I know, old post... He many not have spent time in jail. Wiki states 2 years and the rest under house arrest, but the source of that is confusing at best. Anyone over 70 is allowed to serve their sentence at home. He was over 70 by the time he was convicted. Pic from 2013, while he was serving his sentence lol
I believe Calisto Tanzi (17 November 1938 – 1 January 2022) was out of jail when he died. Per wiki, Tanzi died of pneumonia in a Parma hospital on the New Year's Day of 2022, at the age of 83.
