I can't find any information on former Genovese acting boss Daniel Leo besides the information on Wikipedia.

I got questions like:

When did Leo go on record with the Genoveses?

When did Leo get made?

When did Leo become a capo?

What rackets was Leo involved in?

Was Leo ever caught on tape?

He did only one prison sentence and before that he only had one conviction for contempt of court. The guy must have been real low key.
