The Zodiac Killer: Case Closed?
It’s one of the most complex codes in history, which experts say rivals the Rosetta Stone and Enigma in its brilliance. To this day its author is unknown. He’s called Zodiac - America’s most vicious serial killer, who terrorised San Francisco in the late 1960s. Zodiac killed five men and women, leaving behind bizarre ciphers. Now, Sal LaBarbera - the most successful homicide detective in LAPD history - will work with a crack team of codebreakers, including former Google employees and FBI investigators to hunt down Zodiac. The key: a groundbreaking new investigative technique called a Double Helix Investigation. As Sal and his partner Ken Mains uncover new evidence, they’ll feed it to Kevin Knight, who has created a new codebreaking system called Carmel. Carmel will use this new information about Zodiac’s identity - his movements, his behaviour and tactics - to detect new patterns in the Zodiac codes, which will then be fed back to Sal and Ken in the field.
