Internet rumor taken at face value by some aside, there's no actual crew in Chicago Heights/NW Indiana. Going back to the Family Secrets case in 2005, there were 4 crews identified by the FBI - Elmwood Park, Grand Avenue, Melrose Park, and the South Side/26th Street crew. More recently, in 2011, the feds said the Outfit was down to "two or three crews." Even back in the later 1990's, the only crews the FBI was bothering to investigate were the Melrose Park crew and the South Side/26th Street crew.

I don't know if "fractured" is the word but there does apparently seem to be a divide of sorts. In a very real way, the day-to-day leadership of the Outfit seems to be out of the Melrose Park crew - recently Mike Sarno and Jimmy Marcello before him. The DiFronzos, Andriacchi, and the Elmwood Park crew seem to be keeping most others at arm's length while they just do their own thing - mostly legit or quasi-legit businesses. DiFronzo's companies, trade shows, strip clubs, some bid-rigging, etc.
