There were several murder cases involving the ILA in Brooklyn during the 1930s and 1940s. Among them the Peter Panto murder in 1939. http://en.wikipedia.org/wiki/Pete_Panto

Most of the killings were attributed Albert Anastasia, but let´s not forget that the ILA in Brooklyn was originally Vincent Mangano´s bread and butter. And as boss of the (early) Gambino Family, he wielded a lot of power in that racket.

Vincent Mangano´s younger brother Philip, seems to have been directly involved with murder, more so than Vincent. Well, according to his rap sheet. Philip was arrested in 1923 and questioned in the Giovanni Pecoraro murder. (Pecoraro´s son "Skinny Mike" later became a made member of the Gambino Family.) Philip was also picked up in 1924 and questioned in the Joe DiCarlo murder in Buffalo. (DiCarlo was the son of the former Buffalo boss Joseph Peter.) But none of this led to any charges or indictments.

Correction - Philip Mangano was questioned for the murder of a WITNESS AGAINST Joe DiCarlo. And he WAS charged in the Giovanni Pecoraro murder but acquitted.
