International Narcotics, Money Laundering, and Racketeering Section (INMLRS)

Section Overview

The section focuses on investigations and prosecutions of international and significant domestic narcotics trafficking and money laundering organizations, violent local criminal street gangs, and both traditional and emerging transnational organized criminal enterprises. Using the full panoply of federal drug trafficking, money laundering, other financial and tax, racketeering, and frauds laws, AUSAs in the section work on cases which are part of the OCDETF National Program and target the leaders and associates of the Mexican and Colombian drug cartels, including the Jalisco New Generation Cartel (“CJNG”), and affiliated drug trafficking syndicates, as well as criminal networks which import heroin, fentanyl, and chemical precursors, often manufactured in Chinese clandestine laboratories, through the borders, ports, and mail systems. The section is at the national forefront of combating the opioids epidemic, working with law enforcement partners to investigate and prosecute “dirty doctors,” pharmacies, and street-level and whole-sale distributors, as well as websites which facilitate the distribution of hydrocodone and oxycodone and other drugs, particularly where such distribution results in serious bodily harm or overdose death. In addition, AUSAs in the section have developed an expertise in investigating and prosecuting transnational organized criminal groups and domestic vendors who distribute narcotics and launder the proceeds of their criminal conduct through the dark web and the use of crypto-currency. The section seeks to dismantle entire drug trafficking organizations and transnational organized criminal enterprises including by attacking their ability to utilize financial systems and methods outside of such traditional systems like the “hawala” to transfer their ill-gotten gains. The section prosecutes sweeping international money laundering conspiracies and handles cases involving money laundering, Bank Secrecy Act, and other economic sanctions violations as well as the forfeiture of crime proceeds and assets. The section has prosecuted Consolidated Priority Organizational Targets (“CPOTs”) and various drug kingpins who have been extradited to the United States to face substantial prison sentences. The section is an active participant in the Department of Justice’s priority program of combating violent crime by aggressively using the Racketeer and Influence Corrupt Organization, drug trafficking, and money laundering statutes to prosecute the Mexican Mafia prison gang and its affiliated violent Hispanic street gangs which distribute narcotics in local communities and in the incarceration systems.

AUSAs in the section work with various federal and local law enforcement entities, including DEA, FBI, DHS, ATF, IRS, the Coast Guard, the United States Marshals, task forces such as the High Intensity Drug Trafficking Area (“HIDTA”), the California Bureau of Narcotic Enforcement, the California Department of Corrections and Rehabilitation, the Los Angeles Police Department and other local police departments, and the Los Angeles Sheriff’s Department. In addition, the section also actively works with foreign prosecutors and law enforcement agency counterparts in order to investigate, prosecute, and extradite foreign nationals as well as United States citizens who commit crimes abroad. AUSAs in the section regular engage in community outreach as part of the office’s anti-drug and anti-gang efforts.
