In 1938, Marcello was arrested and charged with the sale of more than 10 kg (23 pounds) of marijuana. Despite receiving another lengthy prison sentence and a $76,830 fine, Marcello served less than ten months and only paid a $400 fine thanks to a deal cut with former Gov Long. On his release from prison, Marcello became associated with Frank Costello, the leader of the Genovese crime family, in New York City. At the time, Costello was involved in transporting illegal slot machines from New York City to New Orleans. Marcello provided the muscle and arranged for the machines to be placed in local businesses.
