Hi everyone,

Couple of questions.

The first is pretty straight forward for anyone with in-depth knowledge of the case, what was the last Zodiac activity that is officially confirmed ie last confirmed killing, letter or cipher recorded and is there any unconfirmed potential Zodiac activity that followed this as well?

The second question I have is whether any of the suspects could well have known each other, I’m sure I read there was a possibility ALA and FM knew each but could any of the other suspects potentially been colleagues or friends?

Thanks,
