About the show
It’s one of the most complex codes in history and its author, to this day, is unknown. He’s called Zodiac – America’s most vicious serial killer who terrorized San Francisco in the late 1960s. Zodiac killed five men and women, and then left bizarre ciphers as breadcrumbs. Although studied by the most advanced criminal justice experts of the time, only 25% of his ciphers were ever decoded. Now, Sal LaBarbera – the most successful homicide detective in LAPD history – will work with a crack codebreaking team and former and current FBI investigators to hunt down Zodiac.
