I saw this today on the BBC News website – Zodiac Killer: Code-breakers solve San Francisco killer’s cipher: https://www.bbc.com/news/world-us-canada-55285805. Video and photos are in the link. There are a couple of other coded messages that have not been decoded.

Code-breakers have cracked a 340-character cipher 51 years after it was purportedly sent to the San Francisco Chronicle by the so-called Zodiac Killer, the FBI has confirmed.
The killer, who was never caught, murdered five people in stabbings and shootings that terrorised the San Francisco Bay area in the late 1960s.
The message was one of several sent to newspapers during the killing spree.
The code was solved by three people from the US, Belgium and Australia.
“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 paradice (sic) all the sooner because I now have enough slaves to work for me,” the decrypted message reads, without throwing any light on the killer’s identity.
In a video posted on YouTube, Virginia web-designer David Oranchak says he cracked the cipher along with Australian applied mathematician Sam Blake and Belgian Jarl Van Eycke, a warehouse manager and code-breaking software engineer.
