The gold trade was one part of the sanctions-evasion scheme, which lasted at least five years and represented only a portion of Zarrab’s money-laundering business. An itemized inventory discovered by U.S. prosecutors outlined Zarrab’s high-value assets in 2014: six expensive racehorses, 17 luxury cars, more than $10 million in artwork, 24 firearms used by his security detail, and 20 properties in his name with three more held through his business or family. The list also included seven sea-going vessels registered to Maltese and U.S. limited liability corporations.
