The Zodiac Killer was a serial killer who operated in northern California in the late 1960s and early 1970s. He is believed to have killed at least five people and wounded two others, but claimed in letters to newspapers to have killed many more. The case remains unsolved to this day, making it one of the most famous unsolved mysteries of the 20th century.

The first confirmed killing attributed to the Zodiac occurred on December 20, 1968, when two teenagers were shot and killed in their car in Vallejo, California. The killer then sent a letter to the Vallejo Times-Herald, claiming responsibility for the murders and including a cryptogram that he said contained his identity. He threatened to kill more people if the paper did not publish the cryptogram on its front page.

Over the next two years, the Zodiac went on to kill at least four more people and wound two others in northern California. He sent letters and cryptograms to newspapers, police departments, and individuals, taunting the police and the public with clues to his identity.

The Zodiac's letters and cryptograms were often cryptic and filled with misspellings, making them difficult to decipher. One letter contained a diagram of a bomb that the Zodiac claimed he would use to blow up a school bus full of children. He demanded that the letter be printed on the front page of the San Francisco Chronicle, or he would "cruse [sic] around all weekend killing lone people in the night."

Despite the public's fascination with the case, and a massive manhunt by police, the Zodiac was never caught. He continued to send letters and cryptograms until 1974, when his communications abruptly stopped.

The case has been the subject of numerous books, movies, and television shows, but the killer's identity remains a mystery. Over the years, many suspects have been named, including Arthur Leigh Allen, a convicted child molester who died in 1992. However, no one has ever been charged with the crimes.

One of the reasons the Zodiac case remains so intriguing is the killer's use of cryptograms and codes. Despite decades of effort by amateur and professional codebreakers, only one of the Zodiac's cryptograms has been solved. In 1969, the killer sent a letter to the San Francisco Examiner that contained a 408-symbol cryptogram. The solution, which was found by a couple in Salinas, California, read: "I like killing people because it is so much fun."

Other cryptograms sent by the Zodiac have yet to be solved, including one that the killer claimed contained his identity. The FBI has released some of the cryptograms to the public, hoping that someone will be able to crack the code and provide new leads in the case.

The Zodiac's letters and cryptograms were not his only method of taunting the police and the public. He also called several police departments, giving them clues to his identity and bragging about his crimes. In one call, he claimed to have killed 37 people, although only five confirmed murders have been attributed to him.

The Zodiac's letters and phone calls were often accompanied by strange symbols and drawings, including a circle with a cross through it that has become one of the most recognizable symbols of the case. The meaning of the symbol remains a mystery, although it has been speculated that it could represent everything from a target to a Zodiac calendar.

Despite the lack of progress in the case, the public's fascination with the Zodiac has never waned. The case has inspired countless amateur investigators and armchair detectives, many of whom have spent years poring over the letters and cryptograms in search of clues to the killer's identity.

In recent years, new technologies have been used in an effort to solve the case. In 2007, the San Francisco Police Department announced that they had developed a DNA profile of the killer, using genetic material from the back of stamps used on some of the Zodiac's letters. However, a match has not yet been found in any DNA databases, and the case remains unsolved.

In 2020, the case received renewed attention when the FBI announced that they had solved a cipher sent by the Zodiac in 1969. The cipher read: "I hope you are having lots of fun in trying to catch me. ... I am not afraid of the gas chamber because it will send me to paradise all the sooner because I now have enough slaves to work for me." While the solution did not reveal the killer's identity, it did provide a chilling insight into his mindset.

Despite the lack of progress in the case, the legacy of the Zodiac Killer lives on. His letters, cryptograms, and symbols have become the stuff of legend, inspiring countless books, movies, and television shows. The case has also had a profound impact on law enforcement, leading to changes in the way police investigate serial killers and prompting the creation of the Behavioral Analysis Unit (BAU) at the FBI.

In conclusion, the Zodiac Killer remains one of the most famous unsolved mysteries of the 20th century. His letters, cryptograms, and symbols have captivated the public's imagination for over 50 years, and his identity continues to elude law enforcement. While new technologies and investigative techniques may one day provide the breakthrough needed to solve the case, for now, the Zodiac remains a mysterious figure, shrouded in myth and legend.
