On Oct. 6, 2021, an independent team of 40 ex-law enforcement investigators, who call themselves the Case Breakers, claimed they had identified the Zodiac Killer, according to a press release obtained by CNN. Using new physical and forensic evidence and information from eyewitnesses, the team was able to identify the killer as a man named Gary Francis Poste. However, they noted that they believe he passed away in 2018.

The Case Breakers also believe that Poste was responsible for the unsolved 1966 murder of Riverside County, Calif. woman Cheri Jo Bates. However, the Riverside County Police Department's public information officer Ryan Railsback does not believe that claim. He told the outlet that the only link between the Bates murder and the Zodiac Killer was that the Bates murderer sent a handwritten letter by mail claiming responsibility.

Currently, Poste is just a suspect. "We are unable to speak to potential suspects as this is still an open investigation," the San Franciso Police Department said in a statement. The FBI, which has been supporting local law enforcement in the investigation, has not yet acknowledged the Case Breakers claims.

"The Zodiac Killer case remains open. We have no new information to share at the moment," the FBI said in a statement provided to CNN.
