Major players:
Andy Russo (last known acting underboss)
Ben Castellazzo (underboss as of 2015)
William Russo (capo and son of Andy)
Ralph Lombardo (capo and former acting consigliere)
Tom Farese (Florida capo and former acting consigliere)
Joseph Baudanza (capo and former ruling panel)
Dominic Montemarano (LA soldier and former acting underboss)
Vincent Febbraro (influential soldier)
There are probably other, younger major players we haven’t heard about yet.

Big rackets:
Loansharking seems to be a constant with every Colombo bust, as does gambling
Figli di Santa Rosalia is something the Colombos control to an extent
Construction, trucking, demolition and union corruptions are still big (Tom Petrizzo, Persicos, Scopos, Garofalo, etc.)

Recently inducted members are John Cerbone (2013-2015), probably the guys from the botched 2010 ceremony (Sessa, Spata, Phil) as well as Bobby Tarantola.
