Zodiac Killer - 1968-1969

The Zodiac Killer was a serial killer who operated in northern California in the late 1960s and early 1970s. 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. The killer originated the name "Zodiac" in an August 7, 1969 letter to the local Bay Area press, which was just one in a series of taunting letters. These letters included four cryptograms (or ciphers). Of the four cryptograms sent, only one has been definitively solved.

Suspects have been named by law enforcement and amateur investigators, but no conclusive evidence has surfaced. In April 2004, the San Francisco Police Department (SFPD) 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 County and Solano County. The California Department of Justice has maintained an open case file on the Zodiac murders since 1969.

The following murder victims are suspected to be victims of Zodiac, though none has been confirmed:

• Robert Domingos, 18, and Linda Edwards, 17: shot and killed on June 4, 1963, on a beach near Gaviota. Edwards and Domingos were identified as possible Zodiac victims because of specific similarities between their attack and the Zodiac's attack at Lake Berryessa six years later. Coordinates: 34°28′11.20″N 120°10′7.14″W
• Cheri Jo Bates, 18: stabbed to death and nearly decapitated on October 30, 1966, at Riverside City College in Riverside. Bates's possible connection to the Zodiac only appeared four years after her murder when San Francisco Chronicle reporter Paul Avery received an anonymous tip regarding similarities between the Zodiac killings and the circumstances surrounding Bates's death.^[6] College coordinates: 33°58′19″N 117°22′52″W
• Donna Lass, 25: last seen September 6, 1970, in Stateline, Nevada. A postcard with an advertisement from Forest Pines condominiums (near Incline Village at Lake Tahoe) pasted on the back was received at the Chronicle on March 22, 1971, and has been interpreted as the Zodiac claiming Lass's disappearance as a victim. No evidence has been uncovered to connect Lass's disappearance with the Zodiac Killer definitively.

There is also a suspected third escapee from the Zodiac Killer:

• Kathleen Johns, 22: allegedly abducted on March 22, 1970, on Highway 132 near I-580, in an area west of Modesto. Johns escaped from the car of a man who drove her and her infant daughter around the area between Stockton and Patterson for approximately 1½ hours. Junction 132/I-580 coordinates: 37°38′16.14″N 121°23′55.22″W

  On August 1, 1969, three letters prepared by the killer were received at the Vallejo Times Herald, the San Francisco Chronicle, and The San Francisco Examiner. The nearly identical letters took credit for the shootings at Lake Herman Road and Blue Rock Springs. Each letter also included one-third of a 408-symbol cryptogram which the killer claimed contained his identity. The killer demanded they be printed on each paper's front page or he would "cruse around all weekend killing lone people in the night then move on to kill again, until I end up with a dozen people over the weekend"

  "I LIKE KILLING PEOPLE BECAUSE IT IS SO MUCH FUN IT IS MORE FUN THAN KILLING WILD GAME IN THE FORREST BECAUSE MAN IS THE MOST DANGEROUE ANAMAL OF ALL TO KILL SOMETHING GIVES ME THE MOST THRILLING EXPERENCE IT IS EVEN BETTER THAN GETTING YOUR ROCKS OFF WITH A GIRL THE BEST PART OF IT IS THAE WHEN I DIE I WILL BE REBORN IN PARADICE AND THEI HAVE KILLED WILL BECOME MY SLAVES I WILL NOT GIVE YOU MY NAME BECAUSE YOU WILL TRY TO SLOI DOWN OR ATOP MY COLLECTIOG OF SLAVES FOR MY AFTERLIFE EBEORIETEMETHHPITI"

  — The solution to Zodiac's 408-symbol cipher. Graysmith stated in 1976 that the meaning, if any, of the final eighteen letters has not been determined^[

  The Chronicle published its third of the cryptogram on page four of the next day's edition. An article printed alongside the code quoted Vallejo Police Chief Jack E. Stiltz as saying "We're not satisfied that the letter was written by the murderer" and requested the writer send a second letter with more facts to prove his identity. The threatened murders did not happen, and all three parts were eventually published.
  On August 7, 1969, another letter was received at The San Francisco Examiner with the salutation "Dear Editor This is the Zodiac speaking." This was the first time the killer had used this name for identification. The letter was a response to Chief Stiltz's request for more details that would prove he had killed Faraday, Jensen and Ferrin. In it, the Zodiac included details about the murders which had not yet been released to the public, as well as a message to the police that when they cracked his code "they will have me."
  On August 8, 1969, Donald and Bettye Harden of Salinas, California, cracked the 408-symbol cryptogram. It contained a misspelled message in which the killer said he was collecting slaves for the afterlife. No name appears in the decoded text, and the killer said that he would not give away his identity because it would slow down or stop his slave collection.
