The Zodiac Killer was a serial killer who operated in Northern California in the late 1960s. The Zodiac killer's identity remains unknown. The Zodiac killer coined the name "Zodiac" in a series of taunting letters sent to the local Bay area press. These letters included four cryptograms (or ciphers), three of which have yet to be solved.
The Zodiac murdered victims in Benicia, Vallejo, Lake Berryessa, and San Francisco between December 1968 and October 1969. Four men and three women, between the ages of 16 and 29, were targeted. Numerous suspects have been named by law enforcement and amateur investigators, but no conclusive evidence has surfaced.
In April 2004, the San Francisco Police Department marked the case "inactive", yet re-opened the case at some point prior to March 2007. The case also remains open in the city of Vallejo as well as in Napa Counties and Solano Counties. The California Department of Justice has maintained an open case file on the Zodiac murders since 1969.

Can you crack the famous unsolved Zodiac 340-character cipher? The SF Chronicle published this cipher that was mailed to them by the Zodiac killer back in 1969. The first cipher he sent was solved by a high school teacher and his wife. The 340-character cipher below remains unsolved. Can you solve it?

Arthur Leigh Allen (December 18, 1933 – August 26, 1992) was the primary suspect in the Zodiac Killer investigation. While being investigated Allen passed a polygraph test, had his fingerprints compared to those at the murder scene of known Zodiac victim Paul Stine and had his handwriting examined. In 2002, a DNA comparison to a sample found on one of the stamps of the Zodiac letters did not match Allen's.
