Born in Leningrad, Agron immigrated to the United States under the Jackson-Vanik Amendment in 1975. He swiftly gained control of criminal operations among the Soviet Jews living in Brighton Beach. Agron organized a motor fuel racket which would earn millions, if not billions, through fuel tax fraud.
