Post, year air forces veteran who has since died, had been a person of interest for many years.
This important discovery follows years of research by The Case Breakers, a team of elite hobbyists detectives with military and research background. His tireless search for the truth began in 2014 when a homeless man named Chris Avery approached the retired newscaster Dale Julian with a surprising statement.
According to Chris, his stepfather, Poste, was the Zodiac Killer, and had tried to kill Chris when confronted.
