The second Chicago family had two or maybe three bosses (Sanfilippo, Piazza and possibly Martino or Nerone) and by 1925 they were eliminated by the mainlanders such as the Robertos and Emery. It seems the Chi Heights family was in close alliance with the Gennas from the West Side which were also exterminated during 1924/25 or during the same time. Love these stuf, especially when I read regarding mainlanders killing old school or traditional mafia sicilians.
