In the 1960s to the early 1990s the ndrangheta and the mafia in minor manner kidnapped the rich people in North Italy and made billions lires with the ransoms.
I dont think to kidnap people in NY but organizate to kidnap the son of a wealthy bussiness man and ask for money when was more hard to find someone because no cameras on the corner,no wiretrap ecc or was more profitable to kidnap powerful bosses parents like Manny Gambino?
