While on trial accused of a "massacre" ('strage Erba'), the accused writes down a long series of enciphered notes in a bible... the cipher then gets broken (by Andrea Rizzi, Gregorio Guidi, and Roberto Frigerio), revealing the defendant's thoughts on many (probably too many) aspects of the case. The trial continues: there is extensive coverage on the Wildgreta blog (in Italian). I've tried to find online pictures of the cipher (without success): but as it has already been definitively cracked (it would seem), there's no huge sense of urgency.
Cryptographically, the tragedy is that it sounds (by all accounts) like a monoalphabetic cipher with a few nulls that even Cicco Simonetta's Regule could have cracked 550 years ago (I'm sure Augusto Buonafalce and Marcello Simonetta would agree); while the Voynich Manuscript (from the same era) still can't be decrypted today. Madness. :-(
