When the sun went down on July 3, 2019, the men on the yacht sprang into action, unloading large white coolers from the boat. At the sight of the coolers, the police swooped in. When they flicked on their sirens and their lights, three crewmen made a run for it. One tried to swim away. All were apprehended, along with 421 kilograms of cocaine in the yacht’s stateroom.
