The Colombians are crazy enough to not give a shit about the mafia. I never heard for sure, but like Paulie said I think El Negro aka Carlos Vanegas. They called him El Negro because of course he was real dark. As crazy as they were they probably would have popped him if they could have and I'm not sure the Italians could have done much about it.

As far as power they were the strongest of all the Colombians at the time as they were tied to Pablo Escobar and the Ochoa's. They worked under Griselda Blanco and you couldn't get any higher in the U.S. than they were.

These were guys stupid enough to bayonet a Colombian who just got off a plane at the Miami Airport because she wanted him to die like a pig. They had the "Murder Wagon" at Dadeland Mall as well.
