Well, what we saw in "Goodfellas" was that Tommy D killed "Billy Batts," a made man, because Batts was breaking his coglione. A colorful and dramatic story. But this is a very sketchy business because, like everything else in Mobdom, it's almost impossible to discern the truth. And "truth" is something that is in very short supply from Henry Hill, who is the source for this tall tale.
Hill said that "Billy Batts" was based on Ronald Jerrothe. But the movie Billy Batts was a made man, and Jerrothe appeared to be a hanger-on in the Gambinos. Jerry Capeci and Gene Mustain, in their book "Mob Star - The Story of John Gotti," spell his name as Jerogae, and claim that his nickname was "Foxy." They say Tommy DiSimone killed him in an argument over a girl. Not as dramatic a story as the one that Hill told. What's more, their tale shows DiSimone as a hanger-on in the Gambino family, not the Luccheses, where Hill and Burke were associates.
Another hanger-on in Gotti's crew was William Battista, whose name suggests "Billy Batts." According to Mustain and Capeci, Batts was a gambling proprietor and sometimes hijacker. He hijacked a truck while the driver was in a diner having coffee (sound familiar?). They suggest, but don't out-and-out claim, that Battista was the famous "Source BQ," who fed info to Diane Giacalone, the prosecutor in Gotti's RICO trial. Battista disappeared after Gotti was acquitted. Doesn't sound much like a made man like the movie Billy Batts.
