The Zodiac Killer is linked to at least five murders that occurred between 1968 and 1969 in Northern California.

These letters were signed with the symbol of a crossed circle, which became the Zodiac Killer's calling card.

Suspects and Investigations

Over the years, several suspects have been considered in the Zodiac Killer case, but none have been definitively proven to be the killer. Arthur Leigh Allen, a former elementary school teacher and convicted sex offender, is one of the most notable suspects. Allen was never charged with the crimes, and he died in 1992.

In recent years, the Case Breakers, a group led by retired FBI agents, have proposed another suspect, Gary Francis Poste. They claim that Poste, who died in 2018, is the Zodiac Killer. The group points to a scar on Poste's forehead that matches a sketch of the Zodiac Killer, as well as hidden messages in the killer's letters that they claim tie Poste to the crimes. However, police and other authorities have not officially confirmed these theories.

Cultural Impact

The Zodiac Killer has had a significant cultural impact, inspiring numerous books, documentaries, and films. David Fincher's 2007 film "Zodiac" is one of the most well-known depictions of the case. The case continues to fascinate the public and remains the subject of ongoing investigations and speculations.

Conclusion

The identity of the Zodiac Killer remains unknown, and the case is still considered open by the San Francisco police and the FBI. Despite numerous theories and suspects, the true identity of the Zodiac Killer has yet to be definitively established.
