His January posts on “ The Zodiac Killer - Unsolved & Unforgotten, ” claiming that he solved the ciphers, have also been removed by the moderator.ĭavid Oranchak, part of the international code-breaking team who solved 340, told the New York Times, "it is practically impossible to determine if any of them are correct” because they're too short to verifiably establish a pattern.

“When he says that it took two weeks to crack the Z32 and an hour for the Z13, I think that sums it up pretty well.” “I don’t believe it for a second,” on commenter on wrote. A moderator removed his comments within 30 minutes of posting, arguing that the cipher was too short to be solved at all. His claims have been met with significant skepticism within the online community. Ziraoui began posting about his findings in January on, a forum where sleuths discuss the ciphers and overall theories on the case. Z32 was also received by the Chronicle in 1970, along with a postcard threatening to "wipe out a school bus,” according to SFGate. He deciphered the sentence, “LABOR DAY FIND 45.069 NORT 58.719 WEST” in Z32, which refers to coordinates based on the earth’s magnetic field and which Ziraoui says match up near a school in South Lake Tahoe.

Ziraoui claims he found further evidence through his decoding to show that Kaye was the killer.

He died in 2010 and was never officially named a suspect. Kaye, a salesman and career criminal, lived in South Lake Tahoe. He came up with “KAYR,” which is close to Lawrence Kaye, once eyed as a possible suspect in the case.

However, Ziraoui claims he cracked both in two weeks using the key used to solve the 340 Cipher, so-called because it contained 340 characters and symbols. He told the New York Times that he figured out the killer’s identity in about an hour. Two remaining ciphers, dubbed " Z13" and "Z32" have long remained unsolved, much to the frustration of many as Z13 was sent to the San Francisco Chronicle in 1970 with the statement "My name is" followed by 13 letters and symbols, tantalizing sleuths that the killer's identity was within reach. High school teacher Donald Harden and his wife Bettye were able to decode the message, which read in part “I like killing people because it is so much fun." The first cipher was cracked by private citizens in 1969. All the while, he taunted the public about his crimes, infamously sending the media coded messages.

That cipher is one of four disseminated by the serial killer, responsible for terrorizing Northern California by committing five brutal murders between 19.

A team from the United States, Australia, and Belgium seemingly solved the so-called "340 Cipher" the elusive killer sent to The San Francisco Chronicle 52 years ago. However, both the Zodiac and cipher communities aren't exactly buying it.įayçal Ziraoui became inspired to crack the ciphers back in December after learning that code-breakers solved another mysterious cipher created by the killer, the New York Times reports. A French engineer claims to have cracked the two remaining ciphers created by the Zodiac Killer, including one purportedly revealing the serial killer’s identity.
