[3] Agron emigrated to the United States, arriving at John F. Kennedy International Airport in New York City on October 8, 1975 and listing his occupation as a jeweler.
[3] He swiftly gained control of criminal operations among the Soviet Jews living in the Brighton Beach neighborhood of Brooklyn, and with the assistance of his enforcers Emile Puzyretsky and the Nayfeld brothers, Benjamin and Boris, oversaw a lucrative extortion ring in the Russian émigré community, which by 1980 was worth tens of thousands of dollars per week.
[3] As boss of the most powerful Russian crime group in New York, Agron oversaw a gang which operated in at least six North American cities and branched out into truck hijacking, jewelry heists and Medicaid fraud.
While recovering at Coney Island Hospital, Agron was questioned by a police officer and asked if he knew the identity of the man who had shot him.
In 1983, federal agents uncovered a multi-million dollar fraud perpetuated jointly by Agron and Wilson relating to the skimming of profits from the Dunes hotel and casino in Las Vegas, which was owned by Morris Shenker.
This type of fraud, which involved selling tax-free home heating oil as diesel fuel, eventually cost the state of New Jersey alone an estimated $1 billion annually in lost tax revenues.
[9] In January 1984, Agron survived a second assassination attempt when he was shot twice in the face and neck as he ascended a gentle slope from the garage in the basement of his home on 100 Ocean Parkway in Brooklyn.
He was operated on at Coney Island Hospital by Dr. Larissa Blinkin, who was unable to remove the bullets lodged in Agron's body but did save his life.
