As it turns out, the guy behind the Zodiac nick just confessed to be the Monster of Florence, the author of at least 7 murders of young couples in the area of Florence, Italy. Nothing official has been released to the public yet, but it seems he's a dismissed US Army officer. Here's the article in the Italian press: http://www.ilgiornale.it/news/politica/killer-zodiac-mi-ha-c...

John Douglas notes in his book 'Mindhunters' that serial killers cannot really stop. they typically continue until they 1) get locked up (typicall for something else) or 2) die. So it is super weird that the Zodiac just stopped in his 'prime'.

so, the hypothesis that _Zodiac =Monster of Florence_ would make a lot of sense, because it explains Douglas's observation. if that was the case, the Zodiac would be an absolute exception in the sense that he grew old and retired.

further, Douglas, from many years of experience of investigating serial killers, observes that killers have a 'signature'. a handwriting in their crimes, so to speak. and at first glance, the signature of the Zodiac and the Monster are very similar indeed, as others have mentioned.

Here's another, more complete article about the investigation on the Italian cases https://www.tempi.it/il-mostro-di-firenze-e-zodiac#.Ww0QVlOF...

The parallels are striking, but according to the Italian article this was announced in March, yet I can't find anything else about this.
