Cabrini-Green
Long time since we spoke and you hear about the remnants of the projects still at it now ( MC v GD)?.
Off topic but back to Marcello...

I understand his influence with others as being a traditional Sicilian don and yes he network with other racketeers down here along the Gulf Coast. There's a slight difference between doing business and staking territory. Organized Crime down South ( Non LCN) is not well documented outside certain major cities and Kingpins. I'm still reading and researching as we speak about Organized Crime in my state ( Sip) and currently reading Southern Justice about the Dixie Mafia and Shirley murders. So far Marcello have been mentioned once so far and it was a contractual business.

Read about other cities Houston , Memphis, Atlanta ( mobsters couldn't get a stronghold on the Gambling due to local syndicates), and Nashville too. That's why I'm stating that his territory is N.O metro and add other nearby areas of Louisiana.
