That's a link to his book but I haven't read it yet. Reviews say its good though.

That's an article about when Cantalupo testified at Funzi Tieri's trial. He said that Funzi threatened his uncle into not selling pizzas in a particular spot, sent someone after him to make sure he paid a $10,000 loan from Funzi and that his apartment was used as a meeting spot for Joe Colombo, Funzi Tieri and Carlo Gambino. Cantalupo testified he had worked with the Colombo family for 14 years, committing robberies and loan sharking.


And thanks for mentioning that book BillyBrizzi. Crime Inc is my favourite series on the mob by far.
