Zodiac Killer

Typically known for Hollywood and sunny beaches, California has been the hunting ground for a disturbing number of serial killers, as evident in Oxygen's Serial Killer Capital: Los Angeles.

The new Peacock original series looks at a professor's controversial claims that the Zodiac Killer is merely "a literary invention."

Professor Thomas Henry Horan lays out his theory that the serial killer is a hoax in The Myth of the Zodiac.

Two experts in computational linguistics studied the letters using new technology.

An upcoming Peacock documentary titled Myth of the Zodiac Killer questions whether or not the infamous killer ever actually existed.

“By the way, have the police been having a good time with the code?” the Zodiac Killer taunted police about a complex cipher in one chilling letter. “If not, tell them to cheer up; when they do crack it they will have me.” 

The unsolved murders that terrorized the Bay Area in the '60s have sparked profiles of the Zodiac Killer, dozens of suspects, and even conspiracy theories as to the murderer's identity. 

The two-part series will explore a theory that the Zodiac Killer was a hoax.

A flurry of Zodiac Killer suspects are floated in Peacock's Based On A True Story, including an Air Force veteran and journalist who worked in the area of the murders.

The Albany New York FBI Office is asking any news outlet who receives a letter from anyone calling themselves the Zodiac, not to open them, in order to preserve forensic evidence.
