How many men did Frank Sheeran kill?

Apart Robert DeGeorge in 1967 but the case was dismissed;
The others was confessed by Sheeran in his book,apart Anastasia e Joe Gallo or Hoffa or Briguglio (that for sure are invented) there are two men in Philadelphia.
Francis J. Marino (1976)
Frederick John Gawronski (1976)

Thank you Furio

Nowhere near the 25-30 he claims I think. Although the FBI had a terrible record those days to solve any 'mob' murder case.

Furio who were those two men and who ordered the hits?

Both men was in labour racketeering. I don't remember who ordered the hits but for sure Russell Bufalino because Sheeran was indicted with Bottone and Allen that was with Bufalino.
