The serial murderer was linked to at least five killings in Northern California in the 1960s while taunting law enforcement with letters and codes sent to area newspapers.
The Case Breakers, formed a decade ago and led by retired FBI agents, said they now believe the Zodiac Killer was Gary Francis Poste, FOX News reported on Wednesday. Poste died in 2018.
The team spent years combing through forensic evidence and photos from Poste’s darkroom. The Case Breakers said one photo shows a scar on his forehead matching a sketch of the Zodiac Killer. Hidden messages in the murderer’s letters also tie Poste to the crimes, according to the FOX News report.
The group said they also believe Poste is responsible for killing 18-year-old Cheri Jo Bates on Oct. 31, 1966 in Riverside, California.
