French Engineer Claims To Have Finally Cracked The Zodiac Killer’s Last Two Unsolved Ciphers

In the 1960s and 1970s, the Zodiac Killer terrorized Northern California. He left several clues in his wake, including a handful of coded messages. But for years, authorities and amateur sleuths have failed to crack the last of his unsolved ciphers.

But now, Fayçal Ziraoui, an engineer and business consultant who lives outside of Paris, claims to have finally decoded the Zodiac Killer’s final two unsolved ciphers, called Z13 and Z32 for the number of coded characters each contains. One, he says, even reveals the killer’s name: Lawrence Kaye, a suspect in the original case.

“I was obsessed with it, 24 hours a day, that’s all I could think about,” explained Ziraoui, who learned about the Zodiac Killer in a French magazine.

In 1969 and 1970, the Zodiac Killer sent out four ciphers along with letters describing his crimes. The first, sent on July 31, 1969, was cracked just a week later.
