Not a whole lot of details in the article. I would imagine that the NYC families didn't have any major bosses present or the article would have mentioned them. Gotti was under constant surveillance at the time and could not have gone to Florida unnoticed at this time period. Chin hardly ever left Greenwich Village. I assume that the Genovese and Gambinos just had their guys in Florida talk to the Chicago guys.
