What do you mean by defunct? Do you mean when the last member dies?
As far as I'm (and the feds for that matter) concerned, Kansas City and Los Angeles are already defunct.
There are 10 families left if you count Detroit. They would be the next to go.
Not counting Detroit, I think an argument could be made for either the DeCavalcantes or Chicago. But that's years down the road.
Genovese are the next to be defunct. Most secretive, not a lot of information out there about them from law enforcement. Its almost like its a secret society and we aren't supposed to know that much about them or something!
