While doing some research on Google. Looking up anything I could find on 1920s era Cleveland Gangster Salvatore "Black Sam" Todaro who was murdered in 1929. I managed to find the details about this documentary The Sugar Wars: The Life Story Of Angelo Lonardo the documentary was made in 2012, and according to the IMDb website its currently in post-production. The link I've included above is for the documentary trailer. Its under a minute long but from what I can tell it looks really interesting.
