Warehouse manager helps crack Zodiac killer code

The code had been unsolved for 51 years.

Belgian Jarl Van Eycke is a warehouse manager and code-breaking software engineer. US web-designer David Oranchak and Australian applied mathematician Sam Blake also worked on the code.

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 reads ‘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.’
